6 See the end for copying conditions.
8 * Version 3.6.10 (unreleased)
10 ** libgnutls: Added support for deterministic ECDSA/DSA (RFC6979)
11 Deterministic signing can be enabled by setting
12 GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE when calling gnutls_privkey_sign_*()
15 ** libgnutls: add gnutls_aead_cipher_encryptv2 and gnutls_aead_cipher_decryptv2
16 functions that will perform in-place encryption/decryption on data buffers (#718).
18 ** libgnutls: added interoperability tests with gnutls 2.12.x; addressed
19 issue with large record handling due to random padding (#811).
21 ** API and ABI modifications:
22 gnutls_aead_cipher_encryptv2: Added
23 gnutls_aead_cipher_decryptv2: Added
26 * Version 3.6.9 (released 2019-07-25)
28 ** libgnutls: add gnutls_hash_copy/gnutls_hmac_copy functions that will create a copy
29 of digest or MAC context. Copying contexts for externally-registered digest and MAC
30 contexts is unupported (#787).
32 ** Marked the crypto implementation override APIs as deprecated. These APIs are rarely
33 used, are for a niche use case, but have significant side effects, such as preventing
34 any internal re-organization and extension of the internal cipher API. The APIs remain
35 functional though a compiler warning will be issued, and a future minor version update
36 may transform them to a no-op while keeping ABI compatibility (#789).
38 ** libgnutls: Added support for AES-GMAC, as a separate to GCM, MAC algorithm (#781).
40 ** libgnutls: gnutls_privkey_sign_hash2 now accepts the GNUTLS_PRIVKEY_SIGN_FLAG_TLS1_RSA
41 flag as documented. This makes it a complete replacement of gnutls_privkey_sign_hash().
43 ** libgnutls: Added support for Generalname registeredID.
45 ** The priority configuration was enhanced to allow more elaborate
46 system-wide configuration of the library (#587).
47 The following changes were included:
48 - The file is read as an ini file with '#' indicating a comment.
49 - The section "[priorities]" or global follows the existing semantics of
50 the configuration file, and allows to specify system-wide priority strings
51 which are accessed with the '@' prefix.
52 - The section "[overrides]" is added with the parameters "insecure-hash",
53 "insecure-sig", "insecure-sig-for-cert", "disabled-curve",
54 "disabled-version", "min-verification-profile", "tls-disabled-cipher",
55 "tls-disabled-mac", "tls-disabled-group", "tls-disabled-kx", which prohibit
56 specific algorithms or options globally. Existing algorithms in the
57 library can be marked as disabled and insecure, but no hard-coded
58 insecure algorithm can be marked as secure (so that the configuration
59 cannot be abused to make the system vulnerable).
60 - Unknown sections or options are skipped with a debug message, unless
61 the GNUTLS_SYSTEM_PRIORITY_FAIL_ON_INVALID environment parameter is
64 ** libgnutls: Added new flag for GNUTLS_CPUID_OVERRIDE
65 - 0x20: Enable SHA_NI instruction set
67 ** API and ABI modifications:
68 gnutls_crypto_register_cipher: Deprecated
69 gnutls_crypto_register_aead_cipher: Deprecated
70 gnutls_crypto_register_digest: Deprecated
71 gnutls_crypto_register_mac: Deprecated
72 gnutls_get_system_config_file: Added
73 gnutls_hash_copy: Added
74 gnutls_hmac_copy: Added
75 GNUTLS_MAC_AES_GMAC_128: Added
76 GNUTLS_MAC_AES_GMAC_192: Added
77 GNUTLS_MAC_AES_CMAC_256: Added
78 GNUTLS_SAN_REGISTERED_ID: Added
81 * Version 3.6.8 (released 2019-05-28)
83 ** libgnutls: Added gnutls_prf_early() function to retrieve early keying
86 ** libgnutls: Added support for AES-XTS cipher (#354)
88 ** libgnutls: Fix calculation of Streebog digests (incorrect carry operation in
91 ** libgnutls: During Diffie-Hellman operations in TLS, verify that the peer's
92 public key is on the right subgroup (y^q=1 mod p), when q is available (under
93 TLS 1.3 and under earlier versions when RFC7919 parameters are used).
95 ** libgnutls: the gnutls_srp_set_server_credentials_function can now be used
96 with the 8192 parameters as well (#995).
98 ** libgnutls: Fixed bug preventing the use of gnutls_pubkey_verify_data2() and
99 gnutls_pubkey_verify_hash2() with the GNUTLS_VERIFY_DISABLE_CA_SIGN flag (#754)
101 ** libgnutls: The priority string option %ALLOW_SMALL_RECORDS was added to allow
102 clients to communicate with the server advertising smaller limits than 512
104 ** libgnutls: Apply STD3 ASCII rules in gnutls_idna_map() to prevent
105 hostname/domain crafting via IDNA conversion (#720)
107 ** certtool: allow the digital signature key usage flag in CA certificates.
108 Previously certtool would ignore this flag for CA certificates even if
111 ** gnutls-cli/serv: added the --keymatexport and --keymatexportsize options.
112 These allow testing the RFC5705 using these tools.
114 ** API and ABI modifications:
115 gnutls_prf_early: Added
116 gnutls_record_set_max_recv_size: Added
117 gnutls_dh_params_import_raw3: Added
118 gnutls_ffdhe_2048_group_q: Added
119 gnutls_ffdhe_3072_group_q: Added
120 gnutls_ffdhe_4096_group_q: Added
121 gnutls_ffdhe_6144_group_q: Added
122 gnutls_ffdhe_8192_group_q: Added
125 * Version 3.6.7 (released 2019-03-27)
127 ** libgnutls, gnutls tools: Every gnutls_free() will automatically set
128 the free'd pointer to NULL. This prevents possible use-after-free and
129 double free issues. Use-after-free will be turned into NULL dereference.
130 The counter-measure does not extend to applications using gnutls_free().
132 ** libgnutls: Fixed a memory corruption (double free) vulnerability in the
133 certificate verification API. Reported by Tavis Ormandy; addressed with
134 the change above. [GNUTLS-SA-2019-03-27, #694]
136 ** libgnutls: Fixed an invalid pointer access via malformed TLS1.3 async messages;
137 Found using tlsfuzzer. [GNUTLS-SA-2019-03-27, #704]
139 ** libgnutls: enforce key usage limitations on certificates more actively.
140 Previously we would enforce it for TLS1.2 protocol, now we enforce it
141 even when TLS1.3 is negotiated, or on client certificates as well. When
142 an inappropriate for TLS1.3 certificate is seen on the credentials structure
143 GnuTLS will disable TLS1.3 support for that session (#690).
145 ** libgnutls: the default number of tickets sent under TLS 1.3 was increased to
146 two. This makes it easier for clients which perform multiple connections
147 to the server to use the tickets sent by a default server.
149 ** libgnutls: enforce the equality of the two signature parameters fields in
150 a certificate. We were already enforcing the signature algorithm, but there
151 was a bug in parameter checking code.
153 ** libgnutls: fixed issue preventing sending and receiving from different
154 threads when false start was enabled (#713).
156 ** libgnutls: the flag GNUTLS_PKCS11_OBJ_FLAG_LOGIN_SO now implies a writable
157 session, as non-writeable security officer sessions are undefined in PKCS#11
160 ** libgnutls: no longer send downgrade sentinel in TLS 1.3.
161 Previously the sentinel value was embedded to early in version
162 negotiation and was sent even on TLS 1.3. It is now sent only when
163 TLS 1.2 or earlier is negotiated (#689).
165 ** gnutls-cli: Added option --logfile to redirect informational messages output.
167 ** API and ABI modifications:
168 No changes since last version.
171 * Version 3.6.6 (released 2019-01-25)
173 ** libgnutls: gnutls_pubkey_import_ecc_raw() was fixed to set the number bits
174 on the public key (#640).
176 ** libgnutls: Added support for raw public-key authentication as defined in RFC7250.
177 Raw public-keys can be negotiated by enabling the corresponding certificate
178 types via the priority strings. The raw public-key mechanism must be explicitly
179 enabled via the GNUTLS_ENABLE_RAWPK init flag (#26, #280).
181 ** libgnutls: When on server or client side we are sending no extensions we do
182 not set an empty extensions field but we rather remove that field competely.
183 This solves a regression since 3.5.x and improves compatibility of the server
184 side with certain clients.
186 ** libgnutls: We no longer mark RSA keys in PKCS#11 tokens as RSA-PSS capable if
187 the CKA_SIGN is not set (#667).
189 ** libgnutls: The priority string option %NO_EXTENSIONS was improved to completely
190 disable extensions at all cases, while providing a functional session. This
191 also implies that when specified, TLS1.3 is disabled.
193 ** libgnutls: GNUTLS_X509_NO_WELL_DEFINED_EXPIRATION was marked as deprecated.
194 The previous definition was non-functional (#609).
196 ** API and ABI modifications:
197 GNUTLS_ENABLE_RAWPK: Added
198 GNUTLS_ENABLE_CERT_TYPE_NEG: Removed (was no-op; replaced by GNUTLS_ENABLE_RAWPK)
199 GNUTLS_X509_NO_WELL_DEFINED_EXPIRATION: Deprecated
200 GNUTLS_PCERT_NO_CERT: Deprecated
203 * Version 3.6.5 (released 2018-12-01)
205 ** libgnutls: Provide the option of transparent re-handshake/reauthentication
206 when the GNUTLS_AUTO_REAUTH flag is specified in gnutls_init() (#571).
208 ** libgnutls: Added support for TLS 1.3 zero round-trip (0-RTT) mode (#127)
210 ** libgnutls: The priority functions will ignore and not enable TLS1.3 if
211 requested with legacy TLS versions enabled but not TLS1.2. That is because
212 if such a priority string is used in the client side (e.g., TLS1.3+TLS1.0 enabled)
213 servers which do not support TLS1.3 will negotiate TLS1.2 which will be
214 rejected by the client as disabled (#621).
216 ** libgnutls: Change RSA decryption to use a new side-channel silent function.
217 This addresses a security issue where memory access patterns as well as timing
218 on the underlying Nettle rsa-decrypt function could lead to new Bleichenbacher
219 attacks. Side-channel resistant code is slower due to the need to mask
220 access and timings. When used in TLS the new functions cause RSA based
221 handshakes to be between 13% and 28% slower on average (Numbers are indicative,
222 the tests where performed on a relatively modern Intel CPU, results vary
223 depending on the CPU and architecture used). This change makes nettle 3.4.1
224 the minimum requirement of gnutls (#630). [CVSS: medium]
226 ** libgnutls: gnutls_priority_init() and friends, allow the CTYPE-OPENPGP keyword
227 in the priority string. It is only accepted as legacy option and is ignored.
229 ** libgnutls: Added support for EdDSA under PKCS#11 (#417)
231 ** libgnutls: Added support for AES-CFB8 cipher (#357)
233 ** libgnutls: Added support for AES-CMAC MAC (#351)
235 ** libgnutls: In two previous versions GNUTLS_CIPHER_GOST28147_CPB/CPC/CPD_CFB ciphers
236 have incorrectly used CryptoPro-A S-BOX instead of proper (CryptoPro-B/-C/-D
237 S-BOXes). They are fixed now.
239 ** libgnutls: Added support for GOST key unmasking and unwrapped GOST private
240 keys parsing, as specified in R 50.1.112-2016.
242 ** gnutls-serv: It applies the default settings when no --priority option is given,
243 using gnutls_set_default_priority().
245 ** p11tool: Fix initialization of security officer's PIN with the --initialize-so-pin
248 ** certtool: Add parameter --no-text that prevents certtool from outputting
249 text before PEM-encoded private key, public key, certificate, CRL or CSR.
251 ** API and ABI modifications:
252 GNUTLS_AUTO_REAUTH: Added
253 GNUTLS_CIPHER_AES_128_CFB8: Added
254 GNUTLS_CIPHER_AES_192_CFB8: Added
255 GNUTLS_CIPHER_AES_256_CFB8: Added
256 GNUTLS_MAC_AES_CMAC_128: Added
257 GNUTLS_MAC_AES_CMAC_256: Added
258 gnutls_record_get_max_early_data_size: Added
259 gnutls_record_send_early_data: Added
260 gnutls_record_recv_early_data: Added
261 gnutls_db_check_entry_expire_time: Added
262 gnutls_anti_replay_set_add_function: Added
263 gnutls_anti_replay_init: Added
264 gnutls_anti_replay_deinit: Added
265 gnutls_anti_replay_set_window: Added
266 gnutls_anti_replay_enable: Added
267 gnutls_privkey_decrypt_data2: Added
270 * Version 3.6.4 (released 2018-09-24)
272 ** libgnutls: Added the final (RFC8446) version numbering of the TLS1.3 protocol.
274 ** libgnutls: Corrected regression since 3.6.3 in the callbacks set with
275 gnutls_certificate_set_retrieve_function() which could not handle the case where
276 no certificates were returned, or the callbacks were set to NULL (see #528).
278 ** libgnutls: gnutls_handshake() on server returns early on handshake when no
279 certificate is presented by client and the gnutls_init() flag GNUTLS_ENABLE_EARLY_START
282 ** libgnutls: Added session ticket key rotation on server side with TOTP.
283 The key set with gnutls_session_ticket_enable_server() is used as a
284 master key to generate time-based keys for tickets. The rotation
285 relates to the gnutls_db_set_cache_expiration() period.
287 ** libgnutls: The 'record size limit' extension is added and preferred to the
288 'max record size' extension when possible.
290 ** libgnutls: Provide a more flexible PKCS#11 search of trust store certificates.
291 This addresses the problem where the CA certificate doesn't have a subject key
292 identifier whereas the end certificates have an authority key identifier (#569)
294 ** libgnutls: gnutls_privkey_export_gost_raw2(), gnutls_privkey_import_gost_raw(),
295 gnutls_pubkey_export_gost_raw2(), gnutls_pubkey_import_gost_raw() import
296 and export GOST parameters in the "native" little endian format used for these
297 curves. This is an intentional incompatible change with 3.6.3.
299 ** libgnutls: Added support for seperately negotiating client and server certificate types
300 as defined in RFC7250. This mechanism must be explicitly enabled via the
301 GNUTLS_ENABLE_CERT_TYPE_NEG flag in gnutls_init().
303 ** gnutls-cli: enable CRL validation on startup (#564)
305 ** API and ABI modifications:
306 GNUTLS_ENABLE_EARLY_START: Added
307 GNUTLS_ENABLE_CERT_TYPE_NEG: Added
308 GNUTLS_TL_FAIL_ON_INVALID_CRL: Added
309 GNUTLS_CERTIFICATE_VERIFY_CRLS: Added
310 gnutls_ctype_target_t: New enumeration
311 gnutls_record_set_max_early_data_size: Added
312 gnutls_certificate_type_get2: Added
313 gnutls_priority_certificate_type_list2: Added
314 gnutls_ffdhe_6144_group_prime: Added
315 gnutls_ffdhe_6144_group_generator: Added
316 gnutls_ffdhe_6144_key_bits: Added
319 * Version 3.6.3 (released 2018-07-16)
321 ** libgnutls: Introduced support for draft-ietf-tls-tls13-28. It includes version
322 negotiation, post handshake authentication, length hiding, multiple OCSP support,
323 consistent ciphersuite support across protocols, hello retry requests, ability
324 to adjust key shares via gnutls_init() flags, certificate authorities extension,
325 and key usage limits. TLS1.3 draft-28 support can be enabled by default if
326 the option --enable-tls13-support is given to configure script.
328 ** libgnutls: Apply compatibility settings for existing applications running with TLS1.2 or
329 earlier and TLS 1.3. When SRP or NULL ciphersuites are specified in priority strings
330 TLS 1.3 is will be disabled. When Anonymous ciphersuites are specified in priority
331 strings, then TLS 1.3 negotiation will be disabled if the session is associated
332 only with an anonymous credentials structure.
334 ** Added support for Russian Public Key Infrastructure according to RFCs 4491/4357/7836.
335 This adds support for using GOST keys for digital signatures and under PKCS#7, PKCS#12,
336 and PKCS#8 standards. In particular added elliptic curves GOST R 34.10-2001 CryptoProA
337 256-bit curve (RFC 4357), GOST R 34.10-2001 CryptoProXchA 256-bit curve (RFC 4357),
338 and GOST R 34.10-2012 TC26-512-A 512-bit curve (RFC 7836).
340 ** Provide a uniform cipher list across supported TLS protocols; the CAMELLIA ciphers
341 as well as ciphers utilizing HMAC-SHA384 and SHA256 have been removed from the default
342 priority strings, as they are undefined under TLS1.3 and they provide no advantage
343 over other options in earlier protocols.
345 ** The SSL 3.0 protocol is disabled on compile-time by default. It can be re-enabled
346 by specifying --enable-ssl3-support on configure script.
348 ** libgnutls: Introduced function to switch the current FIPS140-2 operational
349 mode, i.e., strict vs a more lax mode which will allow certain non FIPS140-2
352 ** libgnutls: Introduced low-level function to assist applications attempting client
353 hello extension parsing, prior to GnuTLS' parsing of the message.
355 ** libgnutls: When exporting an X.509 certificate avoid re-encoding if there are no
356 modifications to the certificate. That prevents DER re-encoding issues with incorrectly
357 encoded certificates, or other DER incompatibilities to affect a TLS session.
360 ** libgnutls: on group exchange honor the %SERVER_PRECEDENCE and select the groups
361 which are preferred by the server. That unfortunately has complicated semantics
362 as TLS1.2 requires specific ordering of the groups based on the ciphersuite ordering,
363 which could make group order unpredictable if TLS1.3 is negotiated.
365 ** Improved counter-measures for TLS CBC record padding. Kenny Paterson, Eyal Ronen
366 and Adi Shamir reported that the existing counter-measures had certain issues and
367 were insufficient when the attacker has additional access to the CPU cache and
368 performs a chosen-plaintext attack. This affected the legacy CBC ciphersuites. [CVSS: medium]
370 ** Introduced the %FORCE_ETM priority string option. This option prevents the negotiation
371 of legacy CBC ciphersuites unless encrypt-then-mac is negotiated.
373 ** libgnutls: gnutls_privkey_import_ext4() was enhanced with the
374 GNUTLS_PRIVKEY_INFO_PK_ALGO_BITS flag.
376 ** libgnutls: gnutls_pkcs11_copy_secret_key, gnutls_pkcs11_copy_x509_privkey2,
377 gnutls_pkcs11_privkey_generate3 will mark objects as sensitive by default
378 unless GNUTLS_PKCS11_OBJ_FLAG_MARK_NOT_SENSITIVE is specified. This is an API
379 change for these functions which make them err towards safety.
381 ** libgnutls: improved aarch64 cpu features detection by using getauxval().
383 ** certtool: It is now possible to specify certificate and serial CRL numbers greater
384 than 2**63-2 as a hex-encoded string both when prompted and in a template file.
385 Default certificate serial numbers are now fully random. Default CRL
386 numbers include more random bits and are larger than in previous GnuTLS versions.
387 Since CRL numbers are required to be monotonic, specify suitable CRL numbers manually
388 if you intend to later downgrade to previous versions as it was not possible
389 to specify large CRL numbers in previous versions of certtool.
391 ** API and ABI modifications:
392 gnutls_fips140_set_mode: Added
393 gnutls_session_key_update: Added
394 gnutls_ext_get_current_msg: Added
396 gnutls_ocsp_status_request_get2: Added
397 gnutls_ocsp_resp_import2: Added
398 gnutls_ocsp_resp_export2: Added
399 gnutls_ocsp_resp_list_import2: Added
400 gnutls_certificate_set_retrieve_function3: Added
401 gnutls_certificate_set_ocsp_status_request_file2: Added
402 gnutls_certificate_set_ocsp_status_request_mem: Added
403 gnutls_certificate_get_ocsp_expiration: Added
404 gnutls_record_send2: Added
405 gnutls_ext_raw_parse: Added
406 gnutls_x509_crt_list_import_url: Added
407 gnutls_pcert_list_import_x509_file: Added
408 gnutls_pkcs11_token_get_ptr: Added
409 gnutls_pkcs11_obj_get_ptr: Added
410 gnutls_session_ticket_send: Added
411 gnutls_aead_cipher_encryptv: Added
412 gnutls_gost_paramset_get_name: Added
413 gnutls_gost_paramset_get_oid: Added
414 gnutls_oid_to_gost_paramset: Added
415 gnutls_decode_gost_rs_value: Added
416 gnutls_encode_gost_rs_value: Added
417 gnutls_pubkey_export_gost_raw2: Added
418 gnutls_pubkey_import_gost_raw: Added
419 gnutls_x509_crt_get_pk_gost_raw: Added
420 gnutls_privkey_export_gost_raw2: Added
421 gnutls_privkey_import_gost_raw: Added
422 gnutls_x509_privkey_export_gost_raw: Added
423 gnutls_x509_privkey_import_gost_raw: Added
424 gnutls_set_default_priority_append: Added
425 gnutls_priority_init2: Added
426 GNUTLS_PRIVKEY_INFO_PK_ALGO_BITS: Added
427 GNUTLS_PKCS11_OBJ_FLAG_MARK_NOT_SENSITIVE: Added
430 * Version 3.6.2 (released 2018-02-16)
432 ** libgnutls: When verifying against a self signed certificate ignore issuer.
433 That is, ignore issuer when checking the issuer's parameters strength, resolving
434 issue #347 which caused self signed certificates to be additionally marked as of
435 insufficient security level.
437 ** libgnutls: Corrected MTU calculation for the CBC ciphersuites. The data
438 MTU calculation now, it correctly accounts for the fixed overhead due to
439 padding (as 1 byte), while at the same time considers the rest of the
440 padding as part of data MTU.
442 ** libgnutls: Address issue of loading of all PKCS#11 modules on startup
443 on systems with a PKCS#11 trust store (as opposed to a file trust store).
444 Introduced a multi-stage initialization which loads the trust modules, and
445 other modules are deferred for the first pure PKCS#11 request.
447 ** libgnutls: The SRP authentication will reject any parameters outside
448 RFC5054. This protects any client from potential MitM due to insecure
449 parameters. That also brings SRP in par with the RFC7919 changes to
452 ** libgnutls: Added the 8192-bit parameters of SRP to the accepted parameters
453 for SRP authentication.
455 ** libgnutls: Addressed issue in the accelerated code affecting interoperability
456 with versions of nettle >= 3.4.
458 ** libgnutls: Addressed issue in the AES-GCM acceleration under aarch64.
460 ** libgnutls: Addressed issue in the AES-CBC acceleration under ssse3 (patch by
463 ** srptool: the --create-conf option no longer includes 1024-bit parameters.
465 ** p11tool: Fixed the deletion of objects in batch mode.
467 ** API and ABI modifications:
468 gnutls_srp_8192_group_generator: Added
469 gnutls_srp_8192_group_prime: Added
472 * Version 3.6.1 (released 2017-10-21)
474 ** libgnutls: Fixed interoperability issue with openssl when safe renegotiation was
475 used. Resolves gitlab issue #259.
477 ** libgnutls: gnutls_x509_crl_sign, gnutls_x509_crt_sign,
478 gnutls_x509_crq_sign, were modified to sign with a better algorithm than
479 SHA1. They will now sign with an algorithm that corresponds to the security
480 level of the signer's key.
482 ** libgnutls: gnutls_x509_*_sign2() functions and gnutls_x509_*_privkey_sign()
483 accept GNUTLS_DIG_UNKNOWN (0) as a hash function option. That will signal
484 the function to auto-detect an appropriate hash algorithm to use.
486 ** libgnutls: Removed support for signature algorithms using SHA2-224 in TLS.
487 TLS 1.3 no longer uses SHA2-224 and it was never a widespread algorithm
488 in TLS 1.2. As such, no reason to keep supporting it.
490 ** libgnutls: Refuse to use client certificates containing disallowed
491 algorithms for a session. That reverts a change on 3.5.5, which allowed
492 a client to use DSA-SHA1 due to his old DSA certificate, without requiring him
493 to enable DSA-SHA1 (and thus make it acceptable for the server's certificate).
494 The previous approach was to allow a smooth move for client infrastructure
495 after the DSA algorithm became disabled by default, and is no longer necessary
496 as DSA is now being universally depracated.
498 ** libgnutls: Refuse to resume a session which had a different SNI advertised. That
499 improves RFC6066 support in server side. Reported by Thomas Klute.
501 ** p11tool: Mark all generated objects as sensitive by default.
503 ** p11tool: added options --sign-params and --hash. This allows testing
504 signature with multiple algorithms, including RSA-PSS.
506 ** API and ABI modifications:
507 No changes since last version.
510 * Version 3.6.0 (released 2017-08-21)
512 ** libgnutls: tlsfuzzer is part of the CI testsuite. This is a TLS testing and
513 fuzzying toolkit, allowing for corner case testing, and ensuring that the
514 behavior of the library will not change across releases.
515 https://github.com/tomato42/tlsfuzzer
517 ** libgnutls: Introduced a lock-free random generator which operates per-thread
518 and eliminates random-generator related bottlenecks in multi-threaded operation.
519 Resolves gitlab issue #141.
520 http://nmav.gnutls.org/2017/03/improving-by-simplifying-gnutls-prng.html
522 ** libgnutls: Replaced the Salsa20 random generator with one based on CHACHA.
523 The goal is to reduce code needed in cache (CHACHA is also used for TLS),
524 and the number of primitives used by the library. That does not affect the
525 AES-DRBG random generator used in FIPS140-2 mode.
527 ** libgnutls: Added support for RSA-PSS key type as well as signatures in
528 certificates, and TLS key exchange. Contributed by Daiki Ueno.
529 RSA-PSS signatures can be generated by RSA-PSS keys and normal RSA keys,
530 but not vice-versa. The feature includes:
531 * RSA-PSS key generation and key handling (in PKCS#8 form)
532 * RSA-PSS key generation and key handling from PKCS#11 (with CKM_RSA_PKCS_PSS mech)
533 * Handling of RSA-PSS subjectPublicKeyInfo parameters, when present
534 in either the private key or certificate.
535 * RSA-PSS signing and verification of PKIX certificates
536 * RSA-PSS signing and verification of TLS 1.2 handshake
537 * RSA-PSS signing and verification of PKCS#7 structures
538 * RSA-PSS and RSA key combinations for TLS credentials. That is, when
539 multiple keys are supplied, RSA-PSS keys are preferred over RSA for RSA-PSS
540 TLS signatures, to contain risks of cross-protocol attacks between the algorithms.
541 * RSA-PSS key conversion to RSA PKCS#1 form (certtool --to-rsa)
542 Note that RSA-PSS signatures with SHA1 are (intentionally) not supported.
544 ** libgnutls: Added support for Ed25519 signing in certificates and TLS key
545 exchange following draft-ietf-tls-rfc4492bis-17. The feature includes:
546 * Ed25519 key generation and key handling (in PKCS#8 form)
547 * Ed25519 signing and verification of PKIX certificates
548 * Ed25519 signing and verification of TLS 1.2 handshake
549 * Ed25519 signing and verification of PKCS#7 structures
551 ** libgnutls: Enabled X25519 key exchange by default, following draft-ietf-tls-rfc4492bis-17.
553 ** libgnutls: Added support for Diffie-Hellman group negotiation following RFC7919.
554 That makes the DH parameters negotiation more robust and less prone to errors
555 due to insecure parameters. Servers are no longer required to specific explicit
556 DH parameters, though if they do these parameters will be used. Group
557 selection can be done via priority strings. The introduced strings are
558 GROUP-ALL, GROUP-FFDHE2048, GROUP-FFDHE3072, GROUP-FFDHE4096 and
559 GROUP-FFDHE8192, as well as the corresponding to curves groups. Note that
560 the 6144 group from RFC7919 is not supported.
562 ** libgnutls: Introduced various sanity checks on certificate import. Refuse
563 to import certificates which have fractional seconds in Time fields, X.509v1
564 certificates which have the unique identifiers set, and certificates with illegal
565 version numbers. All of these are prohibited by RFC5280.
567 ** libgnutls: Introduced gnutls_x509_crt_set_flags(). This function can set flags
568 in the crt structure. The only flag supported at the moment is
569 GNUTLS_X509_CRT_FLAG_IGNORE_SANITY which skips the certificate sanity
572 ** libgnutls: PKIX certificates with unknown critical extensions are rejected
573 on verification with status GNUTLS_CERT_UNKNOWN_CRIT_EXTENSIONS. This
574 behavior can be overridden by providing the flag GNUTLS_VERIFY_IGNORE_UNKNOWN_CRIT_EXTENSIONS
575 to verification functions. Resolves gitlab issue #177.
577 ** libgnutls: Refuse to generate a certificate with an illegal version, or an
578 illegal serial number. That is, gnutls_x509_crt_set_version() and
579 gnutls_x509_crt_set_serial(), will fail on input considered to be invalid
582 ** libgnutls: Calls to gnutls_record_send() and gnutls_record_recv()
583 prior to handshake being complete are now refused. Addresses gitlab issue #158.
585 ** libgnutls: Added support for PKCS#12 files with no salt (zero length) in their
586 password encoding, and PKCS#12 files using SHA384 and SHA512 as MAC.
588 ** libgnutls: Exported functions to encode and decode DSA and ECDSA r,s values.
590 ** libgnutls: Added new callback setting function to gnutls_privkey_t for external
591 keys. The new function (gnutls_privkey_import_ext4), allows signing in addition
592 to previous algorithms (RSA PKCS#1 1.5, DSA, ECDSA), with RSA-PSS and Ed25519
595 ** libgnutls: Introduced the %VERIFY_ALLOW_BROKEN and %VERIFY_ALLOW_SIGN_WITH_SHA1
596 priority string options. These allows enabling all broken and SHA1-based signature
597 algorithms in certificate verification, respectively.
599 ** libgnutls: 3DES-CBC is no longer included in the default priorities
600 list. It has to be explicitly enabled, e.g., with a string like
603 ** libgnutls: SHA1 was marked as insecure for signing certificates. Verification
604 of certificates signed with SHA1 is now considered insecure and will
605 fail, unless flags intended to enable broken algorithms are set. Other uses
606 of SHA1 are still allowed. This can be reverted on compile time with the configure
607 flag --enable-sha1-support.
609 ** libgnutls: RIPEMD160 was marked as insecure for certificate signatures. Verification
610 of certificates signed with RIPEMD160 hash algorithm is now considered insecure and
611 will fail, unless flags intended to enable broken algorithms are set.
613 ** libgnutls: No longer enable SECP192R1 and SECP224R1 by default on TLS handshakes.
614 These curves were rarely used for that purpose, provide no advantage over
615 x25519 and were deprecated by TLS 1.3.
617 ** libgnutls: Removed support for DEFLATE, or any other compression method.
619 ** libgnutls: OpenPGP authentication was removed; the resulting library is ABI
620 compatible, with the openpgp related functions being stubs that fail
623 ** libgnutls: Removed support for libidn (i.e., IDNA2003); gnutls can now be compiled
624 only with libidn2 which provides IDNA2008.
626 ** certtool: The option '--load-ca-certificate' can now accept PKCS#11
627 URLs in addition to files.
629 ** certtool: The option '--load-crl' can now be used when generating PKCS#12
630 files (i.e., in conjunction with '--to-p12' option).
632 ** certtool: Keys with provable RSA and DSA parameters are now only read and
633 exported from PKCS#8 form, following draft-mavrogiannopoulos-pkcs8-validated-parameters-00.txt.
634 This removes support for the previous a non-standard key format.
636 ** certtool: Added support for generating, printing and handling RSA-PSS and
637 Ed25519 keys and certificates.
639 ** certtool: the parameters --rsa, --dsa and --ecdsa to --generate-privkey are now
640 deprecated, replaced by the --key-type option.
642 ** p11tool: The --generate-rsa, --generate-ecc and --generate-dsa options were
643 replaced by the --generate-privkey option.
645 ** psktool: Generate 256-bit keys by default.
647 ** gnutls-server: Increase request buffer size to 16kb, and added the --alpn and
648 --alpn-fatal options, allowing testing of ALPN negotiation.
650 ** API and ABI modifications:
651 gnutls_encode_rs_value: Added
652 gnutls_decode_rs_value: Added
653 gnutls_base64_encode2: Added
654 gnutls_base64_decode2: Added
655 gnutls_x509_crt_set_flags: Added

