        * tools/nettle-hash.c (find_algorithm): Deleted function.
        (main): Replaced by call to nettle_lookup_hash.

        * testsuite/meta-hash-test.c (test_main): Use nettle_lookup_hash.

        * nettle-meta.h (nettle_hashes): New macro, expanding to a call to
        nettle_get_hashes. Direct access to the array causes the array
        size to leak into the ABI, since a plain un-relocatable executable
        linking with libnettle.so gets copy relocations for any referenced
        data items in the shared library.

        * nettle-meta-hashes.c (nettle_get_hashes): New function.

2017-10-16  Niels Möller  <nisse@lysator.liu.se>

        function.
        (decode_base64): Use it.

        * sexp-transport-format.c (base64_encode_in_place): New helper
        function.

        (base64_encode_final): Change type of destination to char *.
        * base16-encode.c (base16_encode_single, base16_encode_update):
        Likewise.

2017-09-12  Niels Möller  <nisse@lysator.liu.se>

        * testsuite/testutils.h (mpn_zero_p): Avoid redefining mpn_zero_p
        when building with mini-gmp. Since the mini-gmp update, this
        function is defined by mini-gmp, causing link errors if nettle is
        configured with --enable-mini-gmp --disable-shared. Reported by
        Tim Rühsen.

2017-09-09  Daiki Ueno  <dueno@redhat.com>

        * testsuite/ecc-mul-g-test.c (test_main): Fixed mpn_cmp call.
        * testsuite/ecc-mul-a-test.c (test_main): Likewise.
        * eccdata.c (ecc_point_out): Write to given stream, instead of
        stderr.
        * eccdata.c (output_curve): In curve448, the bit size of the order
        is slightly smaller than the one of p's. Adjust ecc_Bmodq_shifted
        accordingly.

2017-09-09  Niels Möller  <nisse@lysator.liu.se>

        * mini-gmp.c: Updated mini-gmp from the gmp repository, latest
        change from 2017-07-23.
        * mini-gmp.h: Likewise.

2017-09-06  Niels Möller  <nisse@lysator.liu.se>

        * hkdf.c (hkdf_expand): Eliminate a (signed) ssize_t variable, use
        break rather than return at loop termination.

        (NUMB_BITS): ...new name
        * config.make.in: Update corresponding substitution.

2017-08-26  Niels Möller  <nisse@lysator.liu.se>

        * examples/nettle-openssl.c (struct openssl_cipher_ctx): New
        struct. Use everywhere, instead of typing EVP_CIPHER_CTX pointers
        directly.

        * configure.ac: Update openssl-related tests. Checks for
        cipher-specific headers are replaced by a check for openssl/evp.h,
        and the check for the BF_ecb_encrypt function is replaced by a
        check for EVP_CIPHER_CTX_new.

2017-08-03  Daniel P. Berrange  <berrange@redhat.com>

        * examples/nettle-openssl.c: Rewritten to use openssl's EVP APIs.
        The older cipher-specific functions always use openssl's generic
        software implementation, while the EVP functions enables
        platform-specific code, e.g., using the x86 AES-NI instructions.
        (nettle_openssl_init): New function.

2017-07-18  Niels Möller  <nisse@lysator.liu.se>

        * ecc-add-eh.c (ecc_add_eh): Fix in-place operation by reordering

        invalid call to mpn_mul with overlapping operands. Reported by
        Sergei Trofimovich.

2017-06-09  Niels Möller  <nisse@lysator.liu.se>

        * pss.c (pss_verify_mgf1): Check for m being too large, fixing an
        assertion failure for certain invalid signatures. Based on a patch
        contributed by Daiki Ueno.

        * testsuite/rsa-pss-sign-tr-test.c (test_main): Add test case
        contributed by Daiki Ueno. Problem originally found by oss-fuzz,
        see https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2132.
        That problem report is currently embargoed, but will hopefully be
        public in a month or two.

2017-05-23  Niels Möller  <nisse@lysator.liu.se>

        Rework the previous change, which had the unintended effect of
        always regenerating .test-rules.make after ./configure is run.
        * testsuite/Makefile.in (test-rules.stamp): New stamp file target,
        depend on Makefile.in, and run $(MAKE) test-rules.
        (.test-rules.make): Add a level of indirection, by depending on

        * testsuite/Makefile.in: Ensure .test-rules.make is regenerated
        when Makefile.in is modified.

2017-04-09  Niels Möller  <nisse@lysator.liu.se>

        * testsuite/dlopen-test.c (main): Call dlclose, to fix memory leak

        pss_encode_mgf1 is side-channel silent with respect to the salt
        and digest inputs. It turns out that the most significant bits of
        the padded bignum, and hence its size, depends on these inputs.
        Which results in a data-dependent branch in the normalization code
        of at the end of gmp's mpz_import.