670 gnutls_x509_spki_set_pk_algorithm: Added
671 gnutls_x509_spki_get_digest_algorithm: Added
672 gnutls_x509_spki_set_digest_algorithm: Added
673 gnutls_x509_spki_get_salt_size: Added
674 gnutls_x509_spki_set_salt_size: Added
675 gnutls_x509_crt_set_spki: Added

688 GNUTLS_X509_CRT_FLAG_IGNORE_SANITY: Added
689 GNUTLS_CERT_UNKNOWN_CRIT_EXTENSIONS: Added
690 GNUTLS_VERIFY_ALLOW_SIGN_WITH_SHA1: Added
691 GNUTLS_VERIFY_DO_NOT_ALLOW_IP_MATCHES: Added
692 GNUTLS_VERIFY_IGNORE_UNKNOWN_CRIT_EXTENSIONS: Added
693 GNUTLS_SFLAGS_RFC7919: Added
696 * Version 3.5.7 (released 2016-12-8)
698 ** libgnutls: Include CHACHA20-POLY1305 ciphersuites in the SECURE128
699 and SECURE256 priority strings.
701 ** libgnutls: Require libtasn1 4.9; this ensures gnutls will correctly
702 operate with OIDs which have elements that exceed 2^32.
704 ** libgnutls: The DN decoding functions output the traditional DN format
705 rather than the strict RFC4514 compliant textual DN. This reverts the
706 3.5.6 introduced change, and allows applications which depended on the
707 previous format to continue to function. Introduced new functions which
708 output the strict format by default, and can revert to the old one using
711 ** libgnutls: Improved TPM key handling. Check authorization requirements
712 prior to using a key and fix issue on loop for PIN input. Patches by
715 ** libgnutls: In all functions accepting UTF-8 passwords, ensure that
716 passwords are normalized according to RFC7613. When invalid UTF-8
717 passwords are detected, they are only tolerated for decryption.
718 This introduces a libunistring dependency on GnuTLS. A version of
719 libunistring is included in the library for the platforms that do
720 not ship it; it can be used with the '--with-included-unistring'
721 option to configure script.
723 ** libgnutls: When setting a subject alternative name in a certificate
724 which is in UTF-8 format, it will transparently be converted to IDNA form
727 ** libgnutls: GNUTLS_CRT_PRINT_ONELINE flag on gnutls_x509_crt_print()
728 will print the SHA256 key-ID instead of a certificate fingerprint.
730 ** libgnutls: enhance the PKCS#7 verification capabilities. In the case
731 signers that are not discoverable using the trust list or input, use
732 the stored list as pool to generate a trusted chain to the signer.
734 ** libgnutls: Improved MTU calculation precision for the CBC ciphersuites
737 ** libgnutls: [added missing news entry since 3.5.0]
738 No longer tolerate certificate key usage violations for
739 TLS signature verification, and decryption. That is GnuTLS will fail
740 to connect to servers which incorrectly use a restricted to signing certificate
741 for decryption, or vice-versa. This reverts the lax behavior introduced
742 in 3.1.0, due to several such broken servers being available. The %COMPAT
743 priority keyword can be used to work-around connecting on these servers.
745 ** certtool: When exporting a CRQ in DER format ensure no text data are
746 intermixed. Patch by Dmitry Eremin-Solenikov.
748 ** certtool: Include the SHA-256 variant of key ID in --certificate-info
751 ** p11tool: Introduced the --initialize-pin and --initialize-so-pin
754 ** API and ABI modifications:
755 gnutls_utf8_password_normalize: Added
756 gnutls_ocsp_resp_get_responder2: Added
757 gnutls_x509_crt_get_issuer_dn3: Added
758 gnutls_x509_crt_get_dn3: Added
759 gnutls_x509_rdn_get2: Added
760 gnutls_x509_dn_get_str2: Added
761 gnutls_x509_crl_get_issuer_dn3: Added
762 gnutls_x509_crq_get_dn3: Added
765 * Version 3.5.6 (released 2016-11-04)
767 ** libgnutls: Enhanced the PKCS#7 parser to allow decoding old
768 (pre-rfc5652) structures with arbitrary encapsulated content.
770 ** libgnutls: Introduced a function group to set known DH parameters
771 using groups from RFC7919.
773 ** libgnutls: Added more strict RFC4514 textual DN encoding and decoding.
774 Now the generated textual DN is in reverse order according to RFC4514,
775 and functions which generate a DN from strings such gnutls_x509_crt_set_*dn()
776 set the expected DN (reverse of the provided string).
778 ** libgnutls: Introduced time and constraints checks in the end certificate
779 in the gnutls_x509_crt_verify_data2() and gnutls_pkcs7_verify_direct()
782 ** libgnutls: Set limits on the maximum number of alerts handled. That is,
783 applications using gnutls could be tricked into an busy loop if the
784 peer sends continuously alert messages. Applications which set a maximum
785 handshake time (via gnutls_handshake_set_timeout) will eventually recover
786 but others may remain in a busy loops indefinitely. This is related but
787 not identical to CVE-2016-8610, due to the difference in alert handling
788 of the libraries (gnutls delegates that handling to applications).
790 ** libgnutls: Reverted the change which made the gnutls_certificate_set_*key*
791 functions return an index (introduced in 3.5.5), to avoid affecting programs
792 which explicitly check success of the function as equality to zero. In order
793 for these functions to return an index an explicit call to gnutls_certificate_set_flags
794 with the GNUTLS_CERTIFICATE_API_V2 flag is now required.
796 ** libgnutls: Reverted the behavior of sending a status request extension even
797 without a response (introduced in 3.5.5). That is, we no longer reply to a
798 client's hello with a status request, with a status request extension. Although
799 that behavior is legal, it creates incompatibility issues with releases in
800 the gnutls 3.3.x branch.
802 ** libgnutls: Delayed the initialization of the random generator at
803 the first call of gnutls_rnd(). This allows applications to load
804 on systems which getrandom() would block, without blocking until
805 real random data are needed.
807 ** certtool: --get-dh-params will output parameters from the RFC7919
810 ** p11tool: improvements in --initialize option.
812 ** API and ABI modifications:
813 GNUTLS_CERTIFICATE_API_V2: Added
814 GNUTLS_NO_TICKETS: Added
815 gnutls_pkcs7_get_embedded_data_oid: Added
816 gnutls_anon_set_server_known_dh_params: Added
817 gnutls_certificate_set_known_dh_params: Added
818 gnutls_psk_set_server_known_dh_params: Added
819 gnutls_x509_crt_check_key_purpose: Added
822 * Version 3.5.5 (released 2016-10-09)
824 ** libgnutls: enhanced gnutls_certificate_set_ocsp_status_request_file()
825 to allow importing multiple OCSP request files, one for each chain
828 ** libgnutls: The gnutls_certificate_set_key* functions return an
829 index of the added chain. That index can be used either with
830 gnutls_certificate_set_ocsp_status_request_file(), or with
831 gnutls_certificate_get_crt_raw() and friends.
833 ** libgnutls: Added SHA*, AES-GCM, AES-CCM and AES-CBC optimized implementations
834 for the aarch64 architecture. Uses Andy Polyakov's assembly code.
836 ** libgnutls: Ensure proper cleanups on gnutls_certificate_set_*key()
837 failures due to key mismatch. This prevents leaks or double freeing
840 ** libgnutls: Increased the maximum size of the handshake message hash.
841 This will allow the library to cope better with larger packets, as
842 the ones offered by current TLS 1.3 drafts.
844 ** libgnutls: Allow to use client certificates despite them containing
845 disallowed algorithms for a session. That allows for example a client
846 to use DSA-SHA1 due to his old DSA certificate, without requiring him
847 to enable DSA-SHA1 (and thus make it acceptable for the server's certificate).
849 ** libgnutls: Reverted AESNI code on x86 to earlier version as the
850 latest version was creating position depending code. Added checks
851 in the CI to detect position depending code early.
853 ** guile: Update code to the I/O port API of Guile >= 2.1.4
854 This makes sure the GnuTLS bindings will work with the forthcoming 2.2
855 stable series of Guile, of which 2.1 is a preview.
857 ** API and ABI modifications:
858 gnutls_certificate_set_ocsp_status_request_function2: Added
859 gnutls_session_ext_register: Added
860 gnutls_session_supplemental_register: Added
861 GNUTLS_E_PK_INVALID_PUBKEY: Added
862 GNUTLS_E_PK_INVALID_PRIVKEY: Added
865 * Version 3.5.4 (released 2016-09-08)
867 ** libgnutls: Corrected the comparison of the serial size in OCSP response.
868 Previously the OCSP certificate check wouldn't verify the serial length
869 and could succeed in cases it shouldn't (GNUTLS-SA-2016-3).
870 Reported by Stefan Buehler.
872 ** libgnutls: Added support for IP name constraints. Patch by Martin Ukrop.
874 ** libgnutls: Added support of PKCS#8 file decryption using DES-CBC-MD5. This
875 is added to allow decryption of PKCS #8 private keys from openssl prior to 1.1.0.
877 ** libgnutls: Added support for decrypting PKCS#8 files which use HMAC-SHA256
878 as PRF. This allow decrypting PKCS #8 private keys generated with openssl 1.1.0.
880 ** libgnutls: Added support for internationalized passwords in PKCS#12 files.
881 Previous versions would only encrypt or decrypt using passwords from the ASCII
884 ** libgnutls: Addressed issue with PKCS#11 signature generation on ECDSA
885 keys. The signature is now written as unsigned integers into the DSASignatureValue
886 structure. Previously signed integers could be written depending on what
887 the underlying module would produce. Addresses #122.
889 ** gnutls-cli: Fixed starttls regression from 3.5.3.
891 ** API and ABI modifications:
892 GNUTLS_E_MALFORMED_CIDR: Added
893 gnutls_x509_cidr_to_rfc5280: Added
894 gnutls_oid_to_mac: Added
897 * Version 3.5.3 (released 2016-08-09)
899 ** libgnutls: Added support for TCP fast open (RFC7413), allowing
900 to reduce by one round-trip the handshake process. Based on proposal and
901 patch by Tim Ruehsen.
903 ** libgnutls: Adopted a simpler with less memory requirements DTLS sliding
904 window implementation. Based on Fridolin Pokorny's implementation for
907 ** libgnutls: Use getrandom where available via the syscall interface.
908 This works around an issue of not-using getrandom even if it exists
909 since glibc doesn't declare such function.
911 ** libgnutls: Fixed DNS name constraints checking in the case of empty
912 intersection of domain names in the chain. Report and fix by Martin Ukrop.
914 ** libgnutls: Fixed name constraints checking in the case of chains
915 where the higher level certificates contained different types of
916 constraints than the ones present in the lower intermediate CAs.
917 Report and fix by Martin Ukrop.
919 ** libgnutls: Dropped support for the EGD random generator.
921 ** libgnutls: Allow the decoding of raw elements (starting with #)
922 in RFC4514 DN string decoding.
924 ** libgnutls: Fixes in gnutls_x509_crt_list_import2, which was
925 ignoring flags if all certificates in the list fit within the
926 initially allocated memory. Patch by Tim Kosse.
928 ** libgnutls: Corrected issue which made gnutls_certificate_get_x509_crt()
929 to return invalid pointers when returned more than a single certificate.
930 Report and fix by Stefan Sørensen.
932 ** libgnutls: Fix gnutls_pkcs12_simple_parse to always extract the complete chain,
933 even when the extra_certs was non-null. Report and fix by Stefan Sørensen.
935 ** certtool: Added the "add_extension" and "add_critical_extension"
936 template options. This allows specifying arbitrary extensions into
937 certificates and certificate requests.
939 ** gnutls-cli: Added the --fastopen option.
941 ** API and ABI modifications:
942 GNUTLS_E_UNAVAILABLE_DURING_HANDSHAKE: Added
943 gnutls_x509_crq_set_extension_by_oid: Added
944 gnutls_x509_dn_set_str: Added
945 gnutls_transport_set_fastopen: Added
948 * Version 3.5.2 (released 2016-07-06)
950 ** libgnutls: Address issue when utilizing the p11-kit trust store
951 for certificate verification (GNUTLS-SA-2016-2).
953 ** libgnutls: Fixed DTLS handshake packet reconstruction. Reported by
956 ** libgnutls: Fixed issues with PKCS#11 reading of sensitive objects
957 from SafeNet Network HSM. Reported by Anthony Alba in #108.
959 ** libgnutls: Corrected the writing of PKCS#11 CKA_SERIAL_NUMBER. Report
960 and fix by Stanislav Židek.
962 ** libgnutls: Added AES-GCM optimizations using the AVX and MOVBE
963 instructions. Uses Andy Polyakov's assembly code.
965 ** API and ABI modifications:
966 No changes since last version.
969 * Version 3.5.1 (released 2016-06-14)
971 ** libgnutls: The SSL 3.0 protocol support can completely be removed
972 using a compile time option. The configure option is --disable-ssl3-support.
974 ** libgnutls: The SSL 2.0 client hello support can completely be removed
975 using a compile time option. The configure option is --disable-ssl2-support.
977 ** libgnutls: Added support for OCSP Must staple PKIX extension. That is,
978 implemented the RFC7633 TLSFeature for OCSP status request extension.
979 Feature implemented by Tim Kosse.
981 ** libgnutls: More strict OCSP staple verification. That is, no longer
982 ignore invalid or too old OCSP staples. The previous behavior was
983 to rely on application use gnutls_ocsp_status_request_is_checked(),
984 while the new behavior is to include OCSP verification by default
985 and set the GNUTLS_CERT_INVALID_OCSP_STATUS verification flag on error.
987 ** libgnutls: Treat CA certificates with the "Server Gated Cryptography" key
988 purpose OIDs equivalent to having the GNUTLS_KP_TLS_WWW_SERVER OID. This
989 improves interoperability with several old intermediate CA certificates
990 carrying these legacy OIDs.
992 ** libgnutls: Re-read the system wide priority file when needed. Patch by
995 ** libgnutls: Allow for fallback in system-specific initial keywords
996 (prefixed with '@'). That allows to specify a keyword such as
997 "@KEYWORD1,KEYWORD2" which will use the first available of these
998 two keywords. Patch by Daniel P. Berrange.
1000 ** libgnutls: The SSLKEYLOGFILE environment variable can be used to log
1001 session keys. These session keys are compatible with the NSS Key Log
1002 Format and can be used to decrypt the session for debugging using
1005 ** API and ABI modifications:
1006 GNUTLS_CERT_INVALID_OCSP_STATUS: Added
1007 gnutls_x509_crt_set_crq_extension_by_oid: Added

1018 gnutls_ext_get_name: Added
1021 * Version 3.5.0 (released 2016-05-09)
1023 ** libgnutls: Added SHA3 based signing algorithms for DSA, RSA and ECDSA,
1024 based on https://csrc.nist.gov/groups/ST/crypto_apps_infra/csor/algorithms.html
1026 ** libgnutls: Added support for curve X25519 (RFC 7748, draft-ietf-tls-rfc4492bis-07).
1027 This curve is disabled by default as it is still on specification status. It
1028 can be enabled using the priority string modifier +CURVE-X25519.
1030 ** libgnutls: Added support for TLS false start (draft-ietf-tls-falsestart-01)
1031 by introducing gnutls_init() flag GNUTLS_ENABLE_FALSE_START (#73).
1033 ** libgnutls: Added new APIs to access the FIPS186-4 (Shawe-Taylor based) provable
1034 RSA and DSA parameter generation from a seed.
1036 ** libgnutls: The CHACHA20-POLY1305 ciphersuite is enabled by default. This
1037 cipher is prioritized after AES-GCM.
1039 ** libgnutls: On a rehandshake ensure that the certificate of the peer or
1040 its username remains the same as in previous handshakes. That is to protect
1041 applications which do not check user credentials on rehandshakes. The
1042 threat to address depends on the application protocol. Primarily it
1043 protects against applications which authenticate the peer initially and
1044 perform accounting using the session's information, from being misled
1045 by a rehandshake which switches the peer's identity. Applications can
1046 disable this protection by using the %GNUTLS_ALLOW_ID_CHANGE flag in
1049 ** libgnutls: No longer tolerate certificate key usage violations for
1050 TLS signature verification, and decryption. That is GnuTLS will fail
1051 to connect to servers which incorrectly use a restricted to signing certificate
1052 for decryption, or vice-versa. This reverts the lax behavior introduced
1053 in 3.1.0, due to several such broken servers being available. The %COMPAT
1054 priority keyword can be used to work-around connecting on these servers.
1056 ** libgnutls: Be strict in TLS extension decoding. That is, do not tolerate
1057 parsing errors in the extensions field and treat it as a typical Hello
1058 message structure. Reported by Hubert Kario (#40).
1060 ** libgnutls: Old and unsupported version numbers in client hellos are
1061 rejected with a "protocol_version" alert message. Reported by Hubert
1064 ** libgnutls: Lifted the limitation of calling the gnutls_session_get_data*()
1065 functions, only on non-resumed sessions. This brings the API in par with
1068 ** libgnutls: Follow RFC5280 strictly in name constraints computation. The
1069 permitted subtrees is intersected with any previous values. Report and
1070 patch by Daiki Ueno.
1072 ** libgnutls: Enforce the RFC 7627 (extended master secret) requirements on
1073 session resumption. Reported by Hubert Kario (#69).
1075 ** libgnutls: Consider the max-record TLS extension even when under DTLS.
1076 Reported by Peter Dettman (#61).
1078 ** libgnutls: Replaced writev() system call with sendmsg().
1080 ** libgnutls: Replaced select() system call with poll() on POSIX systems.
1082 ** libgnutls: Preload the system priority file on library load. This allows
1083 applications that chroot() to also use the system priorities.
1085 ** libgnutls: Applications are allowed to override the built-in key and
1088 ** libgnutls: The gnutls.h header marks constant and pure functions explictly.
1090 ** certtool: Added the ability to sign certificates using SHA3.
1092 ** certtool: Added the --provable and --verify-allow-broken options.
1094 ** gnutls-cli: The --dane option will cause verification failure if gnutls is not
1095 compiled with DANE support.
1097 ** crywrap: The tool was unbundled from gnutls' distribution. It can be found at
1098 https://github.com/nmav/crywrap
1100 ** guile: .go files are now built and installed
1102 ** guile: Fix compatibility issue of the test suite with Guile 2.1
1104 ** guile: When --with-guile-site-dir is passed, modules are installed in a
1105 versioned directory, typically $(datadir)/guile/site/2.0
1107 ** guile: Tests no longer leave zombie processes behind

1139 * Version 3.4.3 (released 2015-07-12)
1141 ** libgnutls: Follow closely RFC5280 recommendations and use UTCTime for
1142 dates prior to 2050.
1144 ** libgnutls: Force 16-byte alignment to all input to ciphers (previously it
1145 was done only when cryptodev was enabled).
1147 ** libgnutls: Removed support for pthread_atfork() as it has undefined
1148 semantics when used with dlopen(), and may lead to a crash.
1150 ** libgnutls: corrected failure when importing plain files
1151 with gnutls_x509_privkey_import2(), and a password was provided.
1153 ** libgnutls: Don't reject certificates if a CA has the URI or IP address
1154 name constraints, and the end certificate doesn't have an IP address
1157 ** libgnutls: set and read the hint in DHE-PSK and ECDHE-PSK ciphersuites.
1159 ** p11tool: Added --list-token-urls option, and print the token module name
1162 ** API and ABI modifications:

1171 gnutls_oid_to_ecc_curve: Added
1172 gnutls_pkcs7_get_signature_count: Added
1175 * Version 3.4.2 (released 2015-06-16)
1177 ** libgnutls: DTLS blocking API is more robust against infinite blocking,
1178 and will notify of more possible timeouts.
1180 ** libgnutls: corrected regression with Camellia-256-GCM cipher. Reported
1181 by Manuel Pegourie-Gonnard.
1183 ** libgnutls: Introduced the GNUTLS_NO_SIGNAL flag to gnutls_init(). That
1184 allows to disable SIGPIPE for writes done within gnutls.
1186 ** libgnutls: Enhanced the PKCS #7 API to allow signing and verification
1187 of structures. API moved to gnutls/pkcs7.h header.
1189 ** certtool: Added options to generate PKCS #7 bundles and signed
1192 ** API and ABI modifications:
1193 gnutls_x509_dn_get_str: Added

1206 gnutls_pkcs7_get_attr: Added
1207 gnutls_pkcs7_print: Added
1210 * Version 3.4.1 (released 2015-05-03)
1212 ** libgnutls: gnutls_certificate_get_ours: will return the certificate even
1213 if a callback was used to send it.
1215 ** libgnutls: Check for invalid length in the X.509 version field. Without
1216 the check certificates with invalid length would be detected as having an
1217 arbitrary version. Reported by Hanno Böck.
1219 ** libgnutls: Handle DNS name constraints with a leading dot. Patch by
1222 ** libgnutls: Updated system-keys support for windows to compile in more
1223 versions of mingw. Patch by Tim Kosse.
1225 ** libgnutls: Fix for MD5 downgrade in TLS 1.2 signatures. Reported by
1226 Karthikeyan Bhargavan [GNUTLS-SA-2015-2].
1228 ** libgnutls: Reverted: The gnutls_handshake() process will enforce a timeout
1229 by default. That caused issues with non-blocking programs.
1231 ** certtool: It can generate SHA256 key IDs.
1233 ** gnutls-cli: fixed crash in --benchmark-ciphers. Reported by James Cloos.
1235 ** configure: re-enabled the --enable-local-libopts flag
1237 ** API and ABI modifications:
1238 gnutls_x509_crt_get_pk_ecc_raw: Added
1241 * Version 3.4.0 (released 2015-04-08)
1243 ** libgnutls: Added support for AES-CCM and AES-CCM-8 (RFC6655 and RFC7251)
1244 ciphersuites. The former are enabled by default, the latter need to be
1245 explicitly enabled, since they reduce the overall security level.
1247 ** libgnutls: Added support for Chacha20-Poly1305 ciphersuites following
1248 draft-mavrogiannopoulos-chacha-tls-05 and draft-irtf-cfrg-chacha20-poly1305-10.
1249 That is currently provided as technology preview and is not enabled by
1250 default, since there are no assigned ciphersuite points by IETF and there
1251 is no guarrantee of compatibility between draft versions. The ciphersuite
1252 priority string to enable it is "+CHACHA20-POLY1305".
1254 ** libgnutls: Added support for encrypt-then-authenticate in CBC
1255 ciphersuites (RFC7366 -taking into account its errata text). This is
1256 enabled by default and can be disabled using the %NO_ETM priority
1259 ** libgnutls: Added support for the extended master secret
1260 (triple-handshake fix) following draft-ietf-tls-session-hash-02.
1262 ** libgnutls: Added a new simple and hard to misuse AEAD API (crypto.h).
1264 ** libgnutls: SSL 3.0 is no longer included in the default priorities
1265 list. It has to be explicitly enabled, e.g., with a string like
1266 "NORMAL:+VERS-SSL3.0".
1268 ** libgnutls: ARCFOUR (RC4) is no longer included in the default priorities
1269 list. It has to be explicitly enabled, e.g., with a string like
1270 "NORMAL:+ARCFOUR-128".
1272 ** libgnutls: DSA signatures and DHE-DSS are no longer included in the
1273 default priorities list. They have to be explicitly enabled, e.g., with
1274 a string like "NORMAL:+DHE-DSS:+SIGN-DSA-SHA256:+SIGN-DSA-SHA1". The
1275 DSA ciphersuites were dropped because they had no deployment at all
1276 on the internet, to justify their inclusion.
1278 ** libgnutls: The priority string EXPORT was completely removed. The string
1279 was already defunc as support for the EXPORT ciphersuites was removed in
1282 ** libgnutls: Added API to utilize system specific private keys in
1283 "gnutls/system-keys.h". It is currently provided as technology preview
1284 and is restricted to windows CNG keys.
1286 ** libgnutls: gnutls_x509_crt_check_hostname() and friends will use
1287 RFC6125 comparison of hostnames. That introduces a dependency on libidn.
1289 ** libgnutls: Depend on p11-kit 0.23.1 to comply with the final
1290 PKCS #11 URLs draft (draft-pechanec-pkcs11uri-21).
1292 ** libgnutls: Depend on nettle 3.1.
1294 ** libgnutls: Use getrandom() or getentropy() when available. That
1295 avoids the complexity of file descriptor handling and issues with
1296 applications closing all open file descriptors on startup.
1298 ** libgnutls: Use pthread_atfork() to detect fork when available.
1300 ** libgnutls: If a key purpose (extended key usage) is specified for verification,
1301 it is applied into intermediate certificates. The verification result
1302 GNUTLS_CERT_PURPOSE_MISMATCH is also introduced.
1304 ** libgnutls: When gnutls_certificate_set_x509_key_file2() is used in
1305 combination with PKCS #11, or TPM URLs, it will utilize the provided
1306 password as PIN if required. That removes the requirement for the
1307 application to set a callback for PINs in that case.
1309 ** libgnutls: priority strings VERS-TLS-ALL and VERS-DTLS-ALL are
1310 restricted to the corresponding protocols only, and the VERS-ALL
1311 string is introduced to catch all possible protocols.
1313 ** libgnutls: Added helper functions to obtain information on PKCS #8
1316 ** libgnutls: Certificate chains which are provided to gnutls_certificate_credentials_t
1317 will automatically be sorted instead of failing with GNUTLS_E_CERTIFICATE_LIST_UNSORTED.
1319 ** libgnutls: Added functions to export and set the record state. That
1320 allows for gnutls_record_send() and recv() to be offloaded (to kernel,
1321 hardware or any other subsystem).
1323 ** libgnutls: Added the ability to register application specific URL
1324 types, which express certificates and keys using gnutls_register_custom_url().
1326 ** libgnutls: Added API to override existing ciphers, digests and MACs, e.g.,
1327 to override AES-GCM using a system-specific accelerator. That is, (crypto.h)
1328 gnutls_crypto_register_cipher(), gnutls_crypto_register_aead_cipher(),
1329 gnutls_crypto_register_mac(), and gnutls_crypto_register_digest().
1331 ** libgnutls: Added gnutls_ext_register() to register custom extensions.
1332 Contributed by Thierry Quemerais.
1334 ** libgnutls: Added gnutls_supplemental_register() to register custom
1335 supplemental data handshake messages. Contributed by Thierry Quemerais.
1337 ** libgnutls-openssl: it is no longer built by default.
1340 ** certtool: Added --p8-info option, which will print PKCS #8 information
1341 even if the password is not available.
1343 ** certtool: --key-info option will print PKCS #8 encryption information
1346 ** certtool: Added the --key-id and --fingerprint options.
1348 ** certtool: Added the --verify-hostname, --verify-email and --verify-purpose
1349 options to be used in certificate chain verification, to simulate verification
1350 for specific hostname and key purpose (extended key usage).
1352 ** certtool: --p12-info option will print PKCS #12 MAC and cipher information
1355 ** certtool: it will print the A-label (ACE) names in addition to UTF-8.
1357 ** p11tool: added options --set-id and --set-label.
1359 ** gnutls-cli: added options --priority-list and --save-cert.
1361 ** guile: Deprecated priority API has been removed. The old priority API,
1362 which had been deprecated for some time, is now gone; use 'set-session-priorities!'
1365 ** guile: Remove RSA parameters and related procedures. This API had been
1368 ** guile: Fix compilation on MinGW. Previously only the static version of the
1369 'guile-gnutls-v-2' library would be built, preventing dynamic loading from Guile.

1477 pkcs1-export-rsa-parameters: Removed
1481 * Version 3.3.6 (released 2014-07-23)
1483 ** libgnutls: Use inet_ntop to print IP addresses when available
1485 ** libgnutls: gnutls_x509_crt_check_hostname and friends will also check
1486 IP addresses, and match documented behavior. Reported by David Woodhouse.
1488 ** libgnutls: DSA key generation in FIPS140-2 mode doesn't allow 1024
1491 ** libgnutls: fixed issue in gnutls_pkcs11_reinit() which prevented tokens
1492 being usable after a reinitialization.
1494 ** libgnutls: fixed PKCS #11 private key operations after a fork.
1496 ** libgnutls: fixed PKCS #11 ECDSA key generation.
1498 ** libgnutls: The GNUTLS_CPUID_OVERRIDE environment variable can be used to
1499 explicitly enable/disable the use of certain CPU capabilities. Note that CPU
1500 detection cannot be overridden, i.e., VIA options cannot be enabled on an Intel
1501 CPU. The currently available options are:
1502 0x1: Disable all run-time detected optimizations
1506 0x100000: Enable VIA padlock
1507 0x200000: Enable VIA PHE
1508 0x400000: Enable VIA PHE SHA512
1510 ** libdane: added dane_query_to_raw_tlsa(); patch by Simon Arlott.
1512 ** p11tool: use GNUTLS_SO_PIN to read the security officer's PIN if set.
1514 ** p11tool: ask for label when one isn't provided.
1516 ** p11tool: added --batch parameter to disable any interactivity.
1518 ** p11tool: will not implicitly enable so-login for certain types of
1519 objects. That avoids issues with tokens that require different login
1522 ** certtool/p11tool: Added the --curve parameter which allows to explicitly
1523 specify the curve to use.
1525 ** API and ABI modifications:
1526 gnutls_certificate_set_x509_trust_dir: Added
1527 gnutls_x509_trust_list_add_trust_dir: Added
1530 * Version 3.3.5 (released 2014-06-26)
1532 ** libgnutls: Added gnutls_record_recv_packet() and gnutls_packet_deinit().
1533 These functions provide a variant of gnutls_record_recv() that avoids
1534 the final memcpy of data.
1536 ** libgnutls: gnutls_x509_crl_iter_crt_serial() was added as a
1537 faster variant of gnutls_x509_crl_get_crt_serial() when coping with
1538 very large structures.
1540 ** libgnutls: When the decoding of a printable DN element fails, then treat
1541 it as unknown and print its hex value rather than failing. That works around
1542 an issue in a TURKTRST root certificate which improperly encodes the
1543 X520countryName element.
1545 ** libgnutls: gnutls_x509_trust_list_add_trust_file() will return the number
1546 of certificates present in a PKCS #11 token when loading it.
1548 ** libgnutls: Allow the post client hello callback to put the handshake on
1549 hold, by returning GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED.
1551 ** certtool: option --to-p12 will now consider --load-ca-certificate
1553 ** certtol: Added option to specify the PKCS #12 friendly name on command
1556 ** p11tool: Allow marking a certificate copied to a token as a CA.
1558 ** API and ABI modifications:
1559 GNUTLS_PKCS11_OBJ_FLAG_MARK_CA: Added
1560 gnutls_x509_crl_iter_deinit: Added
1561 gnutls_x509_crl_iter_crt_serial: Added
1562 gnutls_record_recv_packet: Added
1563 gnutls_packet_deinit: Added
1564 gnutls_packet_get: Added
1567 * Version 3.3.4 (released 2014-05-31)
1569 ** libgnutls: Updated Andy Polyakov's assembly code. That prevents a
1570 crash on certain CPUs.
1572 ** API and ABI modifications:
1573 No changes since last version.
1576 * Version 3.3.3 (released 2014-05-30)
1578 ** libgnutls: Eliminated memory corruption issue in Server Hello parsing.
1579 Issue reported by Joonas Kuorilehto of Codenomicon.
1581 ** libgnutls: gnutls_global_set_mutex() was modified to operate with the
1582 new initialization process.
1584 ** libgnutls: Increased the maximum certificate size buffer
1585 in the PKCS #11 subsystem.
1587 ** libgnutls: Check the return code of getpwuid_r() instead of relying
1588 on the result value. That avoids issue in certain systems, when using
1589 tofu authentication and the home path cannot be determined. Issue reported
1592 ** libgnutls-dane: Improved dane_verify_session_crt(), which now attempts to
1593 create a full chain. This addresses points from https://savannah.gnu.org/support/index.php?108552
1595 ** gnutls-cli: --dane will only check the end certificate if PKIX validation
1598 ** gnutls-cli: --benchmark-soft-ciphers has been removed. That option cannot
1599 be emulated with the implicit initialization of gnutls.
1601 ** certtool: Allow multiple organizations and organizational unit names to
1602 be specified in a template.
1604 ** certtool: Warn when invalid configuration options are set to a template.
1606 ** ocsptool: Include path in ocsp request. This resolves #108582
1607 (https://savannah.gnu.org/support/?108582), reported by Matt McCutchen.
1609 ** API and ABI modifications:
1610 gnutls_credentials_get: Added
1613 * Version 3.3.2 (released 2014-05-06)
1615 ** libgnutls: Added the 'very weak' certificate verification profile
1616 that corresponds to 64-bit security level.
1618 ** libgnutls: Corrected file descriptor leak on random generator
1621 ** libgnutls: Corrected file descriptor leak on PSK password file
1622 reading. Issue identified using the Codenomicon TLS test suite.
1624 ** libgnutls: Avoid deinitialization if initialization has failed.
1626 ** libgnutls: null-terminate othername alternative names.
1628 ** libgnutls: gnutls_x509_trust_list_get_issuer() will operate correctly
1629 on a PKCS #11 trust list.
1631 ** libgnutls: Several small bug fixes identified using valgrind and
1632 the Codenomicon TLS test suite.
1634 ** libgnutls-dane: Accept a certificate using DANE if there is at least one
1635 entry that matches the certificate. Patch by simon [at] arlott.org.
1637 ** libgnutls-guile: Fixed compilation issue.
1639 ** certtool: Allow exporting a CRL on DER format.
1641 ** certtool: The ECDSA keys generated by default use the SECP256R1 curve
1642 which is supported more widely than the previously used SECP224R1.
1644 ** API and ABI modifications:
1645 GNUTLS_PROFILE_VERY_WEAK: Added
1648 * Version 3.3.1 (released 2014-04-19)
1650 ** libgnutls: Enforce more strict checks to heartbeat messages
1651 concerning padding and payload. Suggested by Peter Dettman.
1653 ** libgnutls: Allow decoding PKCS #8 files with ECC parameters
1656 ** libgnutls: Several small bug fixes found by coverity.
1658 ** libgnutls: The conditionally available self-test functions
1659 were moved to self-test.h.
1661 ** libgnutls: Fixed issue with the check of incoming data when two
1662 different recv and send pointers have been specified. Reported and
1663 investigated by JMRecio.
1665 ** libgnutls: Fixed issue in the RSA-PSK key exchange, which would
1666 result to illegal memory access if a server hint was provided. Reported
1669 ** libgnutls: Fixed client memory leak in the PSK key exchange, if a
1670 server hint was provided.
1672 ** libgnutls: Corrected the *get_*_othername_oid() functions.
1674 ** API and ABI modifications:
1675 No changes since last version.
1678 * Version 3.3.0 (released 2014-04-10)
1680 ** libgnutls: The initialization of the library was moved to a
1681 constructor. That is, gnutls_global_init() is no longer required
1682 unless linking with a static library or a system that does not
1683 support library constructors.
1685 ** libgnutls: static libraries are not built by default.
1687 ** libgnutls: PKCS #11 initialization is delayed to first usage.
1688 That avoids long delays in gnutls initialization due to broken PKCS #11
1691 ** libgnutls: The PKCS #11 subsystem is re-initialized "automatically"
1692 on the first PKCS #11 API call after a fork.
1694 ** libgnutls: certificate verification profiles were introduced
1695 that can be specified as flags to verification functions. They
1696 are enumerations in gnutls_certificate_verification_profiles_t
1697 and can be converted to flags for use in a verification function
1698 using GNUTLS_PROFILE_TO_VFLAGS().
1700 ** libgnutls: Added the ability to read system-specific initial
1701 keywords, if they are prefixed with '@'. That allows a compile-time
1702 specified configuration file to be used to read pre-configured priority
1703 strings from. That can be used to impose system specific policies.
1705 ** libgnutls: Increased the default security level of priority
1706 strings (NORMAL and PFS strings require at minimum a 1008 DH prime),
1707 and set a verification profile by default. The LEGACY keyword is
1708 introduced to set the old defaults.
1710 ** libgnutls: Added support for the name constraints PKIX extension.
1711 Currently only DNS names and e-mails are supported (no URIs, IPs
1714 ** libgnutls: Security parameter SEC_PARAM_NORMAL was renamed to
1715 SEC_PARAM_MEDIUM to avoid confusion with the priority string NORMAL.
1717 ** libgnutls: Added new API in x509-ext.h to handle X.509 extensions.
1718 This API handles the X.509 extensions in isolation, allowing to parse
1719 similarly formatted extensions stored in other structures.
1721 ** libgnutls: When generating DSA keys the macro GNUTLS_SUBGROUP_TO_BITS
1722 can be used to specify a particular subgroup as the number of bits in
1723 gnutls_privkey_generate; e.g., GNUTLS_SUBGROUP_TO_BITS(2048, 256).
1725 ** libgnutls: DH parameter generation is now delegated to nettle.
1726 That unfortunately has the side-effect that DH parameters longer than
1727 3072 bits, cannot be generated (not without a nettle update).
1729 ** libgnutls: Separated nonce RNG from the main RNG. The nonce
1730 random number generator is based on salsa20/12.
1732 ** libgnutls: The buffer alignment provided to crypto backend is
1733 enforced to be 16-byte aligned, when compiled with cryptodev
1734 support. That allows certain cryptodev drivers to operate more
1737 ** libgnutls: Return error when a public/private key pair that doesn't
1738 match is set into a credentials structure.
1740 ** libgnutls: Depend on p11-kit 0.20.0 or later.
1742 ** libgnutls: The new padding (%NEW_PADDING) experimental TLS extension has
1743 been removed. It was not approved by IETF.
1745 ** libgnutls: The experimental xssl library is removed from the gnutls
1748 ** libgnutls: Reduced the number of gnulib modules used in the main library.
1750 ** libgnutls: Added priority string %DISABLE_WILDCARDS.
1752 ** libgnutls: Added the more extensible verification function
1753 gnutls_certificate_verify_peers(), that allows checking, in addition
1754 to a peer's DNS hostname, for the key purpose of the end certificate
1755 (via PKIX extended key usage).
1757 ** certtool: Timestamps for serial numbers were increased to 8 bytes,
1758 and in batch mode to 12 (appended with 4 random bytes).
1760 ** certtool: When no CRL number is provided (or value set to -1), then
1761 a time-based number will be used, similarly to the serial generation
1762 number in certificates.
1764 ** certtool: Print the SHA256 fingerprint of a certificate in addition
1767 ** libgnutls: Added --enable-fips140-mode configuration option (unsupported).
1768 That option enables (when running on FIPS140-enabled system):
1769 o RSA, DSA and DH key generation as in FIPS-186-4 (using provable primes)
1770 o The DRBG-CTR-AES256 deterministic random generator from SP800-90A.
1771 o Self-tests on initialization on ciphers/MACs, public key algorithms
1772 and the random generator.
1773 o HMAC-SHA256 verification of the library on load.
1774 o MD5 is included for TLS purposes but cannot be used by the high level
1776 o All ciphers except AES are disabled.
1777 o All MACs and hashes except GCM and SHA are disabled (e.g., HMAC-MD5).
1778 o All keys (temporal and long term) are zeroized after use.
1779 o Security levels are adjusted to the FIPS140-2 recommendations (rather

2111 gnutls_handshake_set_random: Added
2112 gnutls_transport_set_int2: Added
2113 gnutls_transport_get_int2: Added
2114 gnutls_transport_get_int: Added
2115 gnutls_record_cork: Exported
2116 gnutls_record_uncork: Exported
2117 gnutls_pkcs11_privkey_status: Added
2120 * Version 3.1.8 (released 2013-02-10)
2122 ** libgnutls: Fixed issue in gnutls_x509_privkey_import2() which didn't return
2123 GNUTLS_E_DECRYPTION_FAILED in all cases, and affect certtool operation
2124 with encrypted keys. Reported by Yan Fiz.
2126 ** libgnutls: The minimum DH bits accepted by priorities NORMAL and
2127 PERFORMANCE was set to previous defaults 727 bits. Reported by Diego
2130 ** libgnutls: Corrected issue which prevented gnutls_pubkey_verify_hash()
2131 to operate with long keys. Reported by Erik A Jensen.
2133 ** API and ABI modifications:
2134 No changes since last version.
2137 * Version 3.1.7 (released 2013-02-04)
2139 ** certtool: Added option "dn" which allows to directly set the DN
2140 in a template from an RFC4514 string.
2142 ** danetool: Added options: --dlv and --insecure. Suggested by Paul Wouters.
2144 ** libgnutls-xssl: Added a new library to simplify GnuTLS usage.
2146 ** libgnutls-dane: Added function to specify a DLV file.
2148 ** libgnutls: Heartbeat code was made optional.
2150 ** libgnutls: Fixes in server side of DTLS-0.9.
2152 ** libgnutls: DN variable 'T' was expanded to 'title'.
2154 ** libgnutls: Fixes in record padding parsing to prevent a timing attack.
2155 Issue reported by Kenny Paterson and Nadhem Alfardan.
2157 ** libgnutls: Added functions to directly set the DN in a certificate
2158 or request from an RFC4514 string.
2160 ** libgnutls: Optimizations in the random generator. The re-seeding of
2161 it is now explicitly done on every session deinit.
2163 ** libgnutls: Simplified the DTLS sliding window implementation.
2165 ** libgnutls: The minimum DH bits accepted by a client are now set
2166 by the specified priority string. The current values correspond to the
2167 previous defaults (727 bits), except for the SECURE128 and SECURE192
2168 strings which increase the minimum to 1248 and 1776 respectively.
2170 ** libgnutls: Added the gnutls_record_cork() and uncork API to enable
2171 buffering in sending application data.
2173 ** libgnutls: Removed default random padding, and added a length-hiding interface
2174 instead. Both the server and the client must support this extension. Whether
2175 length-hiding can be used on a given session can be checked using
2176 gnutls_record_can_use_length_hiding(). Contributed by Alfredo Pironti.
2178 ** libgnutls: Added the experimental %NEW_PADDING priority string. It enables
2179 a new padding mechanism in TLS allowing arbitrary padding in TLS records
2180 in all ciphersuites, which makes length-hiding more efficient and solves
2181 the issues with timing attacks on CBC ciphersuites.
2183 ** libgnutls: Corrected gnutls_cipher_decrypt2() when used with AEAD
2184 ciphers (i.e., AES-GCM). Reported by William McGovern.

2226 ** libgnutls: Ignore heartbeat messages when received out-of-order,
2227 instead of issuing an error.
2229 ** libgnutls: Stricter RSA PKCS #1 1.5 encoding and decoding. Reported
2232 ** libgnutls: TPM support is disabled by default because GPL programs
2233 cannot link with it. Use --with-tpm to enable it.
2235 ** libgnutls-guile: Fixed parallel compilation issue.
2237 ** gnutls-cli: It will try to connect to all possible returned addresses
2240 ** API and ABI modifications:
2241 No changes since last version.
2244 * Version 3.1.5 (released 2012-11-24)
2246 ** libgnutls: Added functions to parse the certificates policies
2249 ** libgnutls: Handle BMPString (UCS-2) encoding in the Distinguished
2250 Name by translating it to UTF-8 (works on windows or systems with iconv).
2252 ** libgnutls: Added PKCS #11 key generation function that returns the
2253 public key on generation.
2255 ** libgnutls: Corrected bug in priority string parsing, that mostly
2256 affected combined levels. Patch by Tim Kosse.
2258 ** certtool: The --pubkey-info option can be combined with the
2259 --load-privkey or --load-request to print the corresponding public keys.
2261 ** certtool: It is able to set certificate policies via a template.
2263 ** certtool: Added --hex-numbers option which prints big numbers in
2264 an easier to parse format.
2266 ** p11tool: After key generation, outputs the public key (useful in
2267 tokens that do not store the public key).
2269 ** danetool: It is being built even without libgnutls-dane (the
2270 --check functionality is disabled though).
2272 ** API and ABI modifications:
2273 gnutls_pkcs11_privkey_generate2: Added
2274 gnutls_x509_crt_get_policy: Added

2284 ** libgnutls: gnutls_certificate_verify_peers2() will set flags depending on
2285 the available revocation data validity.
2287 ** libgnutls: Added gnutls_certificate_verification_status_print(),
2288 a function to print the verification status code in human readable text.

2304 ** libgnutls: Added verification flag GNUTLS_VERIFY_DO_NOT_ALLOW_UNSORTED_CHAIN
2305 and made GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN the default.
2307 ** libgnutls: Always tolerate key usage violation errors from the side
2308 of the peer, but also notify via an audit message.
2310 ** gnutls-cli: Added --local-dns option.
2312 ** danetool: Corrected bug that prevented loading PEM files.
2314 ** danetool: Added --check option to allow querying and verifying

2359 Reported by danblack at http://savannah.gnu.org/support/?108146
2361 ** libgnutls: Added functions to export structures in an allocated buffer.
2363 ** libgnutls: Added gnutls_ocsp_resp_check_crt() to check whether the OCSP
2364 response corresponds to the given certificate.
2366 ** libgnutls: In client side gnutls_init() enables the session ticket and
2367 OCSP certificate status request extensions by default. The flag
2368 GNUTLS_NO_EXTENSIONS can be used to prevent that.
2370 ** libgnutls: Several updates in the OpenPGP code. The generating code
2371 is fully RFC6091 compliant and RFC5081 support is only supported in client
2374 ** libgnutls-dane: Added. It is a library to provide DANE with DNSSEC
2375 certificate verification.
2377 ** gnutls-cli: Added --dane option to enable DANE certificate verification.
2379 ** danetool: Added tool to generate DANE TLSA Resource Records (RR).

2417 ** libgnutls: Fixed bug in gnutls_x509_trust_list_add_system_trust()
2418 and gnutls_x509_trust_list_add_trust_mem() that prevented the loading
2419 of certificates in the windows platform.
2421 ** libgnutls: Corrected bug in OpenPGP subpacket encoding.
2423 ** libgnutls: Added support for DTLS/TLS heartbeats by Olga Smolenchuk.
2424 (the work was done during Google Summer of Code).
2426 ** libgnutls: Added X.509 certificate verification flag
2427 GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN. This flag allows the verification
2428 of unsorted certificate chains and is enabled by default for
2429 TLS certificate verification (if gnutls_certificate_set_verify_flags()
2430 does not override it).
2432 ** libgnutls: Prints warning on certificates that contain keys of
2433 an insecure level. If the %COMPAT priority flag is not specified
2434 the TLS connection fails.
2436 ** libgnutls: Correctly restore gnutls_record_recv() in DTLS mode
2437 if interrupted during the retrasmition of handshake data.
2439 ** libgnutls: Better mingw32 support (patch by LRN).
2441 ** libgnutls: The %COMPAT keyword, if specified, will tolerate
2442 key usage violation errors (they are far too common to ignore).
2444 ** libgnutls: Added GNUTLS_STATELESS_COMPRESSION flag to gnutls_init(),
2445 which provides a tool to counter compression-related attacks where
2446 parts of the data are controlled by the attacker _and_ are placed in
2447 separate records (use with care - do not use compression if not sure).
2449 ** libgnutls: Depends on libtasn1 2.14 or later.
2451 ** certtool: Prints the number of bits of the public key algorithm
2452 parameter in a private key.
2454 ** API and ABI modifications:
2455 gnutls_x509_privkey_get_pk_algorithm2: Added
2456 gnutls_heartbeat_ping: Added
2457 gnutls_heartbeat_pong: Added
2458 gnutls_heartbeat_allowed: Added

2461 gnutls_heartbeat_get_timeout: Added
2462 GNUTLS_SEC_PARAM_WEAK: Added
2463 GNUTLS_SEC_PARAM_INSECURE: Added
2465 * Version 3.1.1 (released 2012-09-02)
2467 ** gnutls-serv: Listens on IPv6. Patch by Bernhard R. Link.
2469 ** certtool: Changes in password handling of certtool.
2470 Ask password when required and only if the '--password' option is not
2471 given. If the '--password' option is given during key generation then
2472 assume the PKCS #8 file format, instead of ignoring the password.
2474 ** tpmtool: No longer asks for key password in registered keys.
2476 ** libgnutls: Elliptic curve code was optimized by Ilya Tumaykin.
2477 wmNAF is now used for point multiplication and other optimizations.
2478 (the major part of the work was done during Google Summer of Code).
2480 ** libgnutls: The default pull_timeout_function only uses select
2481 instead of a combination of select() and recv() to prevent issues
2482 when used in stream sockets in some systems.
2484 ** libgnutls: Be tolerant in ECDSA signature violations (e.g. using
2485 SHA256 with a SECP384 curve instead of SHA-384), to interoperate with
2488 ** libgnutls: Fixed DSA and ECDSA signature generation in smart
2489 cards. Thanks to Andreas Schwier from cardcontact.de for providing
2490 me with ECDSA capable smart cards.
2492 ** API and ABI modifications:
2493 gnutls_sign_algorithm_get: Added
2494 gnutls_sign_get_hash_algorithm: Added
2495 gnutls_sign_get_pk_algorithm: Added
2498 * Version 3.1.0 (released 2012-08-15)
2500 ** libgnutls: Added direct support for TPM as a cryptographic module
2501 in gnutls/tpm.h. TPM keys can be used in functions accepting files
2502 using URLs of the following types:
2503 tpmkey:file=/path/to/file
2504 tpmkey:uuid=7f468c16-cb7f-11e1-824d-b3a4f4b20343;storage=user
2506 ** libgnutls: Priority string level keywords can be combined.
2507 For example the string "SECURE256:+SUITEB128" is now allowed.
2509 ** libgnutls: requires libnettle 2.5.
2511 ** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
2512 for encryption and signatures.
2514 ** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
2515 generic errors and signature verification errors in the verification
2518 ** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
2519 to simplify parsing in most PKCS #12 use cases.
2521 ** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
2522 the whole certificate chain (if any) to the credentials structure, instead
2523 of only the end-user certificate.
2525 ** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
2526 and gnutls_x509_privkey_import_pkcs8(), return consistently
2527 GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
2528 password was provided.
2530 ** libgnutls: Added gnutls_handshake_set_timeout() a function that
2531 allows to set the maximum time spent in a handshake.
2533 ** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
2536 ** tpmtool: Added. It is a tool to generate private keys in the
2539 ** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
2540 and --benchmark-tls-ciphers
2542 ** certtool: generated PKCS #12 structures may hold more than one
2543 private key. Patch by Lucas Fisher.
2545 ** certtool: Added option --null-password to generate/decrypt keys
2546 that use a NULL password (in schemas that distinguish between NULL
2547 an empty passwords).
2549 ** minitasn1: Upgraded to libtasn1 version 2.13.

2674 ** libgnutls: When decoding a PKCS #11 URL the pin-source field
2675 is assumed to be a file that stores the pin. Based on patch
2678 ** libgnutls: gnutls_record_check_pending() no longer
2679 returns unprocessed data, and thus ensure the non-blocking
2680 of the next call to gnutls_record_recv().

2829 for the RFC6460 requirements.
2831 ** libgnutls: Added new security parameter GNUTLS_SEC_PARAM_LEGACY
2832 to account for security level of 96-bits.
2834 ** libgnutls: In client side if server does not advertise any

2838 ** libgnutls: Added functions to parse authority key identifiers
2839 when stored as a 'general name' and serial combo.
2841 ** libgnutls: Added function to force explicit reinitialization

2873 is to parse and extract information from OCSP requests/responses, to
2874 generate OCSP requests and to verify OCSP responses. See the manual
2875 for more information. Run ./configure with --disable-ocsp to build
2876 GnuTLS without OCSP support.
2878 This work was sponsored by Smoothwall <http://smoothwall.net/>.
2880 ** ocsptool: Added new command line tool.
2881 The tool can parse OCSP request/responses, generate OCSP requests and

2958 ** gnutls-cli: Fixed reading from windows terminals.
2960 ** libgnutls: When GNUTLS_OPENPGP_FMT_BASE64 is specified
2961 the stream is assumed to be base64 encoded (previously
2962 the encoding was auto-detected). This avoids a decoding
2963 issue in windows systems.

2985 it will only list the ciphersuites that are enabled by the given
2988 ** libgnutls: Added new priority string %SERVER_PRECEDENCE, which
2989 changes the ciphersuite selection procedure. If specified the server
2990 priorities will be used for selection instead of the client's.
2992 ** libgnutls: Optimizations in Diffie-Hellman parameters generation
2995 ** libgnutls: When session tickets are negotiated and used in a
2996 session, a server will not store that session data into its cache.

3000 ** libgnutls: Added gnutls_priority_get_cipher_suite_index() to
3001 allow listing the ciphersuites enabled in a priority structure.
3002 It outputs an index to be used in gnutls_get_cipher_suite_info().
3004 ** libgnutls: Optimizations in the elliptic curve code --timing
3005 attacks resistant code is only used in ECDSA private key operations.

3028 The reason was that the code that auto-generated the man pages missed
3029 many APIs and we couldn't fix it (volunteers welcome). See the info
3030 manual or the GTK-DOC manual instead.
3032 ** API and ABI modifications:
3033 gnutls_x509_privkey_verify_params: Added

3667 ** libgnutls: Record version of Client Hellos is now set by default to
3668 SSL 3.0. To restore the previous default behavior use %LATEST_RECORD_VERSION
3671 ** libgnutls: Use ASN1_NULL when writing parameters for RSA signatures.
3672 This makes us comply with RFC3279. Reported by Michael Rommel.
3674 ** gnutls-serv: Corrected a buffer overflow. Reported and patch by Tomas Mraz.
3676 ** API and ABI modifications:
3677 No changes since last version.
3679 * Version 2.11.5 (released 2010-12-01)
3681 ** libgnutls: Reverted default behavior for verification and
3682 introduced GNUTLS_VERIFY_DO_NOT_ALLOW_X509_V1_CA_CRT. Thus by default
3683 V1 trusted CAs are allowed, unless the new flag is specified.
3685 ** libgnutls: Correctly add leading zero to PKCS #8 encoded DSA key.
3686 Reported by Jeffrey Walton.
3688 ** libgnutls: Added SIGN-ALL, CTYPE-ALL, COMP-ALL, and VERS-TLS-ALL
3689 as priority strings. Those allow to set all the supported algorithms
3692 ** p11tool: Introduced. It allows manipulating pkcs 11 tokens.
3694 ** gnutls-cli: Print channel binding only in verbose mode.
3695 Before it printed it after the 'Compression:' output, thus breaking
3696 Emacs starttls.el string searches.
3698 ** API and ABI modifications:
3699 gnutls_pkcs11_token_init: New function
3700 gnutls_pkcs11_token_set_pin: New function
3702 * Version 2.11.4 (released 2010-10-15)
3704 ** libgnutls: Add new API gnutls_session_channel_binding.
3705 The function is used to get the channel binding data. Currently only
3706 the "tls-unique" (RFC 5929) channel binding type is supported, through
3707 the GNUTLS_CB_TLS_UNIQUE type. See new section "Channel Bindings" in
3710 ** gnutls-cli, gnutls-serv: Print 'tls-unique' Channel Bindings.
3712 ** doc: Added pkcs11.h header file to GTK-DOC manual.
3714 ** build: Update gnulib files.
3716 ** i18n: Update translations.
3718 ** tests: Add self tests gendh.c. Speed up Guile self checks.
3720 ** API and ABI modifications:
3721 gnutls_session_channel_binding: New function.
3722 gnutls_channel_binding_t: New enumeration.
3723 GNUTLS_CB_TLS_UNIQUE: New gnutls_channel_binding_t enum member.
3724 GNUTLS_E_CHANNEL_BINDING_NOT_AVAILABLE: New error code.
3726 * Version 2.11.3 (released 2010-10-14)
3728 ** Indent code to follow the GNU Coding Standard.
3729 You should be able to unpack the 2.11.2 release and run 'make indent'
3730 twice to get exactly the same content as 2.11.3 except for generated
3731 files. Using GNU Indent 2.2.11.
3733 ** API and ABI modifications:
3734 No changes since last version.
3736 * Version 2.11.2 (released 2010-10-08)
3738 ** libgnutls: Several bug fixes on session resumption
3739 and session tickets support.
3741 ** libgnutls: Add new extended key usage ipsecIKE.
3743 ** certtool: Renamed PKCS #11 options to: --p11-provider,
3744 --p11-export-url, --p11-list-certs, --p11-list-certs,
3745 --p11-list-privkeys, --p11-list-trusted, --p11-list-all-certs,
3746 --p11-list-all, --p11-list-tokens, --p11-login, --p11-write,
3747 --p11-write-label, --p11-write-trusted, --p11-detailed-url,
3750 ** libgnutls: Corrected bug that caused importing DSA keys as RSA,
3751 introduced with the new nettle code.
3753 ** libgnutls: Corrected advertizing issue for session tickets.
3755 ** API and ABI modifications:
3756 gnutls_x509_crt_get_subject_unique_id: ADDED.
3757 gnutls_x509_crt_get_issuer_unique_id: ADDED.
3759 * Version 2.11.1 (released 2010-09-14)
3761 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
3762 to use the libgcrypt back end.
3764 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
3765 backend crypto library.
3767 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
3769 ** libgnutls: Several updates in the buffering internal interface.
3771 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
3772 tabs are being skipped.
3774 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
3776 ** libgnutls: The %COMPAT flag now allows larger records that violate the
3779 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
3780 system calls. Applications that depended on it being 1 should explicitly call
3781 gnutls_transport_set_lowat().
3783 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
3784 to ECRYPT II recommendations. Mappings were moved to a single location
3785 and DSA keys are handled differently (since DSA2 allows for 1024,2048
3786 and 3072 keys only).
3788 ** libgnutls: gnutls_x509_privkey_import() will fallback to
3789 gnutls_x509_privkey_import_pkcs8() without a password, if it
3790 is unable to decode the key.
3792 ** libgnutls: HMAC-MD5 no longer used by default.
3794 ** API and ABI modifications:
3795 gnutls_openpgp_privkey_sec_param: ADDED
3796 gnutls_x509_privkey_sec_param: ADDED
3798 * Version 2.11.0 (released 2010-07-22)
3800 ** libgnutls: support scattered write using writev(). This takes
3801 advantage of the new buffering layer and allows queuing of packets
3802 and flushing them. This is currently used for handshake messages
3805 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
3806 alternative locking procedures. By default the system available
3807 locking is used. In *NIX pthreads are used and in windows the
3808 critical section API. This follows a different approach than the
3809 previous versions that depended on libgcrypt initialization. The
3810 locks are now set by default in systems that support it. Programs
3811 that used gcry_control() to set thread locks should insert it into
3813 #if GNUTLS_VERSION_NUMBER <= 0x020b00
3817 ** libgnutls: Added support for reading DN from EV-certificates.
3819 jurisdictionOfIncorporationLocalityName,
3820 jurisdictionOfIncorporationStateOrProvinceName,
3821 jurisdictionOfIncorporationCountryName
3823 ** libgnutls: Added support for DSA signing/verifying with bit
3826 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
3827 has to be called to register any required md5 handlers.
3829 ** libgnutls: Internal buffering code was replaced by simpler
3830 code contributed by Jonathan Bastien-Filiatrault.
3832 ** libgnutls: Internal API for extensions augmented to allow
3833 safe storing and loading of data on resumption. This allows writing
3834 self-contained extensions (when possible). As a side effect
3835 the OPRFI extension was removed.
3837 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
3839 ** libgnutls: Added PKCS #11 support and an API to access objects in
3840 gnutls/pkcs11.h. Currently certificates and public keys can be
3841 imported from tokens, and operations can be performed on private keys.
3843 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
3845 ** libgnutls: Added initial support for the nettle library. It uses
3846 the system's random generator for seeding. That is /dev/urandom in Linux,
3847 system calls in Win32 and EGD on other systems.
3849 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
3850 works even when resuming a session.
3852 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
3853 similar gnutls_certificate_set_server_retrieve_function() and
3854 gnutls_certificate_set_client_retrieve_function(). In addition it support
3855 PKCS #11 private keys.
3857 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
3858 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
3860 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
3861 sizes for private keys using a human understandable scale.
3863 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
3864 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
3865 --pkcs11-delete-url, --pkcs11-write
3867 certtool: The --pkcs-cipher is taken into account when generating a
3868 private key. The default cipher used now is aes-128. The old behavior can
3869 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
3871 certtool: Added --certificate-pubkey to print the public key of the
3874 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
3875 can now accept a PKCS #11 URL in addition to a file. This will allow for
3876 example to use the Gnome-keyring trusted certificate list to verify
3877 connections using a url such as:
3878 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

3959 * Version 2.10.1 (released 2010-07-25)
3961 ** libgnutls: Added support for broken certificates that indicate RSA
3964 ** gnutls-cli: Allow verification using V1 CAs.
3966 ** libgnutls: gnutls_x509_privkey_import() will fallback to
3967 gnutls_x509_privkey_import_pkcs8() without a password, if it
3968 is unable to decode the key.
3970 ** libgnutls: Correctly deinitialize crypto API functions to prevent
3971 a memory leak. Reported by Mads Kiilerich.
3973 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
3974 issue a warning, that the output key might not be working everywhere.
3976 ** certtool: The --pkcs-cipher is taken into account when generating a
3977 private key. The default cipher used now is aes-128. The old behavior
3978 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
3980 ** API and ABI modifications:
3981 No changes since last version.
3983 * Version 2.10.0 (released 2010-06-25)
3985 ** API and ABI modifications:
3986 No changes since last version.
3988 * Version 2.9.12 (released 2010-06-17)
3990 ** gnutls-cli: Make --starttls work again.
3991 Problem introduced in patch to use read() instead of fgets() committed
3994 ** API and ABI modifications:
3995 No changes since last version.
3997 * Version 2.9.11 (released 2010-06-07)
3999 ** libgnutls: Removed two APIs related to safe renegotiation.
4000 Use priority strings instead. The APIs were
4001 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
4002 (Remember that we don't promise ABI stability during development
4003 series, so this doesn't cause an shared library ABI increment.)
4005 ** tests: More self testing of safe renegotiation extension.
4006 See tests/safe-renegotiation/README for more information.
4008 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
4010 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
4012 ** API and ABI modifications:
4013 gnutls_safe_negotiation_set_initial: REMOVED.
4014 gnutls_safe_renegotiation_set: REMOVED.
4016 * Version 2.9.10 (released 2010-04-22)
4018 ** libgnutls: Time verification extended to trusted certificate list.
4019 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
4022 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
4023 Based on patch by Pavan Konjarla. Adds new constant
4024 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
4026 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
4027 Solves the issue discussed in:
4028 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
4029 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
4030 Note that to allow connecting to unpatched servers the full protection
4031 is only enabled if the priority string %SAFE_RENEGOTIATION is
4032 specified. You can check whether protection is in place by querying
4033 gnutls_safe_renegotiation_status(). New error codes
4034 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
4035 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
4037 ** libgnutls: When checking openpgp self signature also check the signatures
4039 Ilari Liusvaara noticed and reported the issue and provided test
4042 ** libgnutls: Added cryptodev support (/dev/crypto).
4043 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
4044 benchmark utility for AES. Adds new error codes
4045 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
4047 ** libgnutls: Exported API to access encryption and hash algorithms.
4048 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
4049 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
4050 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
4051 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
4052 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
4053 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
4054 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
4056 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
4057 verification of certificate upon receipt rather than waiting until the
4058 end of the handshake.
4060 ** libgnutls: Don't send alerts during handshake.
4061 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
4063 ** certtool: Corrected two issues that affected certificate request generation.
4064 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
4065 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
4066 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
4067 those parameters there since other implementations don't do either and having
4068 them does not seem to offer anything (anyway you need the signer's certificate
4069 to verify thus public key will be available). Found thanks to Boyan Kasarov.
4070 This however has the side-effect that public key IDs shown by certtool are
4071 now different than previous gnutls releases.
4072 (3) the option --pgp-certificate-info will verify self signatures
4074 ** certtool: Allow exporting of Certificate requests on DER format.
4076 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
4078 ** gnutls-cli: Handle reading binary data from server.
4079 Reported by and tiny patch from Vitaly Mayatskikh
4080 <v.mayatskih@gmail.com> in
4081 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/4096>.
4083 ** minitasn1: Upgraded to libtasn1 version 2.6.
4085 ** i18n: Updated Czech, Dutch, French, Polish, Swedish translation.

4140 ** API and ABI modifications:
4141 No changes since last version.
4143 * Version 2.9.8 (released 2009-11-05)
4145 ** libgnutls: Fix for memory leaks on interrupted handshake.
4146 Reported by Tang Tong.
4148 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
4149 ** extension and certificate verify field.
4150 This requires changes for TLS 1.2 servers and clients that use
4151 callbacks for certificate retrieval. They are now required to check

4239 Reported by Howard Chu <hyc@symas.com> in
4240 <https://savannah.gnu.org/support/?106975>.
4242 ** Fix use of deprecated types internally.
4243 Use of deprecated types in GnuTLS from now on will lead to a compile
4244 error, to prevent this from happening again.
4246 ** API and ABI modifications:
4247 No changes since last version.
4249 * Version 2.9.3 (released 2009-08-19)
4251 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
4252 The new APIs are gnutls_session_ticket_enable_client,
4253 gnutls_session_ticket_enable_server, and
4254 gnutls_session_ticket_key_generate.
4256 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.

4263 * Version 2.9.2 (released 2009-08-14)
4265 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
4266 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
4267 into 1) not printing the entire CN/SAN field value when printing a
4268 certificate and 2) cause incorrect positive matches when matching a
4269 hostname against a certificate. Some CAs apparently have poor
4270 checking of CN/SAN values and issue these (arguable invalid)
4271 certificates. Combined, this can be used by attackers to become a
4272 MITM on server-authenticated TLS sessions. The problem is mitigated
4273 since attackers needs to get one certificate per site they want to
4274 attack, and the attacker reveals his tracks by applying for a
4275 certificate at the CA. It does not apply to client authenticated TLS
4276 sessions. Research presented independently by Dan Kaminsky and Moxie
4277 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
4278 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
4280 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
4281 The function may fail incorrectly when an earlier certificate was
4282 imported to the same gnutls_x509_crt_t structure.
4284 ** minitasn1: Internal copy updated to libtasn1 v2.3.
4286 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
4287 Before it always returned false. Reported by Peter Hendrickson
4288 <pdh@wiredyne.com> in
4289 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3668>.
4291 ** libgnutls: Fix off-by-one size computation error in unknown DN printing.
4292 The error resulted in truncated strings when printing unknown OIDs in
4293 X.509 certificate DNs. Reported by Tim Kosse
4294 <tim.kosse@filezilla-project.org> in
4295 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3651>.
4297 ** libgnutls: Fix PKCS#12 decryption from password.
4298 The encryption key derived from the password was incorrect for (on
4299 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
4300 Tomas" <tomas.kukosa@siemens-enterprise.com> in
4301 <http://permalink.gmane.org/gmane.network.gnutls.general/1663>.

4304 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
4305 gnutls_dh_get_peers_public_bits. Before the reported value was
4306 overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in
4307 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.
4309 ** libgnutls: Avoid internal error when invoked after GNUTLS_E_AGAIN.

4313 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3670>.
4315 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
4316 Before we required that the runtime library used the same (or more
4317 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
4318 that the runtime usage is above the minimum required. Reported by
4319 Marco d'Itri <md@linux.it> via Andreas Metzler
4320 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.

4357 ** libgnutls: For CSRs, don't null pad integers for RSA/DSA value.
4358 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
4359 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
4361 Note: As a side effect of this change, the "public key identifier"
4362 value computed for a certificate using this version of GnuTLS will be
4363 different from values computed using earlier versions of GnuTLS.
4365 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
4366 ** optional SignatureAlgorithm parameter field.
4367 VeriSign rejected these CSRs. They are stricly speaking not needed
4368 since you need the signer's certificate to verify the certificate
4369 signature anyway. Reported by Wilankar Trupti
4370 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.

4629 No offically supported interfaces have been modified or removed. The
4630 library should be completely backwards compatible on both the source
4633 The shared library no longer exports some symbols that have never been
4634 officially supported, i.e., not mentioned in any of the header files.
4640 Normally when symbols are removed, the shared library version has to
4641 be incremented. This leads to a significant cost for everyone using
4642 the library. Because none of the above symbols have ever been
4643 intended for use by well-behaved applications, we decided that the it
4644 would be better for those applications to pay the price rather than
4645 incurring problems on the majority of applications.
4647 If it turns out that applications have been using unofficial
4648 interfaces, we will need to release a follow-on release on the v2.8
4649 branch to exports additional interfaces. However, initial testing
4650 suggests that few if any applications have been using any of the
4653 Although not a new change compared to 2.6.x, we'd like to remind you
4654 interfaces have been modified so that X.509 chain verification now
4655 also checks activation/expiration times on certificates. The affected

4826 ** libgnutls: Fix DSA key generation.
4827 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
4829 ** libgnutls: Check expiration/activation time on untrusted certificates.
4830 Merged from stable branch. Reported by Romain Francoise
4831 <romain@orebokech.com>. This changes the semantics of
4832 gnutls_x509_crt_list_verify, which in turn is used by
4833 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
4834 We add two new gnutls_certificate_status_t codes for reporting the new
4835 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
4836 We also add a new gnutls_certificate_verify_flags flag,
4837 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
4838 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
4840 ** lib: Linker version scripts reduces number of exported symbols.
4841 The linker version script now lists all exported ABIs explicitly, to
4842 avoid accidentally exporting unintended functions. Compared to
4843 before, most symbols beginning with _gnutls* are no longer exported.
4844 These functions have never been intended for use by applications, and
4845 there were no prototypes for these function in the public header
4846 files. Thus we believe it is possible to do this without incrementing
4847 the library ABI version which normally has to be done when removing an
4850 ** lib: Limit exported symbols on systems without LD linker scripts.
4851 Before all symbols were exported. Now we limit the exported symbols
4852 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
4853 _gnutls*. This is a superset of the actual supported ABI, but still
4854 an improvement compared to before. This is implemented using Libtool
4855 -export-symbols-regex. It is more portable than linker version
4858 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
4859 This should have been done in the last release.
4861 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
4862 Reported by Peter Hendrickson <pdh@wiredyne.com> in
4863 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
4865 ** doc: Improved sections for the info manual.
4866 We now follow the advice given by the texinfo manual on which
4867 directory categories to use. In particular, libgnutls moved from the
4868 'GNU Libraries' section to the 'Software libraries' and the command
4869 line tools moved from 'Network Applications' to 'System

4882 ** libgnutls: Applied patch by Cedric Bail to add functions
4883 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().

4896 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
4897 It is currently only used by the core library. This will enable a new
4898 domain 'gnutls' for translations of the command line tools.
4900 ** Corrected possible memory corruption on signature verification failure.
4901 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
4903 ** API and ABI modifications:
4904 gnutls_x509_crt_verify_hash: ADDED
4905 gnutls_x509_crt_get_verify_algorithm: ADDED
4907 * Version 2.7.6 (released 2009-02-27)
4909 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
4910 This applies both to generating certificates and certificate requests.
4912 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
4914 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
4915 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
4916 be used for chain verification.
4918 ** gnutls-serv: No longer disable MAC padding by default.
4919 Use --priority NORMAL:%COMPAT to disable MAC padding again.
4921 ** gnutls-cli: Certificate information output format changed.
4922 The tool now uses libgnutls' functions to print certificate
4923 information. This avoids code duplication.
4925 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
4926 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
4927 They can be used to override the default certificate chain validation
4930 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
4931 specify the client hello message record version. Used to overcome buggy
4932 TLS servers. Report by Martin von Gagern.
4934 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
4936 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
4938 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
4940 ** API and ABI modifications:
4941 No changes since last version.
4943 * Version 2.7.5 (released 2009-02-06)
4945 ** libgnutls: Accept chains where intermediary certs are trusted.
4946 Before GnuTLS needed to validate the entire chain back to a
4947 self-signed certificate. GnuTLS will now stop looking when it has
4948 found an intermediary trusted certificate. The new behaviour is
4949 useful when chains, for example, contains a top-level CA, an
4950 intermediary CA signed using RSA-MD5, and an end-entity certificate.
4951 To avoid chain validation errors due to the RSA-MD5 cert, you can
4952 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
4953 The signature on trusted certificates are not checked, so the chain
4954 has a chance to validate correctly. Reported by "Douglas E. Engert"
4955 <deengert@anl.gov> in
4956 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
4958 ** libgnutls: result_size in gnutls_hex_encode now holds
4959 the size of the result. Report by John Brooks <special@dereferenced.net>.
4961 ** libgnutls: gnutls_handshake when sending client hello during a
4962 rehandshake, will not offer a version number larger than the current.
4963 Reported by Tristan Hill <stan@saticed.me.uk>.
4965 ** libgnutls: Permit V1 Certificate Authorities properly.
4966 Before they were mistakenly rejected even though
4967 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
4968 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
4969 "Douglas E. Engert" <deengert@anl.gov> in
4970 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
4972 ** API and ABI modifications:
4973 No changes since last version.
4975 * Version 2.7.4 (released 2009-01-07)
4977 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
4978 This is a bugfix -- the previous attempt to do this from internal x509
4979 certificate verification procedures did not return the correct value
4980 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
4981 <dkg@fifthhorseman.net> in
4982 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
4983 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
4984 Gillmor <dkg@fifthhorseman.net>.
4986 ** libgnutls: New interface to get key id for certificate requests.
4987 Patch from David MarÃn Carreño <davefx@gmail.com> in
4988 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
4990 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
4992 ** certtool: --verify-chain now prints results of using library verification.
4993 Earlier, certtool --verify-chain used its own validation algorithm
4994 which wasn't guaranteed to give the same result as the libgnutls
4995 internal validation algorithm. Now this command print a new final
4996 line with header 'Chain verification output:' that contains the result
4997 from using the internal verification algorithm on the same chain.
4999 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
5001 ** API and ABI modifications:
5002 gnutls_x509_crq_get_key_id: ADDED.
5004 * Version 2.7.3 (released 2008-12-10)
5006 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
5007 Reported by Michael Kiefer <Michael-Kiefer@web.de> in
5008 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507633> forwarded by
5009 Andreas Metzler <ametzler@downhill.at.eu.org> in
5010 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
5012 ** libgnutls: Libgcrypt initialization changed.
5013 If libgcrypt has not already been initialized, GnuTLS will now
5014 initialize libgcrypt with disabled secure memory. Initialize
5015 libgcrypt explicitly in your application if you want to enable secure
5016 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
5017 allocation functions, which doesn't use secure memory, so there is no
5018 real change in behaviour.
5020 ** libgnutls: Fix memory leak in PSK authentication.
5021 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
5022 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
5024 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
5026 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
5027 It needs to be invoked before libgcrypt is initialized.
5029 ** gnutls-cli: Return non-zero exit code on error conditions.
5031 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
5033 ** tests: Added chainverify self-test that tests X.509 chain verifications.
5035 ** API and ABI modifications:
5036 No changes since last version.
5038 * Version 2.7.2 (released 2008-11-18)
5040 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
5041 The flaw makes it possible for man in the middle attackers (i.e.,
5042 active attackers) to assume any name and trick GnuTLS clients into
5043 trusting that name. Thanks for report and analysis from Martin von
5044 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
5046 Any updates with more details about this vulnerability will be added
5047 to <https://www.gnu.org/software/gnutls/security.html>
5049 ** libgnutls: Fix namespace issue with version symbols.
5050 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
5051 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
5052 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
5053 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
5054 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
5055 work but are deprecated.
5057 ** certtool: allow setting arbitrary key purpose object identifiers.
5059 ** libgnutls: Fix detection of C99 macros, to make debug logging work again.
5061 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
5062 Reported by Kevin Quick <quick@sparq.org> in
5063 <https://savannah.gnu.org/support/index.php?106454>.

5070 ** libgnutls: Change detection of when to use a linker version script.
5071 Use --enable-ld-version-script or --disable-ld-version-script to
5072 override auto-detection logic.

5140 ** tests: Make tests compile when using internal libtasn1.
5141 Patch by ludo@gnu.org (Ludovic Courtès).
5143 ** Changed detection of libtasn1 and libgcrypt to avoid depending on *-config.
5144 We now require a libgcrypt that has Camellia constants declared in
5145 gcrypt.h, which means v1.3.0 or later.

5173 * Version 2.6.6 (released 2009-04-30)
5175 ** libgnutls: Corrected double free on signature verification failure.
5176 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
5177 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
5179 ** libgnutls: Fix DSA key generation.
5180 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
5181 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
5182 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
5184 ** libgnutls: Check expiration/activation time on untrusted certificates.
5185 Reported by Romain Francoise <romain@orebokech.com>. Before the
5186 library did not check activation/expiration times on certificates, and
5187 was documented as not doing so. We have realized that many
5188 applications that use libgnutls, including gnutls-cli, fail to perform
5189 proper checks. Implementing similar logic in all applications leads
5190 to code duplication. Hence, we decided to check whether the current
5191 time (as reported by the time function) is within the
5192 activation/expiration period of certificates when verifying untrusted
5195 This changes the semantics of gnutls_x509_crt_list_verify, which in
5196 turn is used by gnutls_certificate_verify_peers and
5197 gnutls_certificate_verify_peers2. We add two new
5198 gnutls_certificate_status_t codes for reporting the new error
5199 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
5200 add a new gnutls_certificate_verify_flags flag,
5201 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
5204 More details about the vulnerabilities will be posted at
5205 <https://www.gnu.org/software/gnutls/security.html>.
5207 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
5208 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
5209 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
5211 ** tests: Fix linking of tests/openpgp/keyring self-test.
5212 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
5214 ** API and ABI modifications:
5215 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
5216 gnutls_certificate_verify_peers: Likewise.
5217 gnutls_certificate_verify_peers2: Likewise.
5218 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
5219 GNUTLS_CERT_EXPIRED: ADDED.
5220 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
5222 * Version 2.6.5 (released 2009-04-11)
5224 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
5225 specify the client hello message record version. Used to overcome buggy
5226 TLS servers. Report by Martin von Gagern.
5228 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
5229 Libtasn1 0.3.4 or later is required. This is to align with the
5230 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
5232 ** API and ABI modifications:
5233 No changes since last version.
5235 * Version 2.6.4 (released 2009-02-06)
5237 ** libgnutls: Accept chains where intermediary certs are trusted.
5238 Before GnuTLS needed to validate the entire chain back to a
5239 self-signed certificate. GnuTLS will now stop looking when it has
5240 found an intermediary trusted certificate. The new behaviour is
5241 useful when chains, for example, contains a top-level CA, an
5242 intermediary CA signed using RSA-MD5, and an end-entity certificate.
5243 To avoid chain validation errors due to the RSA-MD5 cert, you can
5244 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
5245 The signature on trusted certificates are not checked, so the chain
5246 has a chance to validate correctly. Reported by "Douglas E. Engert"
5247 <deengert@anl.gov> in
5248 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
5250 ** libgnutls: result_size in gnutls_hex_encode now holds
5251 the size of the result. Report by John Brooks <special@dereferenced.net>.
5253 ** libgnutls: gnutls_handshake when sending client hello during a
5254 rehandshake, will not offer a version number larger than the current.
5255 Reported by Tristan Hill <stan@saticed.me.uk>.
5257 ** libgnutls: Permit V1 Certificate Authorities properly.
5258 Before they were mistakenly rejected even though
5259 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
5260 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
5261 "Douglas E. Engert" <deengert@anl.gov> in
5262 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
5264 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
5265 This is a bugfix -- the previous attempt to do this from internal x509
5266 certificate verification procedures did not return the correct value
5267 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
5268 <dkg@fifthhorseman.net> in
5269 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
5270 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
5271 Gillmor <dkg@fifthhorseman.net>.

5289 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
5290 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
5292 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
5293 It needs to be invoked before libgcrypt is initialized.
5295 ** gnutls-cli: Return non-zero exit code on error conditions.
5297 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
5299 ** API and ABI modifications:
5300 No changes since last version.
5302 * Version 2.6.2 (released 2008-11-12)
5304 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
5305 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
5306 problem for certificate chains that contained just one self-signed
5307 certificate. Reported by Michael Meskes <meskes@debian.org> in
5308 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505279>.
5310 ** API and ABI modifications:
5311 No changes since last version.
5313 * Version 2.6.1 (released 2008-11-10)
5315 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
5316 The flaw makes it possible for man in the middle attackers (i.e.,
5317 active attackers) to assume any name and trick GnuTLS clients into
5318 trusting that name. Thanks for report and analysis from Martin von
5319 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
5321 Any updates with more details about this vulnerability will be added
5322 to <https://www.gnu.org/software/gnutls/security.html>
5324 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
5325 Reported by Kevin Quick <quick@sparq.org> in
5326 <https://savannah.gnu.org/support/index.php?106454>.
5328 ** libgnutls-extra: Protect internal symbols with static.
5329 Fixes problem when linking certtool statically. Tiny patch from Aaron
5330 Ucko <ucko@ncbi.nlm.nih.gov>.
5332 ** libgnutls-openssl: Fix patch against X509_get_issuer_name.
5333 It incorrectly returned the subject DN instead of issuer DN in v2.6.0.
5334 Thanks to Thomas Viehmann <tv@beamnet.de> for report.
5336 ** certtool: Print a PKCS #8 key even if it is not encrypted.
5338 ** tests: Make tests compile when using internal libtasn1.
5339 Patch by ludo@gnu.org (Ludovic Courtès).
5341 ** API and ABI modifications:
5342 No changes since last version.
5344 * Version 2.6.0 (released 2008-10-06)
5346 ** libgnutls: Correct printing and parsing of IPv6 addresses.
5348 ** libgnutls-openssl: fix out of bounds access.
5349 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
5350 from Thomas Viehmann <tv@beamnet.de>.
5352 ** certtool: Use inet_pton for parsing IPv6 addresses.
5354 ** Major changes compared to the v2.4 branch:
5356 *** Added API to replace and update the crypto backend.
5358 *** certtool: can add several subject alternative names via template file.
5360 *** opencdk: Parse (but not decrypt) encrypted secret keys.
5362 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
5363 either set or append alternative names. It can also handle binary structures
5364 such as IP addresses.
5366 *** libgnutls: New function to set minimum acceptable SRP bits.
5367 The function is gnutls_srp_set_prime_bits.
5369 *** libgnutls: Add interface to deal with public key and signature algorithms.
5370 The functions are called gnutls_pk_list, gnutls_pk_get_id,
5371 gnutls_sign_list, and gnutls_sign_get_id.
5373 *** libgnutls: New interfaces to get name of public key and signing algorithms.
5374 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
5376 *** libgnutls: New API to get a string corresponding to a error symbol.
5377 The function is gnutls_strerror_name.
5379 *** libgnutls: New API to set the public parameters in a certificate request
5380 *** from a private key.
5381 The function is gnutls_x509_crq_set_key_rsa_raw.
5383 *** libgnutls: New API to set a callback to extract TLS Finished data.
5384 The function to register is gnutls_session_set_finished_function and
5385 it takes a callback of the gnutls_finished_callback_func type.
5387 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
5389 *** libgnutls: New interface to register a new TLS extension handler.
5390 The new function gnutls_ext_register can be used to register handlers
5391 for specific TLS extension types. The callback functions have the new
5392 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
5393 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
5396 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
5397 The function is gnutls_register_md5_handler. When libgcrypt is in
5398 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
5401 *** API/ABI changes in GnuTLS 2.6
5402 No functions have been removed or modified. The library should be
5403 fully backwards compatible on both the source and binary level.
5405 A new header file <gnutls/crypto.h> have been added. It contains
5406 definitions related to replacing the internal crypto functionality.
5407 All definitions and the header itself is experimental but supported.
5409 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
5410 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
5411 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
5413 The following functions have been added to libgnutls:
5417 gnutls_crypto_bigint_register2
5418 gnutls_crypto_cipher_register2
5419 gnutls_crypto_digest_register2
5420 gnutls_crypto_mac_register2
5421 gnutls_crypto_pk_register2
5422 gnutls_crypto_rnd_register2
5423 gnutls_crypto_single_cipher_register2

5437 gnutls_x509_crt_set_crl_dist_points2
5438 gnutls_x509_crt_set_subject_alt_name
5440 The following functions have been added to libgnutls-extra:
5442 gnutls_register_md5_handler
5444 ** API and ABI modifications:
5445 No changes since last version.
5447 * Version 2.5.9 (released 2008-09-29)
5449 ** libgnutls: Fix several memory leaks.
5450 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
5452 ** libgnutls: Fix buffer overrun in gnutls_x509_crt_list_import.
5453 Report and patch by Jonathan Manktelow.
5455 ** libgnutls: crypto.h gnutls_pk_params_st changes allocation strategy.
5456 The parameters are now allocated in the structure itself.
5458 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
5460 ** tests: Scripts now use EXEEXT properly.
5461 Modern libtool doesn't create wrapper script, so the self tests need
5462 to invoke certtool.exe under MinGW32+Wine.
5464 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
5465 Automake warnings are now also enabled.
5467 ** API and ABI modifications:
5468 gnutls_pk_params_st: MODIFIED
5470 * Version 2.5.8 (released 2008-09-21)
5472 ** certtool: updated so it can add several subject alternative names using
5475 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
5476 either set or append alternative names. It can also handle binary structures
5477 such as IP addresses.
5479 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
5481 ** libgnutls: New function to set minimum acceptable SRP bits.
5482 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick
5483 <quick@sparq.org> in <https://savannah.gnu.org/support/index.php?106454>.
5485 ** libgnutls: Check for overflows in gnutls_calloc and gnutls_secure_calloc.
5486 Also fix overflows in calls to those functions. Reported by Werner
5487 Koch <wk@gnupg.org>.
5489 ** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.

5502 gnutls_x509_crt_set_subject_alt_name: ADDED
5504 * Version 2.5.7 (released 2008-09-16)
5506 ** libgnutls: New interfaces to get name of public key and signing algorithms.
5507 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
5509 ** libgnutls: Don't crash when gnutls_credentials_set is called twice.
5511 ** libgnutls: Fix libgnutls shared library version.
5512 It wasn't properly incremented after adding symbols in the last
5515 ** manual: Now mention supported public key and public key signing algorithms.
5517 ** tests/openssl: initialize gnutls before use.
5519 ** tests/setcredcrash: New test to catch regressions of gnutls_credentials_set.
5521 ** GTK-DOC manual: mention new symbols in 2.6.x. Mention crypto.h functions.
5523 ** API and ABI modifications:
5524 gnutls_sign_get_name: ADDED
5525 gnutls_pk_get_name: ADDED
5527 * Version 2.5.6 (released 2008-09-08)
5529 ** libgnutls: Add interface to deal with public key and signature algorithms.
5530 The functions are called gnutls_pk_list, gnutls_pk_get_id,
5531 gnutls_sign_list, and gnutls_sign_get_id. Suggested by Sam
5532 Varshavchik <mrsam@courier-mta.com>.
5534 ** libgnutls: Refactor and clean up some code.
5536 ** libgnutls: Fix compile error with Sun CC.

5540 ** gnutls-cli, gnutls-serv: Remove --copyright parameter.
5541 Use standard --version to get license info.
5543 ** gnutls-cli.1: Document all new parameters.
5544 Thanks to James Westby <jw+debian@jameswestby.net>.
5546 ** tests: New self-test pgps2kgnu to test parsing of encrypted secrets.
5547 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.

5552 gnutls_sign_list: ADDED
5553 gnutls_sign_get_id: ADDED
5555 * Version 2.5.5 (released 2008-08-29)
5557 ** libgnutls: New API to get a string corresponding to a error symbol.
5558 The function is gnutls_strerror_name.
5560 ** libgnutls: Fix include paths so that building with internal libtasn1 works.
5561 Reported by "jth.net ApS" <info@jth.net>.
5563 ** libgnutls: Fix segmentation fault when generating private keys.
5564 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
5566 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
5567 The code has not worked since v0.9.0 and apparently nobody has missed
5568 it, so we decided to remove the code rather than fix it. If you have
5569 old certificate chains stored in PKCS#7 format, you can convert them
5570 to a list of PEM certificates by using 'certtool --p7-info'. Reported
5571 by Christian Grothoff <christian@grothoff.org>.
5573 ** opencdk: Parse (but not decrypt) encrypted secret keys.
5574 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
5576 ** libgnutls: Fix many warnings.
5578 ** Included copy of libtasn1 is upgraded to version 1.5.
5580 ** Add French translation, thanks to Nicolas Provost.
5582 ** API and ABI modifications:
5583 gnutls_strerror_name: ADDED
5585 * Version 2.5.4 (released 2008-08-19)
5587 ** Fix secure memory initialization of libgcrypt.
5588 Reported by Joe Orton <joe@manyfish.co.uk> in
5589 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2992>.
5592 Reference to NIST SP 800-57 in the manual on key size recommendations.
5593 Added 'Since:' tags to new APIs for gtk-doc.
5595 ** API and ABI modifications:
5596 No changes since last version.
5598 * Version 2.5.3 (released 2008-08-14)
5600 ** libgnutls: New API to set the public parameters in a certificate request
5601 ** from a private key.
5602 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
5603 discussion with "Zach C." <fxchip@gmail.com>.
5605 ** libgnutls: New API to set a callback to extract TLS Finished data.
5606 The function to register is gnutls_session_set_finished_function and
5607 it takes a callback of the gnutls_finished_callback_func type.
5609 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
5610 Reported in <https://savannah.gnu.org/support/?106453>.
5612 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
5613 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
5614 names are mapped to the new names in compat.h. These mappings will
5615 likely be removed more quickly than other mappings in that file due to
5616 the namespace violation.

5636 ** libgnutls: New interface to register a new TLS extension handler.
5637 The new function gnutls_ext_register can be used to register handlers
5638 for specific TLS extension types. The callback functions have the new
5639 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
5640 classify TLS extensions, gnutls_ext_parse_type_t, has been added as

5689 * Version 2.4.3 (released 2009-02-06)
5691 ** libgnutls: Accept chains where intermediary certs are trusted.
5692 Before GnuTLS needed to validate the entire chain back to a
5693 self-signed certificate. GnuTLS will now stop looking when it has
5694 found an intermediary trusted certificate. The new behaviour is
5695 useful when chains, for example, contains a top-level CA, an
5696 intermediary CA signed using RSA-MD5, and an end-entity certificate.
5697 To avoid chain validation errors due to the RSA-MD5 cert, you can
5698 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
5699 The signature on trusted certificates are not checked, so the chain
5700 has a chance to validate correctly. Reported by "Douglas E. Engert"
5701 <deengert@anl.gov> in
5702 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
5704 ** libgnutls: Permit V1 Certificate Authorities properly.
5705 Before they were mistakenly rejected even though
5706 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
5707 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by

5711 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
5712 This is a bugfix -- the previous attempt to do this from internal x509
5713 certificate verification procedures did not return the correct value
5714 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
5715 <dkg@fifthhorseman.net> in

5798 ** API and ABI modifications:
5799 No changes since last version.
5801 * Version 2.4.0 (released 2008-06-19)
5803 ** Major changes compared to the v2.2 branch:
5805 *** The OpenPGP sub-system has been improved and now supports subkeys.
5807 *** The PSK sub-system has been improved and now supports password
5808 *** derivation and PSK identity hints.
5809 The password derivation algorithms support is documented in
5810 draft-ietf-netconf-tls-02.txt.
5812 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
5813 This aligns terminology with OpenPGP, which doesn't use DER encoding.
5814 The old parameters will continue to work for some time.
5816 *** Certtool now confirm passwords and changes permissions of private key files.
5818 *** The default handshake size limit has been increased to 48kb.
5819 It appears as if some valid handshakes are large due to sending many
5820 CA certificates. (The earlier limit was 16kb.)
5822 *** LZO compression is now disabled by default.
5823 The main reason is that LZO compression in TLS is not standardized,
5824 but license compatiblity issues with minilzo triggered us to make this
5827 *** Improvements for cross-compilation to Windows and OpenWRT.
5829 *** The look of the GTK-DOC manual has been improved.
5830 Major developer visible changes compared to the v2.2 branch:
5832 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
5834 *** New APIs to access the raw X.509 Subject and Issuer DN's and
5835 *** elements from the certificate credentials structure.
5836 Thanks to Joe Orton.
5838 *** New APIs to improve working with username/passwords and PSK.
5840 *** Names of constants to affect certificate printing changed.
5841 The constants are used for OpenPGP too, which the names didn't
5842 reflect, so the following name change has been made:
5845 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
5846 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
5847 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
5849 The old names will be mapped to the new names for some time.
5851 *** The function gnutls_openpgp_privkey_get_id has been renamed to
5852 *** gnutls_openpgp_privkey_get_key_id.
5853 A compatibility mapping exists to avoid breaking API backwards
5856 *** Replaced all uses of alloca with malloc and free.
5858 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
5859 We have been unable to find a documented rationale for this practice.
5861 *** Of course, many smaller fixes have been made, see the ChangeLog file.
5863 *** API/ABI changes in GnuTLS 2.4
5864 All OpenPGP related functions have been moved from libgnutls-extra to
5865 libgnutls, and several new functions have been added (see below).
5866 Before making the release, we discussed whether moving functions from
5867 libgnutls-extra to libgnutls would require us to increment the ABI
5868 version, but the general opinion was that this would not be required.
5869 All older functions continue to work the same. We are open to the
5870 possibility that this decision will lead to problem on some platform,
5871 and if it turns out that the Right Thing should have been to increment
5872 the shared library version, we would need to release an update within
5873 the 2.4.x branch that increments the shared library version.
5875 This release adds the following functions:
5877 gnutls_psk_client_get_hint
5878 gnutls_psk_set_server_credentials_hint
5879 gnutls_psk_netconf_derive_key
5881 Used to get/set the PSK identity hint, and derive PSK keys from
5882 passwords a'la netconf.
5884 gnutls_x509_dn_deinit
5885 gnutls_x509_dn_export
5886 gnutls_x509_dn_import
5889 Used to handle X.509 Certificate DN's directly.
5893 Converts a data buffer to hex. Useful for handling PSK/SRP shared
5896 gnutls_certificate_get_x509_cas
5897 gnutls_certificate_get_x509_crls
5898 gnutls_certificate_get_openpgp_keyring
5900 Functions for direct access to credential elements.

5940 gnutls_openpgp_privkey_get_subkey_revoked_status
5941 gnutls_openpgp_privkey_set_preferred_key_id
5943 New OpenPGP related functions.
5945 The function gnutls_openpgp_crt_get_key_id is the same as the old
5946 from gnutls_openpgp_crt_get_id, see above.
5948 The release also adds a new header file 'gnutls/crypto.h', however it
5949 is currently not used.

5983 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
5985 ** doc/: Add psktool to info index. Some minor cleanups.
5987 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
5989 ** tests/: Added libgcrypt.supp which can be used with valgrind.
5990 The file suppresses the known libgcrypt memory leaks, so they aren't
5991 printed when you run valgrind on the gnutls self-tests. Use it as
5992 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add

6013 The function is gnutls_psk_client_get_hint.
6015 *** libgnutls [PSK]: New API to set PSK identity hint in server.
6016 The function is gnutls_psk_set_server_credentials_hint.
6018 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
6019 In the client, the message is parsed and the application can use
6020 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
6021 message is sent if the application has specified a PSK identity hint
6022 using gnutls_psk_set_server_credentials_hint.
6024 *** libgnutls [PSK]: Support Netconf PSK key derivation.
6025 The function gnutls_psk_netconf_derive_key supports the PSK key
6026 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
6029 *** psktool: Support new --netconf-hint to generate PSK key from password.
6030 Uses the Netconf algorithm to derive PSK key from password.
6032 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
6034 *** gnutls-cli: Always support PSK modes, through a callback.
6035 The callback will derive a PSK key using Netconf algorithm. It will
6036 print the PSK identity hint to help the user.
6038 *** New PSK example client and server.
6039 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
6041 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.

6129 Also improve manual to give example for gnutls-cli PSK authentication.
6131 ** certtool: Encrypting a private key now require a confirmed password.
6132 Before './certtool -k -8' would merely ask for a password once.
6133 Reported by Daniel 'NebuchadnezzaR' Dehennin
6134 <nebuchadnezzar@asgardr.info> see
6135 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
6137 ** certtool: When writing private keys to files, change permissions of file.
6138 Now the file which the private key is saved to is chmod'ed 0600.
6139 Reported by martin f krafft <madduck@debian.org> see
6140 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
6142 ** guile: Fix -fgnu89-inline test.
6144 ** Removed --enable-profile-mode.
6145 The code linked gnutls with the libfc project (Function Check) which
6146 appears to have been stalled since around 2002.
6148 ** Clean up header file checks by ./configure.
6150 ** Update of gnulib files.
6152 ** API and ABI modifications:
6153 No changes since last version.
6155 * Version 2.3.8 (released 2008-04-29)
6157 ** libgnutls: Increase default handshake packet size limit to 48kb.
6158 The old limit was 16kb and some servers send huge list of trusted CAs,
6159 thus running into the limit. FYI, applications can further increase
6160 this limit using gnutls_handshake_set_max_packet_length. Thanks to
6161 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
6162 <marc@mclemente.net> for reporting and providing test servers.
6164 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
6165 Returned when the handshake data size is too large. Before
6166 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
6169 ** libgnutls: Hide definitions in crypto.h.
6170 We have decided that the APIs defined in crypto.h are not stable
6171 enough for v2.4, so don't use any of those functions.
6173 ** gnutls-cli: exit when hostname doesn't match certificate.
6174 Use --insecure to avoid hostname comparison.
6176 ** certtool: --inder and --outder replaced by --inraw and --outraw.
6177 The reason is to align terminology with OpenPGP, which doesn't use
6178 DER. The old parameters will continue to work for some time.
6180 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
6182 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
6184 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
6185 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
6186 vasprintf symbol from the libgcrypt library which caused problems.
6188 ** Update of gnulib files.
6190 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
6192 ** API and ABI modifications:
6193 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
6195 * Version 2.3.7 (released 2008-04-21)
6197 ** opencdk now properly sets the key usage bits into openpgp keys.
6199 ** gnutls-cli: Fix crash on TLS handshake failures.
6200 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
6201 This is similar to <http://bugs.debian.org/429183>.
6203 ** certtool: with --generate-request and newly generated keys, print the key.
6205 ** Build fixes for MinGW.
6206 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
6207 with -lws2_32 when needed. Use ASCII only isprint() when printing
6208 X.509 certificate information, to avoid non-ASCII but printable
6209 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
6212 ** Update internal copy of libtasn1 to version 1.4.
6214 ** API and ABI modifications:
6215 No changes since last version.
6217 * Version 2.3.6 (released 2008-04-17)
6219 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
6220 ** Improve documentation for gnutls_x509_crq_sign2.
6221 Based on report from "John Brooks" <aspecialj@gmail.com> in
6222 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
6224 ** tests/pathlen: run diff without parameters to improve portability.
6225 Based on HPUX build hints in
6226 <http://hpux.cs.utah.edu/hppd/cgi-bin/wwwtar?/hpux/Gnu/gnutls-2.3.4/gnutls-2.3.4-src-11.11.tar.gz+gnutls-2.3.4/HPUX.Install+text>.
6228 ** Don't use %e specifier with strftime, it doesn't work under Windows.
6229 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
6230 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
6232 ** Remove all uses of gnutls_alloca/gnutls_afree.
6233 Use normal gnutls_malloc instead. One reason is increased portability
6234 to Windows, the other is that several of the uses may be unsafe
6235 because the size of data allocated could be large. Reported by
6236 Massimo Gaspari <massimo.gaspari@alice.it> in
6237 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
6239 ** Build Guile code with -fgnu89-inline only when supported.
6240 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
6241 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
6243 ** Several GTK-DOC related fixes.
6245 ** Clean up OpenCDK related code.
6246 GnuTLS now requires its internal OpenCDK code rather than the external
6247 GPL library OpenCDK. Unfortunately, we don't have resources to
6248 maintain an external library (help welcome).
6250 ** API and ABI modifications:
6251 No changes since last version.
6253 * Version 2.3.5 (released 2008-04-14)
6255 ** Build fix for MinGW and --disable-shared.
6256 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
6257 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
6259 ** Document how to generate CRLs.
6260 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
6262 ** Documented the --priority option to gnutls-cli and gnutls-serv.
6264 ** Several minor fixes in the OpenPGP interface.
6265 Thanks to Daniel Kahn Gillmor.
6267 ** Fix fopen file descriptor leak in PSK server code.
6268 Thanks to Laurence Withers <l@lwithers.me.uk>, see
6269 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
6271 ** Translations files not stored directly in git to avoid merge conflicts.
6273 ** New APIs to let applications replace the RNG used.
6274 Update all RNG callers in the code to use the new interface.
6276 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
6278 ** Update gnulib files.
6280 ** API and ABI modifications:
6281 gnutls_crypto_rnd_register: ADDED
6282 gnutls_rnd_level_t: ADDED
6283 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
6284 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
6285 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
6286 gnutls_crypto_rnd_st: ADDED
6287 GNUTLS_DIG_SHA224: ADDED
6288 GNUTLS_SIGN_RSA_SHA224: ADDED
6289 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
6291 * Version 2.3.4 (released 2008-03-19)
6293 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
6294 They weren't renamed in the public header file.
6296 ** Added functions to register a cipher/mac/digest. This allows to
6297 override the included ones.
6299 ** Fix a bunch of compiler warnings.
6301 ** API and ABI modifications:
6302 gnutls_crypto_cipher_st: ADDED
6303 gnutls_crypto_mac_st: ADDED
6304 gnutls_crypto_digest_st: ADDED
6305 gnutls_crypto_cipher_register: ADDED
6306 gnutls_crypto_mac_register: ADDED
6307 gnutls_crypto_digest_register: ADDED
6308 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
6310 * Version 2.3.3 (released 2008-03-10)
6312 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
6313 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
6315 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
6316 We could not find any modern justification for enabling these flags by
6317 default. If you know of some platform that needs one of the flags to
6318 work properly, please let us know. (Actually introduced in v2.3.0 but
6319 not documented until now.)
6321 ** Importing many CA certificates are now considerably faster.
6322 This affect gnutls_certificate_set_x509_trust_mem,
6323 gnutls_certificate_set_x509_trust, and
6324 gnutls_certificate_set_x509_trust_file. The complexity was reduced
6325 from O(2*n^2) to O(n). When adding 206 files containing 408
6326 certificates, using gnutls_certificate_set_x509_trust_file, the time
6327 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
6328 to trigger the problem. See also
6329 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
6331 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
6332 ** to be explicit that it takes zero terminated data.
6334 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
6336 ** Documentation fixes for the GTK-DOC manual.
6338 ** Fix compilation error related to __FUNCTION__ on some systems.
6339 Reported by Tim Mooney, see
6340 <https://savannah.gnu.org/support/?106267>.
6342 ** Updated translations.
6344 ** Update gnulib files.
6346 ** API and ABI modifications:
6347 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
6348 and char* instead of void* for output buffer.
6350 * Version 2.3.2 (released 2008-02-26)
6352 ** Fix srcdir!=objdir failure in openpgpself test.
6354 ** Improved API documentation output from GTK-DOC.
6356 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
6358 ** Renamed gnutls_certificate_export_x509_cas and friends.
6359 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
6361 ** Internal header files cleanup.
6363 ** API and ABI modifications:
6364 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
6365 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
6366 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
6367 gnutls_x509_dn_export: ADDED
6369 * Version 2.3.1 (released 2008-02-21)
6371 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
6372 The included copy of OpenCDK has been stripped down and re-licensed
6375 ** Cipher priority string handling now handle strings that starts with NULL.
6376 Thanks to Laurence Withers <l@lwithers.me.uk>.
6378 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
6380 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
6383 ** Increased the default certificate verification chain limits and allowed
6384 for checks without limitation.
6386 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
6387 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
6388 strings and return the proper size.
6390 ** Add section 'On Record Padding' to the manual.
6391 This collects all problems related to record padding with
6392 Nokia/Sony-Ericsson phones that we know about.
6394 ** Several improvements in the OpenPGP authentication.
6395 Now subkeys can be used for authentication, according to
6396 draft-mavrogiannopoulos-rfc5081bis-00.txt.
6398 ** certtool can print information on OpenPGP certificates and keys.
6400 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
6403 ** Added gnutls_certificate_export_x509_cas and other functions to
6404 export elements from the certificate credentials structure. Based on
6405 suggestion from Joe Orton.
6408 Clarify that srp_base64 is not the same as normal base64.
6410 ** Fix non-portable use of brace expansion in makefiles.
6412 ** API and ABI modifications:
6413 gnutls_certificate_export_x509_cas: ADDED
6414 gnutls_certificate_export_x509_crls: ADDED
6415 gnutls_certificate_export_openpgp_keyring: ADDED
6416 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
6417 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
6418 gnutls_openpgp_crt_get_revoked_status: ADDED
6419 gnutls_openpgp_crt_get_subkey_count: ADDED
6420 gnutls_openpgp_crt_get_subkey_idx: ADDED
6421 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
6422 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
6423 gnutls_openpgp_crt_get_subkey_creation_time: ADDED
6424 gnutls_openpgp_crt_get_subkey_expiration_time: ADDED
6425 gnutls_openpgp_crt_get_subkey_id: ADDED
6426 gnutls_openpgp_crt_get_subkey_usage: ADDED
6427 gnutls_openpgp_privkey_get_fingerprint: ADDED

6454 GNUTLS_CRT_PRINT_ONELINE: ADDED, same as old GNUTLS_X509_CRT_ONELINE.
6455 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
6456 old GNUTLS_X509_CRT_UNSIGNED_FULL.
6458 * Version 2.3.0 (released 2008-01-08)
6460 ** LZO compression is now disabled by default.
6461 The reason is that LZO compression is not standardized in TLS. If you
6462 wish to experiment with it, you will have to supply --with-lzo when
6463 invoking ./configure. The internal copy of minilzo is no longer
6464 included with GnuTLS, so you will need to install liblzo or liblzo2 on
6465 your system to have --with-lzo to be effective.
6467 ** More than one server name field is now sent to the server properly.
6468 Thanks to mark.phillips@virgin.net.
6470 ** Fixes the post_client_hello_function(). The extensions are now parsed
6471 in a callback friendly way.
6473 ** Fix for certificate selection in servers with certificate callbacks.
6475 ** Updated translations.
6477 ** Update gnulib files.
6479 ** API and ABI modifications:
6480 No changes since last version.
6482 * Version 2.2.5 (released 2008-05-19)
6484 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
6485 The flaw would result in incorrectly terminated sessions with the
6486 error "Decryption has failed" when the server sends a small packet
6487 (typically when the session is closed). Reported by Andreas Metzler
6488 <ametzler@downhill.at.eu.org> in

6491 ** API and ABI modifications:
6492 No changes since last version.
6494 * Version 2.2.4 (released 2008-05-19)
6496 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
6497 Thanks to CERT-FI for finding the bugs and providing detailed reports,
6498 which allowed the bugs to be reproduced and fixed easily. Patches
6499 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
6500 with more details about these vulnerabilities will be added to

6503 *** [GNUTLS-SA-2008-1-1]
6504 *** libgnutls: Fix crash when sending invalid server name.
6505 The crash can be triggered remotely before authentication, which can
6506 lead to a Daniel of Service attack to disable the server. The bug
6507 cause gnutls to store more session resumption data than what was
6508 allocated for, thus overwriting unallocated memory.
6510 *** [GNUTLS-SA-2008-1-2]
6511 *** libgnutls: Fix crash when sending repeated client hellos.
6512 The crash can be triggered remotely before authentication, which can
6513 lead to a Daniel of Service attack to disable the server. The bug
6514 triggers a null-pointer dereference.
6516 *** [GNUTLS-SA-2008-1-3]
6517 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
6518 The crash can be triggered remotely before authentication, which can
6519 lead to a Daniel of Service attack to disable the server. The bug
6520 cause gnutls to read memory beyond the end of the received record.
6522 ** API and ABI modifications:
6523 No changes since last version.
6525 * Version 2.2.3 (released 2008-05-06)
6527 ** Increase default handshake packet size limit to 48kb.
6528 The old limit was 16kb and some servers send huge list of trusted CAs,
6529 thus running into the limit. FYI, applications can further increase
6530 this limit using gnutls_handshake_set_max_packet_length. Thanks to

6550 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
6552 ** API and ABI modifications:
6553 No changes since last version.
6555 * Version 2.2.2 (released 2008-02-21)
6557 ** Cipher priority string handling now handle strings that starts with NULL.
6558 Thanks to Laurence Withers <l@lwithers.me.uk>.
6560 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
6563 ** Increased the default certificate verification chain limits and allowed

6566 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
6567 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
6568 strings and return the proper size.
6570 ** API and ABI modifications:
6571 No changes since last version.
6573 * Version 2.2.1 (released 2008-01-17)
6575 ** Prevent linking libextra against previously installed libgnutls.
6576 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
6577 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
6579 ** Fixes the post_client_hello_function(). The extensions are now parsed
6580 in a callback friendly way.
6582 ** Fix for certificate selection in servers with certificate callbacks.
6584 ** API and ABI modifications:
6585 No changes since last version.
6587 * Version 2.2.0 (released 2007-12-14)
6589 ** Update internal copy of libtasn1 to version 1.2.
6591 ** Certtool --verify-chain now handle inputs larger than 64kb.
6592 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
6593 recent versions of libgcrypt. The problem was that Wine with the
6594 libgcrypt RNG generates huge amounts of debugging output.
6596 ** Translation updates.
6597 Added Dutch translation. Updated Polish and Swedish translation.
6599 ** Major changes compared to the v2.0 branch:
6601 *** SRP support aligned with newly published RFC 5054.
6603 *** OpenPGP support aligned with newly published RFC 5081.
6605 *** Support for DSA2 keys.
6607 *** Support for Camellia cipher.
6609 *** Support for Opaque PRF Input extension.
6611 *** PKCS#8 parser now handle DSA keys.
6613 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
6614 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
6615 versions, such as 2.01 which is included with GnuTLS, is available
6616 under GPLv2 or later. If this incompatibility causes problems, we
6617 recommend you to disable LZO using --without-lzo. LZO compression is
6618 not a standard TLS compression algorithm, so the impact should be
6621 *** Functions for disabling record protocol padding.
6622 Works around bugs on Nokia/Ericsson phones.
6624 *** New functions gnutls_priority_set() for setting cipher priorities easily.
6625 Priorities like "COMPAT" also enables other work arounds, such as
6628 *** Other minor improvements and bug fixes.
6630 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
6631 To adapt to changes in the TLS extension specifications for OpenPGP
6632 and SRP, the GnuTLS API had to be modified. This means breaking the
6633 API and ABI backwards compatibility. That is something we try to
6634 avoid unless it is necessary. We decided to also remove the already
6635 deprecated stub functions for X.509 to XML conversion and TLS
6636 authorization (see below) when we had the opportunity.
6638 Generally, most applications does not need to be modified. Just
6639 re-compile them against the latest GnuTLS release, and it should work
6642 Applications that use the OpenPGP or SRP features needs to be
6643 modified. Below is a list of the modified APIs and discussion of what
6644 the minimal things you need to modify in your application to make it
6645 work with GnuTLS 2.2.
6647 Note that GnuTLS 2.2 also introduces new APIs -- such as
6648 gnutls_set_priority() that is superior to
6649 gnutls_set_default_priority() -- that you may want to start using.
6650 However, using those new APIs is not required to use GnuTLS 2.2 since
6651 the old functions continue are still supported. This text only
6652 discuss what you minimally have to modify.
6654 *** XML related changes
6655 The function `gnutls_x509_crt_to_xml' has been removed. It has been
6656 deprecated and only returned an error code since GnuTLS version
6657 1.2.11. Nobody has complained, so users doesn't seem to miss the
6658 functionality. We don't know of any other library to convert X.509
6659 certificates into XML format, but we decided (long ago) that GnuTLS
6660 isn't the right place for this kind of functionality. If you want
6661 help to find some other library to use here, please explain and
6662 discuss your use case on help-gnutls@gnu.org.
6664 *** TLS Authorization related changes
6665 Everything related to TLS authorizations have been removed, they were
6666 only stub functions that returned an error code:
6668 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
6669 gnutls_authz_data_format_type_t
6670 gnutls_authz_recv_callback_func
6671 gnutls_authz_send_callback_func
6673 gnutls_authz_send_x509_attr_cert
6674 gnutls_authz_send_saml_assertion
6675 gnutls_authz_send_x509_attr_cert_url
6676 gnutls_authz_send_saml_assertion_url
6678 *** SRP related changes
6679 The callback gnutls_srp_client_credentials_function has a new
6680 prototype, and its semantic has changed. You need to rewrite the
6681 callback, see the updated function documentation and SRP example code
6682 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
6685 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
6686 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
6687 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
6688 used. There are #define's to map the old names to the new. You may
6689 run into problems if you have a switch-case with cases for both SRP
6690 alerts, since they are now mapped to the same value. The solution is
6691 to drop the SRP alerts from such switch cases, as they are now
6692 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
6694 *** OpenPGP related changes
6695 The function `gnutls_certificate_set_openpgp_keyserver' have been
6696 removed. There is no replacement functionality inside GnuTLS. If you
6697 need keyserver functionality, consider using the GnuPG tools.
6699 All functions, types, and error codes related to OpenPGP trustdb
6700 format have been removed. The trustdb format is a non-standard
6701 GnuPG-specific format, and we recommend you to use key rings instead.
6702 The following have been removed:
6704 gnutls_certificate_set_openpgp_trustdb
6705 gnutls_openpgp_trustdb_init
6706 gnutls_openpgp_trustdb_deinit
6707 gnutls_openpgp_trustdb_import
6708 gnutls_openpgp_key_verify_trustdb
6709 gnutls_openpgp_trustdb_t
6710 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
6712 The following functions has an added parameter of the (new) type
6713 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
6714 (binary or base64). The functions are:
6715 gnutls_certificate_set_openpgp_key_file
6716 gnutls_certificate_set_openpgp_key_mem
6717 gnutls_certificate_set_openpgp_keyring_mem
6718 gnutls_certificate_set_openpgp_keyring_file
6720 To improve terminology and align with the X.509 interface, some
6721 functions have been renamed. Compatibility mappings exists. The old
6722 and new names of the affected functions and types are:
6725 gnutls_openpgp_key_t gnutls_openpgp_crt_t
6726 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
6727 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
6728 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
6729 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
6730 gnutls_openpgp_key_init gnutls_openpgp_crt_init
6731 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit
6732 gnutls_openpgp_key_import gnutls_openpgp_crt_import
6733 gnutls_openpgp_key_export gnutls_openpgp_crt_export
6734 gnutls_openpgp_key_get_key_usage gnutls_openpgp_crt_get_key_usage
6735 gnutls_openpgp_key_get_fingerprint gnutls_openpgp_crt_get_fingerprint
6736 gnutls_openpgp_key_get_pk_algorithm gnutls_openpgp_crt_get_pk_algorithm
6737 gnutls_openpgp_key_get_name gnutls_openpgp_crt_get_name
6738 gnutls_openpgp_key_get_version gnutls_openpgp_crt_get_version
6739 gnutls_openpgp_key_get_creation_time gnutls_openpgp_crt_get_creation_time
6740 gnutls_openpgp_key_get_expiration_time gnutls_openpgp_crt_get_expiration_time
6741 gnutls_openpgp_key_get_id gnutls_openpgp_crt_get_id
6742 gnutls_openpgp_key_check_hostname gnutls_openpgp_crt_check_hostname
6743 gnutls_openpgp_send_key gnutls_openpgp_send_cert
6745 ** API and ABI modifications:
6746 No changes since last version.
6748 * Version 2.1.8 (released 2007-12-10)
6750 ** The GPL version has been changed from version 2 to version 3.
6751 This affects the self-tests, command-line tools, the libgnutls-extra
6752 library, the relevant guile parts, and the build environment.
6754 ** Added gnutls_x509_crt_get_subject_alt_name2().
6756 ** Corrected a segfault when setting an empty gnutls_priority_t
6757 at gnutls_priority_set().

6767 ** PKCS #8 parser can now encode/decode DSA keys.
6769 ** Updated gnutls_set_default_priority2() now renamed to
6770 gnutls_priority_set() and gnutls_priority_set_direct() which
6771 accept a string to indicate preferences of ciphersuite parameters.
6773 ** gnutls-cli and gnutls-serv now have a --priority option to set
6774 the priority string.
6776 ** The gnutls_*_convert_priority() functions were deprecated by
6777 the gnutls_priority_set() and gnutls_priority_set_direct().
6779 ** Internal copy of OpenCDK upgraded to version 0.6.6.
6781 ** API and ABI modifications:

6812 * Version 2.1.6 (released 2007-11-15)
6814 ** Corrected bug in decompression of expanded compression data.
6816 ** Added the --to-p8 option to certtool to convert private keys
6819 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
6821 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
6824 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
6825 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
6826 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
6827 documented. This caused some problems (e.g., debian #450854). To
6828 avoid backwards compatibility problems, this release revert this
6829 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
6830 done in GnuTLS 2.0.x and earlier, and add a new error code
6831 GNUTLS_E_UNKNOWN_ALGORITHM.
6833 ** Fixes several gtk-doc warnings.
6835 ** API and ABI modifications:
6836 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
6837 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
6838 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
6840 * Version 2.1.5 (released 2007-11-01)
6842 ** Fix PKCS#3 parameter export problem.
6844 ** Improve certtool queries, they now print the default value.
6848 ** Update gnulib files.
6850 ** API and ABI modifications:
6851 No changes since last version.
6853 * Version 2.1.4 (released 2007-10-27)
6855 ** Added the --v1 option to certtool, to allow generating X.509
6856 version 1 certificates.
6858 ** certtool: Add option --disable-quick-random to enable the old behaviour
6859 of using /dev/random to generate keys.
6861 ** Added priority functions that accept strings.
6863 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
6864 priorities preferences.
6866 ** Added gnutls_record_disable_padding() to allow servers talking to
6867 buggy clients that complain if the TLS 1.0 record protocol padding is
6870 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
6871 all supported compatibility options (like disabling padding).
6873 ** The gnutls_certificate_set_openpgp_* functions were modified to include
6874 the format. This makes the interface consistent with the x509 functions.
6876 ** Internal copy of OpenCDK upgraded to version 0.6.5.
6878 ** Update gnulib files.

6917 ** TLS authorization support removed.
6918 This technique may be patented in the future, and it is not of crucial
6919 importance for the Internet community. After deliberation we have
6920 concluded that the best thing we can do in this situation is to
6921 encourage society not to adopt this technique. We have decided to
6922 lead the way with our own actions.
6924 ** Re-enabled the 256 bit ciphers in the default priorities.

6939 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
6940 gnutls_supplemental_data_format_type_t enum type becomes empty.
6942 * Version 2.1.2 (released 2007-10-14)
6944 ** Removed all the trustdb code from openpgp authentication.
6945 We now use only the well-specified keyrings.
6947 ** The 256 bit ciphers are not enabled in the default priorities.
6949 ** Added support for DSA2 using libgcrypt 1.3.0.
6951 ** certtool: Fixed data corruption when using --outder.
6953 ** Removed all the xml related stubs and functions.

6984 * Version 2.1.1 (released 2007-09-24)
6986 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
6987 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
6988 compiled with Camellia support. See the libgcrypt documentation on
6989 how to enable it. Unconditionally disable it using the configure
6990 option --disable-camellia. Fixes #1.
6992 ** Properly document in the NEWS file the API change in the last release.
6994 ** API and ABI modifications:
6995 No changes since last version.
6997 * Version 2.1.0 (released 2007-09-20)
6999 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
7000 The support is disabled by default. Since no value has been allocated
7001 by the IANA for this extension yet, you will need to provide one
7002 yourself by invoking './configure --enable-opaque-prf-input=42'.

7043 importance for the Internet community. After deliberation we have
7044 concluded that the best thing we can do in this situation is to

7046 lead the way with our own actions.
7048 ** certtool: Fixed data corruption when using --outder.
7050 ** Fix configure-time Guile detection.
7052 ** API and ABI modifications:
7053 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
7054 gnutls_supplemental_data_format_type_t enum type becomes empty.
7056 * Version 2.0.1 (released 2007-09-20)
7058 ** New directory doc/credentials/ with test credentials.
7059 This collects the test credentials from the web page and from src/.
7060 The script gnutls-http-serv has also been moved to that directory.
7062 ** Update SRP extension type and cipher suite with official IANA values.
7063 This breaks backwards compatibility with SRP in older versions of
7064 GnuTLS, but this is intentional to speed up the adoption of the
7065 official values. The old values we used were incorrect.
7067 ** Guile: Fix `x509-certificate-dn-oid'
7069 ** API and ABI modifications:
7070 No changes since last version.
7072 * Version 2.0.0 (released 2007-09-04)
7074 ** Included copy of Libtasn1 upgraded to version 1.1.
7076 ** Disable building of some examples if anonymous ciphers are disabled.
7078 ** Don't build examples for disabled features.
7080 ** API and ABI modifications:
7081 No changes since last version.
7083 * Version 1.7.19 (released 2007-08-27)
7085 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
7086 This solves connection problems in mutt, see
7087 <http://bugs.debian.org/439640>.
7089 ** Update gnulib files.
7090 In particular, the getpass module -- with its dependencies on getline,
7091 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
7092 library) directory to the gl/ directory (only used by the command line
7093 tools). The reason is that getpass is now only used by the
7094 command-line tools, and reducing the number of gnulib modules linked
7095 to the core library helps portability and reduces size.
7099 ** Disable building of PGP examples if PGP is disabled.
7101 ** Included copy of OpenCDK upgraded to version 0.6.4.
7103 ** API and ABI modifications:
7104 No changes since last version.
7106 * Version 1.7.18 (released 2007-08-16)
7108 ** Install images for the info manual.
7109 This has a side effect of renaming the images. See
7110 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
7111 discussions on the approach chosen.
7113 ** Fix pointer mix to variables of different size.
7114 Patch extracted from
7115 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
7117 ** Fix warnings during build.
7118 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
7120 ** API and ABI modifications:
7121 No changes since last version.
7123 * Version 1.7.17 (released 2007-08-15)
7125 ** New functions to perform external signing.
7126 Set the signing callback function (of the gnutls_sign_func prototype)
7127 using the gnutls_sign_callback_set function. In the callback, you may
7128 find the new functions gnutls_x509_privkey_sign_hash and
7129 gnutls_openpgp_privkey_sign_hash useful. A new function
7130 gnutls_sign_callback_get is also added, to retrieve the function
7131 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
7132 comments and testing.
7134 ** New self test of client and server authenticated X.509 TLS sessions.
7135 See tests/x509self.c and tests/x509signself.c. The latter also tests
7136 the new external signing callback interface.
7138 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
7139 These two actually describe the outer limits of a range of error codes
7140 reserved to the application. All of the errors are treated as fatal
7141 by the library (it has to since it doesn't know the semantics of the
7142 error codes). This can be useful in callbacks, to signal some
7143 application-specific error condition, which will usually eventually
7144 cause some gnutls API to return the same error code as the callback,
7145 which then can be inspected by the application. Note that error codes
7148 ** gnutls_set_default_priority now disable TLS 1.2 by default.
7149 The RFC is not released yet, and we're approaching a major release so
7150 let's not enable it just yet.
7152 ** Fix namespace so that gnutls_*_t is used consistently.
7153 Before, many places in the GnuTLS code used the old deprecated type
7154 names without the '_t' suffix.
7156 ** Build fixes for Guile code.
7157 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
7159 ** More documentation fixes.
7160 In particular, the section headings were modified for casing. By
7161 Ludovic Courtes <ludovic.courtes@laas.fr>.
7163 ** Updated Polish and Swedish translations.
7164 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
7165 <po@danielnylander.se>.
7167 ** API and ABI modifications:
7168 gnutls_sign_func: ADD, new type for sign callback.
7169 gnutls_sign_callback_set: ADD, new function to set sign callback.
7170 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
7171 gnutls_x509_privkey_sign_hash,
7172 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
7173 GNUTLS_E_APPLICATION_ERROR_MIN,
7174 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
7176 * Version 1.7.16 (released 2007-08-07)
7178 ** Fix sanity checks and return values in certificate selection.
7179 In some cases, GnuTLS omitted to report suitable error codes when no
7180 suitable certificate was found.
7182 ** Fix gnutls-cli starttls EOF on Mac OS X.
7183 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
7185 ** Documentation fixes.
7186 In particular, the section headings were modified for casing. By
7187 Ludovic Courtes <ludovic.courtes@laas.fr>.
7189 ** Update gnulib files.
7191 ** API and ABI modifications:
7192 No changes since last version.
7194 * Version 1.7.15 (released 2007-07-02)
7196 ** Fix self-tests key-id under mingw32.
7198 ** Test that the Guile header files are recent enough to work.
7199 Before we just tested that the command line tool 'guile' was recent
7200 enough, which may not be sufficient if you still have an old
7201 libguile.h header installed.
7203 ** Guile bindings are now installed under $prefix by default.
7204 Use --without-guile-site-dir to install it under $pkgdatadir/site/
7205 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
7206 Use --with-guile-site-dir=/your/own/path to specify the path manually.
7207 The default, --with-guile-site-dir, will install the Guile bindings
7208 under $datadir/guile/site. There is a new section 'Guile
7209 Preparations' in the manual that discuss these issues.
7211 ** Fix run-time library path ordering in linking the Guile bindings.
7213 ** Improved manual on downloading, installing, getting help, bug reports etc.
7214 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
7216 ** Add Malay message translations.
7217 Thanks to Sharuzzaman Ahmat Raslan <sharuzzaman@myrealbox.com>.
7219 ** API and ABI modifications:
7220 No changes since last version.
7222 * Version 1.7.14 (released 2007-06-26)
7224 ** Don't enable Guile bindings unless we have Guile 1.8 or later.
7225 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
7227 ** Fix memory leak during DSA signature verification.

7248 No changes since last version.
7250 * Version 1.7.13 (released 2007-06-11)
7252 ** OpenCDK copy updated to version 0.6.3.
7254 ** Build fixes for GnuTLS Guile bindings.
7255 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
7257 ** Build fix for GTK-DOC manual.
7259 ** Update gnulib files.
7261 ** API and ABI modifications:
7262 No changes since last version.
7264 * Version 1.7.12 (released 2007-06-08)
7266 ** Guile bindings for GnuTLS have been included.
7267 Contributed by Ludovic Courtès <ludovic.courtes@laas.fr>. There is a
7268 new chapter 'Guile Bindings' in the manual.
7270 ** Have PKCS8 parser return better error codes.
7271 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
7272 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
7273 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
7275 ** Fix mem leak for sessions with client authentication via certificates.
7276 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
7277 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
7280 Reported by Dennis Vshivkov <walrus@amur.ru>, see
7281 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
7282 self-test tests/parse_ca.c to test regressions.
7284 ** Fix build failures related to missing images in manual.
7285 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
7287 ** Update gnulib files.
7289 ** API and ABI modifications:
7290 No changes since last version.
7292 * Version 1.7.11 (released 2007-05-26)
7294 ** Include opencdk.h in the release.
7295 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
7297 ** API and ABI modifications:
7298 No changes since last version.
7300 * Version 1.7.10 (released 2007-05-25)
7302 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
7303 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
7305 ** Update of gnulib files.
7307 ** GnuTLS is now developed in GIT instead of CVS.
7308 See <http://repo.or.cz/w/gnutls.git> for a public repository.
7310 ** API and ABI modifications:
7311 gnutls_x509_crt_get_raw_issuer_dn: ADD.
7312 gnutls_x509_crt_get_raw_dn: ADD.
7314 * Version 1.7.9 (released 2007-05-12)
7316 ** X.509 certificates are preferred over OpenPGP keys.
7317 This is a change in the semantics of gnutls_set_default_priority.
7319 ** The included copy of OpenCDK has been updated to 0.6.1.
7320 There has been some API changes in OpenCDK, and the GnuTLS layer have
7321 been modified as well. Note that while there are API/ABI incompatible
7322 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
7323 its API/ABI have not changed. From this version on, GnuTLS requires
7324 OpenCDK 0.6.0 or later.
7326 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
7328 ** Change certtool's default serial number from 0 to a time-based value.
7330 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
7331 Before, we remove the parameters field, which resulted in a slightly
7332 different DER encoding which in turn caused signature verification
7333 failures of GnuTLS-generated RSA certificates in some other
7334 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
7335 you read, this may or may not be correct, but our new behaviour appear
7336 to be consistent with other widely used implementations.
7338 ** Fix mem leaks in gnutls_x509_crt_print.
7340 ** API and ABI modifications:
7341 No changes since last version.
7343 * Version 1.7.8 (released 2007-04-16)
7345 ** Added examples for the authorization extension.
7346 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
7348 ** The examples only use gnutls_set_default_priority().
7349 The exception is when DH_ANON is needed.
7351 ** Improve gnutls_set_default_priority() priorities.
7352 The new approach is for it to try and negotiate all secure and
7353 standard mechanisms available. Currently, DH_ANON ciphersuites and
7354 LZO compressions are not enabled by default, because they are,
7355 respectively, insecure and non-standardized. Note that TLS 1.2 will
7356 not be enabled by default in non-experimental release until it has
7357 been approved by the IETF.
7359 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
7360 This means that to get DH_ANON and LZO compression, you'll need to
7361 specify that manually using '--kx anon' or '--comp lzo'.
7363 ** Minor fixes to the human display format of X.509 certificates.
7365 ** New APIs to extract Distinguished Name's from X.509 certificates.
7366 Based on patch from Howard Chu <hyc@symas.com>.
7368 ** Improved library searching for opencdk.
7369 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
7370 The deprecated opencdk.m4 is no longer used.
7372 ** New APIs to list supported algorithms in the library.
7373 The APIs are gnutls_cipher_list, gnutls_mac_list,
7374 gnutls_compression_list, gnutls_protocol_list,
7375 gnutls_certificate_type_list, gnutls_kx_list, and
7376 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
7378 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
7380 ** New configure option --disable-tls-authorization to disable tls-authz.
7382 ** Fix prototype for `gnutls_psk_set_client_credentials'.
7383 The last parameter was renamed from 'flags' to 'format' and the type
7384 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
7385 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
7388 ** Fix allocation in gnutls_certificate_set_openpgp_key.
7389 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
7391 ** API and ABI modifications:
7392 gnutls_x509_dn_t: ADD.
7393 gnutls_x509_ava_st: ADD.
7394 gnutls_x509_crt_get_subject,
7395 gnutls_x509_crt_get_issuer: ADD.
7396 gnutls_x509_dn_get_rdn_ava: ADD.
7397 gnutls_cipher_list: ADD.
7398 gnutls_mac_list: ADD.
7399 gnutls_compression_list: ADD.
7400 gnutls_protocol_list: ADD.
7401 gnutls_certificate_type_list: ADD.
7402 gnutls_kx_list: ADD.
7403 gnutls_cipher_suite_info: ADD.
7405 * Version 1.7.7 (released 2007-02-22)
7407 ** Support for supplemental handshake messages and authorization data.
7408 Supplemental data is described in RFC 4680 and the authorization
7409 extensions in draft-housley-tls-authz-extns-07.
7411 ** Support for authorization data in gnutls-cli and gnutls-serv.
7412 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
7414 ** Fix for gnutls_x509_crt_check_hostname.
7415 Before it would have reported that the certificate matched a hostname
7416 when it did not have any dNSName or any CN field. Report and tiny
7417 patch from "Richard W.M. Jones" <rjones@redhat.com>.
7419 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
7420 Tests regressions of the bug, and several other features.
7422 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
7423 Before there were no support for iPAddress SAN's during comparison.
7425 ** New API to print information about CRL's.
7426 The function is gnutls_x509_crl_print.
7428 ** New API to extract signature value from CRL's.
7429 The function is gnutls_x509_crl_get_signature.
7431 ** Support for directoryName Subject Alternative Name's.
7432 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
7433 string in the provided buffer.
7435 ** Internal improvements to certtool.
7436 It uses gnutls_x509_crl_print to print CRL information. It uses some
7437 more gnulib modules to simplify error handling.
7439 ** API and ABI modifications:
7440 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
7441 gnutls_supplemental_data_format_type_t: ADD.
7442 gnutls_authz_data_format_type_t: ADD.
7443 gnutls_supplemental_get_name: ADD.
7444 gnutls_authz_recv_callback_func,
7445 gnutls_authz_send_callback_func: ADD, callback prototypes.
7446 gnutls_authz_enable: ADD.
7447 gnutls_authz_send_x509_attr_cert,
7448 gnutls_authz_send_saml_assertion,
7449 gnutls_authz_send_x509_attr_cert_url,
7450 gnutls_authz_send_saml_assertion_url: ADD.
7451 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
7452 gnutls_x509_crl_print: ADD.
7453 gnutls_x509_crl_get_signature: ADD.
7455 * Version 1.7.6 (released 2007-02-12)
7457 ** Support for 'otherName' Subject Alternative Names.
7458 The existing API gnutls_x509_crt_get_subject_alt_name may now return
7459 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
7460 To find out the otherName OID (necessary for proper parsing of the
7461 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
7462 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
7463 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
7464 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
7466 ** Certtool can print otherName SAN values for certificates.
7467 For known otherName OIDs (currently only id-on-xmppAddr as defined by
7468 RFC 3920), it will also print the name.
7470 ** Fix TLS 1.2 RSA signing in servers.
7471 Before it used the old-style MD5+SHA1 signature, but the TLS
7472 signatures should be normal PKCS#1 signatures. FYI, we use and
7473 require that DigestInfo parameters are present and NULL for TLS 1.2.
7475 ** Add APIs to access X.509 extensions sequentially.
7476 The existing APIs gnutls_x509_crt_get_extension_oid() and
7477 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
7478 inspect the extensions in the order defined by the certificate.
7480 ** Add API to extract signature value from X.509 certificates.
7481 The function is gnutls_x509_crt_get_signature.
7483 ** Fix crash when generating proxy certificates in batch mode.
7484 If you don't specify a proxy policy in batch mode, it will use
7487 ** Add API to print information about X.509 certificates.
7488 The function is gnutls_x509_crt_print.
7490 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
7491 One consequence of this is that the output syntax has changed
7492 slightly. Some more fields are printed.
7496 ** API and ABI modifications:
7497 gnutls_x509_crt_print: ADD
7498 gnutls_certificate_print_formats_t: ADD, new enum.
7499 gnutls_x509_crt_get_signature: ADD.
7500 gnutls_x509_crt_get_extension_data: ADD.
7501 gnutls_x509_crt_get_extension_info: ADD.
7502 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
7503 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
7504 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
7506 * Version 1.7.5 (released 2007-02-06)
7508 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
7511 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
7513 ** Fix --list output for gnutls-cli and gnutls-serv.
7514 Mention TLS1.2, SHA512 etc.
7516 ** Manual contains new section on setting up a test HTTP server.
7517 A server set up following those descriptions are available online via
7518 <http://www.gnutls.org/server.html>.
7520 ** Update of gnulib files.
7522 ** API and ABI modifications:
7523 No changes since last version.
7525 * Version 1.7.4 (released 2007-02-05)
7527 ** Support for RSA signing using SHA-256/384/512.
7528 A new self test "sha2" tries to build a long X.509 certificate chain
7529 testing all new hashes.
7531 ** The gnutls-serv tool now use static DH parameters if none are supplied.
7533 ** Discuss proxy certificates in the manual.
7535 ** Improve bibliographical citations in the manual.
7537 ** Update of gnulib files.
7539 ** Fix certtool template handling of pathLenConstraints.
7540 It now defaults to -1 instead of 0, which causes the field to be
7541 missing unless the template specify it.
7543 ** API and ABI modifications:
7546 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
7549 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
7550 GNUTLS_SIGN_RSA_SHA256,
7551 GNUTLS_SIGN_RSA_SHA384,
7552 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
7554 * Version 1.7.3 (released 2007-02-01)
7556 ** New option to certtool: --generate-proxy.
7557 This will generate a Proxy Certificate from an end entity certificate.
7558 Proxy Certificates are documented in RFC 3820. You will need to
7559 specify the proxy certificate's private key with --load-privkey, the
7560 user certificate with --load-certificate and the private key used to
7561 sign the new proxy certificate with --load-ca-privkey. Certtool will
7562 query for proxy path length and the policy language OID. Currently
7563 only OIDs that have an empty policy are supported (which includes the
7564 two OIDs defined by RFC 3820).
7566 ** Certtool --certificate-info now prints information for Proxy Certificates.
7567 Before the proxy extension was just printed as DER encoded data.
7569 ** New APIs to set proxy subject names and get/set proxy cert extension.
7571 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
7573 ** Added self-test to test for regressions of pathLenConstraint bug.
7574 Incidentally, this also test (some) other regressions or changes in
7575 the output from certtool --certificate-info.
7577 ** When certtool generates CA certificates, pressing enter on the path
7578 ** length constraint query will now remove the field.
7579 Before it set the path length constraint to 0, which is a rather poor
7582 ** Certtool now print times in UTC when printing certificate/CRL info.
7584 ** Add better fix to work around C++ compiler bug on Mac OS X.
7585 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
7587 ** Fix import of ASCII armored OpenPGP keys.
7588 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
7590 ** Update of gnulib files.
7592 ** API and ABI modifications:
7593 gnutls_x509_crt_set_proxy_dn: ADD.
7594 gnutls_x509_crt_set_proxy: ADD.
7595 gnutls_x509_crt_get_proxy: ADD.
7597 * Version 1.7.2 (released 2007-01-14)
7599 ** Certtool now print the value of the pathLenConstraints field for certs.
7601 ** Certtool now query for path length constraints when generating CA certs.
7602 For batch uses, the certtool configuration name is "path_len".
7603 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
7605 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
7606 The new functions gnutls_x509_crt_get_basic_constraints and
7607 gnutls_x509_crt_set_basic_constraints provide a superset of the
7608 functionality in the old gnutls_x509_crt_get_ca_status and
7609 gnutls_x509_crt_set_ca_status (respectively), but the old functions
7610 will continue to be supported.
7612 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
7613 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
7614 OpenCDK release with this patch will be made soon, which should bump
7615 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
7617 ** Certtool --to-p12 can now store more than one certificate in the blob.
7618 Before it could only store one certificate, but now it will read and
7619 store as many certificate there are from the --load-certificate file.
7620 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
7622 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
7623 In particular, the OpenPGP function variables are no longer part of
7624 the exported libgnutls interface, and no header files from
7625 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
7626 were never intended for non-internal purposes, and thus this does not
7627 imply a change in the external API/ABI.
7629 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
7630 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
7632 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
7633 Before these parameters were set to make GnuTLS build under mingw32,
7634 however, they appear to no longer be necessary.
7636 ** A minor fix to the C++ library to make it build.
7637 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
7639 ** Update of gnulib files.
7641 ** API and ABI modifications:
7642 gnutls_x509_crt_get_basic_constraints: ADD.
7643 gnutls_x509_crt_set_basic_constraints: ADD.
7644 cdk_pubkey_to_sexp: ADD (in opencdk).
7645 cdk_seckey_to_sexp: ADD (in opencdk).
7647 * Version 1.7.1 (released 2006-12-28)
7649 ** TLS 1.2 server side fix.
7650 The Certificate Request sent did not contain the list of supported
7651 hashes field, thus violating the protocol. It will now contain an
7652 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
7654 ** TLS 1.2 DSA signature verification fix.
7655 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
7657 ** Fix the list of trusted CAs that server's send to clients.
7658 Before, the list contained issuer DN's instead of subject DN's of the
7659 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
7661 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
7662 Also added a self-test in tests/certificate_set_x509_crl.c to test the
7663 function. Reported by Max Kellermann <max@duempel.org>.
7665 ** Encode UID fields in DN's as DirectoryString.
7666 Before GnuTLS encoded and parsed UID fields as IA5String. This was
7667 incorrect, it should have used DirectoryString. Now it will use
7668 DirectoryString for the UID field, but for backwards compatibility it
7669 will also accept IA5String UID's. Reported by Max Kellermann
7672 ** Improve out-of-sourcedir builds from CVS.
7673 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
7675 ** Bootstrap tools changed.
7676 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
7677 building GnuTLS from CVS. Libtool 1.5.22 is used.
7679 ** Fixed a syntax error in lib/gnutls.asn.
7680 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
7682 ** Added German translation of GnuTLS messages.
7684 ** Update of gnulib files.
7686 ** API and ABI modifications:
7687 No changes since last version.
7689 * Version 1.7.0 (released 2006-11-29)
7691 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
7692 The details is that the protocol priority set by
7693 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
7694 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
7696 ** Preliminary support for TLS 1.2.
7697 The client has been successfully tested against
7698 https://www.mikestoolbox.org:4433/.
7700 ** Anonself test now print a lot of debugging info, including TLS version.
7702 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
7704 ** Update of gnulib files.
7706 ** API and ABI modifications:
7707 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
7709 *** Pulled up from stable 1.6.x branch:
7711 ** Fix ./configure failure with non-GCC compilers.
7712 This fixes the following error message:
7713 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
7714 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
7716 * Version 1.6.3 (released 2007-05-26)
7718 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
7719 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
7720 from the 1.7.x branch, see
7721 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
7723 ** Have PKCS8 parser return better error codes.
7724 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
7725 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
7726 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
7728 ** Fix mem leak for sessions with client authentication via certificates.
7729 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
7730 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
7732 ** Fix building of 'tlsia' self test.
7733 Earlier some gcc are known to build tlsia linking to
7734 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
7735 the build directory, even though command line parameters look OK.
7736 Changing order of some parameters fixes it.
7738 ** API and ABI modifications:
7739 gnutls_x509_crt_get_raw_issuer_dn: ADD.
7740 gnutls_x509_crt_get_raw_dn: ADD.
7742 * Version 1.6.2 (released 2007-04-18)
7744 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
7745 Before, we remove the parameters field, which resulted in a slightly
7746 different DER encoding which in turn caused signature verification
7747 failures of GnuTLS-generated RSA certificates in some other
7748 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
7749 you read, this may or may not be correct, but our new behaviour appear
7750 to be consistent with other widely used implementations.
7752 ** Regenerate the PKIX ASN.1 syntax tree.
7753 For some reason, after changing the ASN.1 type of ldap-UID in the last
7754 release, the generated C file built from the ASN.1 schema was not
7755 refreshed. This can cause problems when reading/writing UID
7756 components inside X.500 Distinguished Names. Reported by devel
7757 <dev001@pas-world.com>.
7759 ** Updated translations.
7761 ** API and ABI modifications:
7762 No changes since last version.
7764 * Version 1.6.1 (released 2006-12-28)
7766 ** Fix the list of trusted CAs that server's send to clients.
7767 Before, the list contained issuer DN's instead of subject DN's of the
7768 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
7770 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
7771 Reported by Max Kellermann <max@duempel.org>.
7773 ** Encode UID fields in DN's as DirectoryString.
7774 Before GnuTLS encoded and parsed UID fields as IA5String. This was
7775 incorrect, it should have used DirectoryString. Now it will use
7776 DirectoryString for the UID field, but for backwards compatibility it
7777 will also accept IA5String UID's. Reported by Max Kellermann
7780 ** Fix ./configure failure with non-GCC compilers.
7781 This fixes the following error message:
7782 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
7783 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
7785 ** API and ABI modifications:
7786 No changes since last version.
7788 * Version 1.6.0 (released 2006-11-17)
7790 ** No changes since 1.5.5.
7791 The major changes compared to the 1.4.x branch are:
7793 *** A GnuTLS C++ library is part of the official distribution.
7794 Currently there are no examples or documentation, but hopefully this
7795 will change. See gnutlsxx.h for the API.
7797 *** Windows is a supported platform.
7798 There are, however, two know bugs. One is related to select() in
7799 command line tools (not, nota bene, in the library), the other is a
7800 problem with libgcrypt that causes delays. Help is needed to resolve
7801 those issues, so we feel we can't delay the release because of this.
7803 *** New APIs for custom push/pull function error reporting.
7804 The new APIs are gnutls_transport_set_errno and
7805 gnutls_transport_set_global_errno. See the release notes for version
7806 1.5.4 for more information.
7808 *** Self tests are run under valgrind, if available. See --disable-valgrind.
7810 * Version 1.5.5 (released 2006-11-16)
7812 ** Correctly bump shared library version after adding new APIs.
7813 This was forgotten in the last release.
7815 ** Fix unsigned vs signed problem in ex-x509-info.c example.
7816 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
7818 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
7820 ** Update of gnulib files.
7822 ** API and ABI modifications:
7823 No changes since last version.
7825 * Version 1.5.4 (released 2006-11-07)
7827 ** New API functions to set errno in push/pull functions.
7828 Under Windows, setting the errno variable in a push/pull replacement
7829 may end up setting the wrong errno variable, and GnuTLS send/recv
7830 functions become confused about the real errno returned from a failed
7831 push/pull function. Therefor, we have added two APIs to set the errno
7832 variable used by GnuTLS. The APIs can also help to keep things
7833 thread-safe, by avoiding potentially global variables. Typically,
7834 instead of setting errno in your push/pull function, you will call one
7835 of these functions. It is recommended to use
7836 gnutls_transport_set_errno, but if you don't have the session variable
7837 easily accessible in the push/pull replacement function, you can use
7838 gnutls_transport_set_global_errno. Suggested by Tim Kosse
7839 <tim.kosse@filezilla-project.org>.
7841 void gnutls_transport_set_errno (gnutls_session_t session, int err);
7842 void gnutls_transport_set_global_errno (int err);
7844 ** When calling `recv' or `send' Windows errors are handled properly.
7845 The Windows recv/send functions doesn't use errno, and GnuTLS now use
7846 WSAGetLastError to access the error condition instead.
7848 ** Several OpenPGP API fixes.
7849 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
7850 important fix is to change the return value of
7851 gnutls_openpgp_privkey_get_pk_algorithm and
7852 gnutls_openpgp_key_get_pk_algorithm from 'int' to
7853 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
7854 compatible with 'int').
7856 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
7857 ** version, try to negotiate the highest version support by the GnuTLS server,
7858 ** instead of the lowest.
7859 Reported by <Pasi.Eronen@nokia.com>.
7861 ** Replace old constructs with use of gnulib modules.
7862 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
7863 the code. If the headers doesn't exist on the target system, gnulib
7864 will make sure its replacement header files are used instead.
7866 ** Fix SOVERSION computation for *.def files.
7867 This fixes build errors similar to "No rule to make target
7868 `libgnutls-`expr', needed by `all-am'." when building for Windows.
7870 ** gnutls_check-version uses strverscmp from gnulib.
7872 ** Update of gnulib files.
7874 ** API and ABI modifications:
7875 gnutls_transport_set_errno: ADD
7876 gnutls_transport_set_global_errno: ADD
7878 * Version 1.5.3 (released 2006-10-26)
7880 ** Add new self-test of RSA-MD5 signature chains.
7881 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
7882 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
7883 and is based on the work by Marc Stevens et al, see
7884 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
7886 ** Re-factor self tests.
7888 ** The include copy of Libtasn1 is updated to version 0.3.7.
7890 ** The included copy of OpenCDK is updated to version 0.5.11.
7892 ** Fix the filename of the *.def file on Windows after library version bump.
7894 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
7895 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
7896 gnulib modules. Earlier we could only use the LGPL'ed module from
7897 gnulib, because two gnulib directories in the same project didn't
7900 ** API and ABI modifications:
7901 No changes since last version.
7903 * Version 1.5.2 (released 2006-10-03)
7905 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
7906 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
7907 shared library version than this version, so you'll have to remove
7908 them and possibly relink your applications. The reason for this is
7909 that no API/ABI changes have been made since the 1.4.x branch, and
7910 that incrementing the shared library version was a mistake. Reported
7911 by Andreas Metzler <ametzler@downhill.at.eu.org>.
7913 ** Fix off-by-one error when computing length to malloc.
7914 The code is used by gnutls_openpgp_add_keyring_file and
7915 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
7916 <agl@imperialviolet.org>.
7918 ** Add version script for the GnuTLS C++ library.
7919 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
7921 ** Fix the C++ compiler detection logic.
7922 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
7924 ** Update of gnulib files.
7926 ** API and ABI modifications:
7927 No changes since last version.
7929 * Version 1.5.1 (released 2006-09-21)
7931 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
7932 ** Crypto 06 rump session attack.
7933 In particular, we check that the digestAlgorithm.parameters field is
7934 missing or empty, to avoid that it can contain "garbage" that may be
7935 used to alter the numeric properties of the signature. See
7936 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
7937 not exactly the same as the problem we fix here). Reported by Yutaka
7938 OIWA <y.oiwa@aist.go.jp>.
7940 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
7941 up to date information.
7943 ** Add self test to test for above flaw.
7945 ** Fix gnutls-cli-debug regarding resume support detection.
7946 Earlier, if the session-id from the server had a length of 0, it would
7947 indicate that the server supports resumption, which isn't the case.
7948 Reported by Kataja Kai <kai.kataja@op.fi>.
7950 ** Fix building of examples on FreeBSD by including netinet/in.h.
7951 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
7953 ** Fix certtool bug that caused the private key to not be loaded when
7954 generating a certificate with --load-request, which in turn triggered
7955 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
7956 by Sascha Ziemann <sascha.ziemann@secunet.com>.
7958 ** gnutls-cli and gnutls-serv works on Windows.
7959 The problem was the select() call that doesn't work on file
7960 descriptors (stdin) on Windows. We borrowed some code from plibc to
7961 solve this. It appears to be somewhat unreliable though.
7963 ** Autoconf 2.60 is now used.
7965 ** API and ABI modifications:
7966 No changes since last version.
7968 * Version 1.5.0 (released 2006-08-13)
7970 ** Change SRP and Cert-Type extensions to match IANA registry.
7972 ** Fixed bug in OpenPGP authentication handshake.
7974 ** Improvements for building under MinGW.
7975 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
7976 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
7977 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
7978 at run-time from ws2_32.dll, and falls back on a simple replacement if
7979 it is not available. Builds the library with -mms-bitfields
7980 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
7981 create *.def files, which are installed.
7983 ** The examples now (conditionally) include config.h and link to gnulib.
7984 No other source changes were necessary, so the examples should
7985 continue to be possible to use stand-alone without any autoconf or
7988 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
7989 You may unconditionally disable it with --disable-cxx. See
7990 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
7993 ** Made command line tool '--version' behave according to GNU Standards.
7994 This enables 'make distcheck' to succeed.
7996 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
7998 ** Make --without-included-libtasn1 work.
7999 Reported by Daniel Black <dragonheart@gentoo.org>.
8001 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
8002 See https://www.gnu.org/software/gnutls/security.html regardging
8003 GNUTLS-SA-2006-2 for more up to date information. Reported by
8004 satyakumar <satyam_kkd@hyd.hellosoft.com>.
8006 ** API and ABI modifications:
8007 No changes since last version.
8009 * Version 1.4.5 (released 2006-11-06)
8011 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
8012 ** version, try to negotiate the highest version support by the GnuTLS server,
8013 ** instead of the lowest.
8014 Reported by <Pasi.Eronen@nokia.com>.
8016 ** Fix typo in doc/examples/ex-serv-pgp.c.
8017 Reported by Adam Langley" <agl@imperialviolet.org>.
8019 ** API and ABI modifications:
8020 No changes since last version.
8022 * Version 1.4.4 (released 2006-09-12)
8024 ** Relax the test that caught signatures that exploit the variant of
8025 ** Bleichenbacher's Crypto 06 rump session attack on our
8026 ** verification logic flaw.
8027 In particular, we now permit the digestAlgorithm.parameters field to
8028 be present but empty, whereas in 1.4.3 we actually checked that the
8031 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
8032 The messages are only printed in debug mode, which is not recommended
8033 for normal use, and thus logging this situation cannot be abused as an
8034 oracle in typical recommended situations.
8036 ** API and ABI modifications:
8037 No changes since last version.
8039 * Version 1.4.3 (released 2006-09-08)
8041 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
8042 ** Crypto 06 rump session attack.
8043 In particular, we check that the digestAlgorithm.parameters field is
8044 empty, to avoid that it can contain "garbage" that may be used to
8045 alter the numeric properties of the signature. See
8046 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is

8062 ** API and ABI modifications:
8063 No changes since last version.
8065 * Version 1.4.2 (released 2006-08-12)
8067 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
8068 This can happen if you call gnutls_certificate_verify_peers2 and have
8069 a certain mix of local CA certificates and the peer send special
8070 certificates, that together trigger certain behaviour. It is not
8071 known at this point whether the crash can be triggered without the
8072 special local CA certificate, and thus turn this into a remote crash
8073 of clients that verify server certificates when they talk to a server
8074 with the special server certificate. See GNUTLS-SA-2006-2 on
8075 https://www.gnu.org/software/gnutls/security.html for more up to date
8076 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
8078 ** Change SRP and Cert-Type extensions to match IANA registry.
8080 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
8082 ** Make --without-included-libtasn1 work.
8083 Reported by Daniel Black <dragonheart@gentoo.org>.
8085 ** API and ABI modifications:
8086 No changes since last version.
8088 * Version 1.4.1 (released 2006-06-14)
8090 ** Replaced inactive ifdefs to enable openpgp support in test programs.
8092 ** Fixed bug in OpenPGP authentication handshake.
8094 ** Fixed typographical in man pages.
8096 ** Build fixes of the manual.
8098 ** Added Swedish translation.
8100 ** API and ABI modifications:
8101 No changes since last version.
8103 * Version 1.4.0 (released 2006-05-15)
8105 ** Remove GnuTLS 0.8.x compatibility functions.
8107 ** The libgcrypt RNG is initialized in gnutls_global_init().
8109 ** TLS/IA API changes from Emile van Bergen.
8110 A dummy credential structure is not needed now, if you wish to use the
8111 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
8114 ** The self-tests are now run under valgrind, if it is installed.
8116 ** Libtasn1 is updated to 0.3.4, and that version is now required.
8118 ** The command line tools now use getaddrinfo and support IPv6.
8120 ** API and ABI modifications:
8121 _gnutls_x509_get_raw_crt_activation_time,
8122 _gnutls_x509_get_raw_crt_expiration_time: Removed.
8123 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
8124 gnutls_ia_enable: Added.
8126 * Version 1.3.5 (released 2006-03-08)
8128 ** Error messages are now translated using GNU Gettext.
8130 ** The function gnutls_x509_crt_to_xml now return an internal error.
8131 This means that the code to convert X.509 certificates to XML format
8132 does not work any more. The reason is that the function called
8133 libtasn1 internal functions. It seems unclean for libtasn1 to export
8134 the APIs needed here. Instead it would be better to implement XML
8135 support inside libtasn1 properly. If you need this functionality
8136 strongly, please consider looking into implementing this suggested
8137 approach instead. As a workaround, you may also modify lib/x509/xml.c
8138 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
8140 ** Libraries are now built with libtool's -no-undefined.
8141 This helps producing libraries for Windows using mingw32.
8143 ** Doc fixes to explain that gnutls_record_send can block.
8145 ** Libtasn1 0.3.1 or later is now required.
8146 The include copy has been updated too.
8148 ** gnutls-cli can now recognize services and port numbers with the -p option.
8150 ** API and ABI modifications:
8151 No changes since last version.
8153 * Version 1.3.4 (released 2006-02-09)
8155 ** Fix read of out bounds bug in DER parser.
8156 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from

8163 prevent future writes. That is to allow reading the already received data.
8164 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
8166 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
8167 gnutls_certificate_set_x509_trust(), that caused memory corruption if
8168 more than one certificates were added. Report and patch by Max Kellermann.
8170 ** Fix build problems of OpenCDK on AIX.
8171 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
8173 ** API and ABI modifications:
8174 No changes since last version.
8176 * Version 1.3.3 (released 2006-01-12)
8178 ** New API to access the TLS master secret.
8179 When possible, you should use the TLS PRF functions instead.
8180 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
8182 ** Improved handling when multiple libraries use GnuTLS at the same time.
8183 Now gnutls_global_init() can be called multiple times, and
8184 gnutls_global_deinit() will only deallocate the structure when it has
8185 been called as many times as gnutls_global_init() was called.
8187 ** Added a self test of TLS resume functionality.
8189 ** Fix crash in TLS resume code, caused by TLS/IA changes.
8191 ** Documentation fixes about thread unsafety, prompted by
8192 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
8193 In particular, gnutls_global_init() and gnutls_global_deinit() are not
8194 thread safe. Careful callers may want to protect the call using a
8195 mutex. The problem could also be ignored, which would cause a memory
8196 leak under rare conditions when two threads invoke the function
8197 roughly at the same time.
8199 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
8201 ** The code was indented again, including the external header files.
8203 ** API and ABI modifications:
8204 New functions to retrieve the master secret value:
8205 gnutls_session_get_master_secret
8207 Add a 'const' keyword to existing API:
8208 gnutls_x509_crq_get_challenge_password
8210 * Version 1.3.2 (released 2005-12-15)
8212 ** GnuTLS now support TLS Inner application (TLS/IA).
8213 This is per draft-funk-tls-inner-application-extension-01. This
8214 functionality is added to libgnutls-extra, so it is licensed under the
8215 GNU General Public License.
8217 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
8218 The PRF is used by some protocols building on TLS, such as EAP-PEAP
8219 and EAP-TTLS. One function to access the raw PRF and one to access
8220 the PRF seeded with the client/server random fields are provided.
8221 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
8223 ** New APIs to acceess the client and server random fields in a session.
8224 These fields can be useful by protocols using TLS. Note that these
8225 fields are typically used as input to the TLS PRF, and if this is your
8226 intended use, you should use the TLS PRF API that use the
8227 client/server random field directly. Suggested by Jouni Malinen
8228 <jkmaline@cc.hut.fi>.
8230 ** Internal type cleanups.
8231 The uint8, uint16, uint32 types have been replaced by uint8_t,
8232 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
8233 correct types on platforms that lack them. The uint type have been
8234 replaced by unsigned.
8236 ** API and ABI modifications:
8237 New functions to invoke the TLS Pseudo-Random-Function (PRF):
8241 New functions to retrieve the session's client and server random values:
8242 gnutls_session_get_server_random
8243 gnutls_session_get_client_random
8245 New function, to perform TLS/IA handshake:
8248 New function to decide whether to do a TLS/IA handshake:
8249 gnutls_ia_handshake_p
8251 New functions to allocate a TLS/IA credential:
8252 gnutls_ia_allocate_client_credentials
8253 gnutls_ia_free_client_credentials
8254 gnutls_ia_allocate_server_credentials
8255 gnutls_ia_free_server_credentials
8257 New functions to handle the AVP callback:
8258 gnutls_ia_set_client_avp_function
8259 gnutls_ia_set_client_avp_ptr
8260 gnutls_ia_get_client_avp_ptr
8261 gnutls_ia_set_server_avp_function
8262 gnutls_ia_set_server_avp_ptr
8263 gnutls_ia_get_server_avp_ptr
8265 New functions, to toggle TLS/IA application phases:
8266 gnutls_ia_require_inner_phase
8268 New function to mix session keys with inner secret:
8269 gnutls_ia_permute_inner_secret
8271 Low-level API (used internally by gnutls_ia_handshake):
8272 gnutls_ia_endphase_send
8276 New functions that can be used after successful TLS/IA negotiation:
8277 gnutls_ia_generate_challenge
8278 gnutls_ia_extract_inner_secret
8280 Enum type with TLS/IA modes:
8283 Enum type with TLS/IA packet types:
8286 Enum values for TLS/IA alerts:
8287 GNUTLS_A_INNER_APPLICATION_FAILURE
8288 GNUTLS_A_INNER_APPLICATION_VERIFICATION
8290 New error codes, to signal when an application phase has finished:
8291 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
8292 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
8294 New error code to signal TLS/IA verify failure:
8295 GNUTLS_E_IA_VERIFY_FAILED
8297 * Version 1.3.1 (released 2005-12-08)
8299 ** Support for DHE-PSK cipher suites has been added.
8300 This method offers perfect forward secrecy.
8302 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
8303 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
8305 ** Corrected a bug in certtool for 64 bit machines. Reported
8306 by Max Kellermann <max@duempel.org>.
8308 ** New function to set a X.509 private key and certificate pairs, and/or
8309 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
8310 <emile@e-advies.nl>.
8312 The integrity of the PKCS#12 file is protected through a password
8313 based MAC; public-key based signatures for integrity protection are
8314 not supported. PKCS#12 bags may be encrypted using password derived
8315 symmetric keys, public-key based encryption is not supported. The
8316 PKCS#8 keys may be encrypted using passwords. The API use the same
8317 password for all operations. We believe that any more flexibility
8318 create too much complexity that would hurt overall security, but may
8319 add more PKCS#12 related APIs if real-world experience indicate
8322 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
8323 reported by Emile van Bergen <emile@e-advies.nl>.
8324 This will enable "certtool -k -8" to parse those keys.
8326 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
8327 Use "certtool -p -8" and press press enter at the prompt. Earlier,
8328 certtool would have encrypted the key using an empty password.
8330 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
8331 Earlier it would have prompted the user for it, even if --password was
8334 ** Added self test of PKCS#8 parsing.
8335 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
8336 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
8339 ** API and ABI modifications:
8340 New function to set X.509 credentials from a PKCS#12 file:
8341 gnutls_certificate_set_x509_simple_pkcs12_file
8343 New gnutls_kx_algorithm_t enum type:
8346 New API to return session data (basically same as gnutls_session_get_data):
8347 gnutls_session_get_data2
8349 New API to set PSK Diffie-Hellman parameters:
8350 gnutls_psk_set_server_dh_params
8352 * Version 1.3.0 (2005-11-15)
8354 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
8355 This add several new APIs, see below. Read the updated manual for
8356 more information. A new self test "pskself" has been added, that will
8357 test this functionality.
8359 ** The session resumption data are now system independent.
8361 ** The code has been re-indented to conform to the GNU coding style.
8363 ** Removed the RIPEMD ciphersuites.
8365 ** Added a discussion of the internals of gnutls in manual.
8367 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
8369 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
8371 ** Make sure config.h is included first in a few files, from Albert Chin.
8373 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
8375 ** Don't install SRP programs and man pages if --disable-srp-authentication,
8378 ** API and ABI modifications:
8379 New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
8381 New gnutls_credentials_type_t credential type:
8384 New credential types:
8385 gnutls_psk_server_credentials_t
8386 gnutls_psk_client_credentials_t
8388 New functions to allocate PSK credentials:
8389 gnutls_psk_allocate_client_credentials
8390 gnutls_psk_free_client_credentials
8391 gnutls_psk_free_server_credentials
8392 gnutls_psk_allocate_server_credentials
8394 New enum type for PSK key flags:
8395 gnutls_psk_key_flags
8397 New function prototypes for credential callback:
8398 gnutls_psk_client_credentials_function
8399 gnutls_psk_server_credentials_function
8401 New function to set PSK username and key:
8402 gnutls_psk_set_client_credentials
8404 New function to set PSK passwd file:
8405 gnutls_psk_set_server_credentials_file
8407 New function to extract PSK user in server:
8408 gnutls_psk_server_get_username
8410 New functions to set PSK callback:
8411 gnutls_psk_set_server_credentials_function
8412 gnutls_psk_set_client_credentials_function
8414 Use size_t instead of int for output size parameter:
8415 gnutls_srp_base64_encode
8416 gnutls_srp_base64_decode
8418 * Version 1.2.11 (2006-05-11)
8419 - The function gnutls_x509_crt_to_xml is not supported any more, and
8420 return an internal error. The reason is that the function called
8421 internal libtasn1 functions which are no longer exported from
8423 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
8424 - Updated gnulib compatibility files.
8425 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
8426 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
8427 - API and ABI modifications:
8428 No changes since last version.
8430 * Version 1.2.10 (2006-02-09)
8431 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
8432 <admin@gleg.net>, and debugging help from Protover SSL.
8433 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
8434 The included version has been updated too.
8435 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
8436 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
8437 - Corrected a bug in certtool for 64 bit machines. Reported
8438 by Max Kellermann <max@duempel.org>.
8439 - Corrected bugs in gnutls_certificate_set_x509_crl() and
8440 gnutls_certificate_set_x509_trust(), that caused memory corruption if
8441 more than one certificates were added. Report and patch by Max Kellermann.
8442 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
8443 longer invalidate a session if the underlying send fails, but it will
8444 prevent future writes. That is to allow reading the already received data.
8445 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
8447 * Version 1.2.9 (2005-11-07)
8448 - Documentation was updated and improved.
8449 - RSA-MD2 is now supported for verifying digital signatures.
8450 - Due to cryptographic advances, verifying untrusted X.509
8451 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
8452 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
8453 applications that must remain interoperable, you can use the
8454 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
8455 flags when verifying certificates. Naturally, this is not
8456 recommended default behaviour for applications. To enable the
8457 broken algorithms, call gnutls_certificate_set_verify_flags with the
8458 proper flag, to change the verification mode used by
8459 gnutls_certificate_verify_peers2.
8460 - Make it possible to send empty data through gnutls_record_send,
8461 to align with the send(2) API.
8462 - Some changes in the certificate receiving part of handshake to prevent
8463 some possible errors with non-blocking servers.
8464 - Added numeric version symbols to permit simple CPP-based feature
8465 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
8466 - The (experimental) low-level crypto alternative to libgcrypt used
8467 earlier (Nettle) has been replaced with crypto code from gnulib.
8468 This leads to easier re-use of these components in other projects,
8469 leading to more review and simpler maintenance. The new configure
8470 parameter --with-builtin-crypto replace the old --with-nettle, and
8471 must be used if you wish to enable this functionality. See README
8472 under "Experimental" for more information. Internally, GnuTLS has
8473 been updated to use the new "Generic Crypto" API in gl/gc.h. The
8474 API is similar to the old crypto/gc.h, because the gnulib code were
8475 based on GnuTLS's gc.h.
8476 - Fix compiler warning in the "anonself" self test.
8477 - API and ABI modifications:
8478 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
8479 This doesn't reflect a change in behaviour,
8480 so we don't break backwards compatibility.
8481 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
8482 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
8483 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
8484 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
8486 gnutls_x509_crt_list_verify,
8487 gnutls_x509_crt_verify, or
8488 gnutls_certificate_set_verify_flags.
8489 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
8490 used when broken signature algorithms
8491 is used (currently RSA-MD2/MD5).
8492 LIBGNUTLS_VERSION_MAJOR,
8493 LIBGNUTLS_VERSION_MINOR,
8494 LIBGNUTLS_VERSION_PATCH,
8495 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
8496 version number, can be used for feature existence
8499 * Version 1.2.8 (2005-10-07)
8500 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
8501 - Don't install the auxilliary libexamples library used by the
8502 examples in doc/examples/ on "make install", report and tiny patch
8503 from Thomas Klausner <tk@giga.or.at>.
8504 - If you pass a X.509 CA or PGP trust database to the command line
8505 tool, it will now abort the connection if the server certificate
8506 validation fails. Use the parameter --insecure to continue even
8507 after certificate validation failures. Inspired from discussion
8508 with Alexander Kotelnikov <sacha@myxomop.com>.
8509 - The test for socklen_t has been moved to gnulib.
8510 - Link failures for duplicate or missing "program_name" symbol has been fixed,
8511 patch from Martin Lambers <marlam@marlam.de>.

8516 Anton Altaparmakov <aia21@cam.ac.uk>.
8517 - The GTK-DOC manual should build with current released tools.
8518 (But a copy of the output is included, so the tools are not required.)
8519 - The inet_ntop function is now used through gnulib.
8520 - API and ABI modifications:
8521 No changes since last version.
8523 * Version 1.2.7 (2005-09-09)
8524 - The GnuTLS and GnuTLS-extra libraries are now built with versioned symbols.
8525 - Certtool now complains when reading out-of-range X.509 serial
8526 numbers, suggested by Fran <e_agf@yahoo.es>.
8527 - Certtool now uses the readline library (when available) when reading
8528 X.509 serial numbers.
8529 - Fixed build problems in getpass on uClibc and Mingw32 platforms.
8530 - Fixed compile warning regarding socklen_t on Mingw32, reported by
8531 Martin Lambers <marlam@marlam.de>.
8532 - Fixed examples in doc/examples/, suggested by Fran <e_agf@yahoo.es>.
8533 - Gnulib is now used for the core library, enabling future code cleanups.
8534 - The gnutls-cli tool now use gnutls_certificate_verify_peers2,
8535 suggested by Daniel Stenberg <daniel@haxx.se>.
8536 - Doc fixes for gnutls_transport_set_push and gnutls_transport_set_pull.

8546 fixed, reported by Matthias Urlichs <smurf@smurf.noris.de>.
8547 - Will now test for liblzo functionality in liblzo2 too, reported by
8548 Thomas Klausner <tk@giga.or.at>.
8549 - Minilibtasn1 is now 0.2.14 (no code changes).
8550 - Some code changes to avoid GTK-DOC warnings.
8551 - API and ABI modifications:
8552 No changes since last version.
8554 * Version 1.2.5 (2005-07-03)
8555 - More builddir != srcdir fixes, reported by Mike Castle
8556 <dalgoda@ix.netcom.com>.
8557 - Fixed off-by-one bug in the size parameter of gnutls_x509_crt_get*_dn,
8558 reported by Adam Langley <alangley@gmail.com>.
8559 - Corrected some stuff in minilzo detection. Pointed out by
8561 - MiniLZO updated to version 2.00.
8562 - gnutls_x509_crt_list_import now accept a DER formatted CRL.
8563 - API and ABI modifications:
8564 No changes since last version.
8566 * Version 1.2.4 (2005-05-28)
8567 - Corrected some bugs that could affect 64 bit systems.
8568 - Some corrections in the header files to include the prototype
8569 of memmem properly (affected 64 bit systems). Report and patch
8570 by Yoann Vandoorselaere <yoann@prelude-ids.org>.
8571 - Introduced the --fix-key option to certtool, which can be used to
8572 regenerate the (optional) parameters in a private key. It should
8573 be used together with --key-info.
8574 - Corrected a bug in certificate chain verification that could lead
8575 to marking a trusted chain as non trusted, if the last certificate in
8576 the chain was a self signed one.
8577 - Gnulib portability files were updated.
8578 - License were updated to reflect new FSF address.
8579 - API and ABI modifications:
8580 No changes since last version.
8582 * Version 1.2.3 (2005-04-28)
8583 - Corrected bug in record packet parsing that could lead
8584 to a denial of service attack.
8585 - Corrected bug in RSA key export. Previously exported keys
8586 can be fixed using certtool. Use certtool -k <infile >outfile
8587 - API and ABI modifications:
8588 gnutls_x509_privkey_fix(): Add.
8590 * Version 1.2.2 (2005-04-25)
8591 - gnutls_error_to_alert() now considers
8592 GNUTLS_E_UNEXPECTED_HANDSHAKE_PACKET.
8593 - Fixed error in session resuming that could cause a crash in a session.
8594 - Fixed pkcs12 friendly name and local key identifier decoding.
8595 - Internal cleanups, removed duplicate typedef/struct definitions,
8596 and made source code include external include file, to check
8597 function prototypes during compile time.
8598 - API and ABI modifications:
8599 No changes since last version. At least not intentional, but due
8600 to the include header changes, there may be inadvertant changes,
8601 please let us know if you find any.
8603 * Version 1.2.1 (2005-04-04)
8604 - gnutls_bye() will no longer fail when RDWR is used and application
8605 data are available for reading.
8606 - Added more strict checks for the SRP parameters (g,n), when they
8607 are not in the included list.
8608 - Added warning to certtool when MD5 is being used for digital
8610 - Optimizations ("-O2 -finline-functions") are not enabled by default,
8611 instead the standard autoconf defaults are used. Use `./configure
8612 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
8613 - Added the option --get-dh-params to certtool, in order to get the
8614 parameters included in the library primes and generators.
8615 - Improved the semantics of GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT, to
8616 allow only trusted Version 1 CAs and introduced
8617 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT which has the old semantics.
8618 - Nettle self tests now build properly, reported by Pierre
8619 <pierre42d@9online.fr>.
8620 - Eliminated some memory leaks in DHE and RSA-EXPORT cipher suites.
8621 Reported by Yoann Vandoorselaere <yoann@prelude-ids.org>.
8622 - If the library has been compiled with features disabled, a warning is
8623 issued during the compilation of any program.
8624 - API and ABI modifications:
8625 gnutls_x509_crt_list_import(): Add
8626 gnutls_x509_crq_get_attribute_by_oid(): Add.