2017-04-04  Niels Möller  <nisse@lysator.liu.se>

        * pss.c (pss_verify_mgf1): Use const for input mpz_t argument.

2016-03-15  Niels Möller  <nisse@lysator.liu.se>

        * twofish.c (gf_multiply): Change return value to uint32_t, to
        make shifting of the return value well defined, without any type
        casts. Fixes an undefined shift in compute_s, reported by Nikos
        Mavrogiannopoulos.
        (h_byte): Deleted type casts.

        * blowfish.c (blowfish_encrypt, blowfish_decrypt): Use READ_UINT32
        macro. Fixes an undefined shift, reported by Nikos

        counter, making the function clear some bytes beyond the end of
        the output buffer. The bug triggered a make check failure on ARM.

        * testsuite/testutils.c (ecc_curves): Include curve25519 in list.
        (test_ecc_mul_a): Include reference points for curve25519 (with
        Edwards coordinates). Allow n == 0 and n == 1, comparing to zero

        curve.

        * ecc-mul-a-eh.c (ecc_mul_a_eh, table_init): Take an Edwards point
        as input, not a Montgomery point. Hence, use ecc_a_to_j, not
        ecc_a_to_eh.

        * ecc-eh-to-a.c (ecc_eh_to_a): Just convert to affine coordinates,
        don't transform from Edwards to Montgomery form. Also reduces

        * ecdsa-keygen.c (ecdsa_generate_keypair): Use struct ecc_curve
        function pointers.

        * testsuite/curve25519-dup-test.c: Deleted file. In the way for
        conversion to Edwards coordinate convention, and in the end
        the tests will be done by ecc-dup-test.c.

        * testsuite/Makefile.in (TS_HOGWEED_SOURCES): Removed

        * curve25519-mul.c (curve25519_mul): Switch to use Montgomery
        ladder. About 20% faster than current Edwards curve operations.
        Difference is expected to shrink when Edwards operations are
        optimized to take advantage of the twist, but it seems unlikely to
        get significantly faster than the Montgomery ladder.

        * gmp-glue.c (cnd_swap): Moved function here, made non-static.
        Changed cnd type to mp_limb_t, for consistency with GMP

        rule for transforming .asm to .o, and drop include of asm.d.
        Possible now since we generate a single object file from each asm
        file. This change also helps Solaris' make recognize .asm files.

        * configure.ac: Delete code to generate asm.d.

        * Makefile.in: Delete all uses of *.po files, use the same object

        variables. Instead, use CCPIC directly when compiling all library
        files.
        (CCPIC): Set to empty, if --disable-pic is used.

        * config.make.in (SHLIBCFLAGS, CCPIC_MAYBE): Deleted.
        (COMPILE, COMPILE_CXX): Drop CCPIC. New variable EXTRA_CFLAGS,
        which can be set by individual Makefiles.

        Also delete all uses of CCPIC_MAYBE and SHLIBCFLAGS.

        * curve25519-eh-to-x.c (curve25519_eh_to_x): New file, new
        function. The curve25519 transform currently done by ecc_eh_to_a,
        but which should eventually be eliminted from that function.
        * Makefile.in (hogweed_SOURCES): Added curve25519-eh-to-x.c.
        * ecc-internal.h (curve25519_eh_to_x): Declare it.

        * curve25519-mul.c (curve25519_mul): Use it.

        (bench_curve): Use bench_add_hhh for all curves. Use ecc->mul_itch
        for scratch size.

        Switch the curve25519 implementation to use the isomorphism to the
        twisted Edwards curve which is used for Ed25519 signatures.
        * eccdata.c (ecc_curve_init): Tweaked the transformation constant
        for the isomorphism between curve25519 and the twisted Edwards
        curve.
        * ecc-add-ehh.c (ecc_add_ehh): Updated formulas for the twist curve.

        add_hhh_itch. Updated all instances.

        function, not the corresponding macro.
        * ecc-ecdsa-verify.c (ecc_ecdsa_verify_itch): Take ecc->mul_itch
        into account. Also reduce to 5*ecc->size + ecc->mul_itch.

        obscure case of ecdsa using curve25519.
        * testsuite/ecdsa-verify-test.c (test_main): Likewise (depends on
        above changes).

        * ecc-ecdsa-sign.c (ecc_ecdsa_sign): Use mul_g and h_to_a function
        pointers. Implies (obscure) support for curve25519.

        * ecc-j-to-a.c (ecc_j_to_a): For curves using redc, always convert
        back from redc form. When producing x coordinate only, optionally

        initial version yields 30% speedup of ecc_25519_modp. Early

        * testsuite/Makefile.in (clean): Delete sha1-huge-test.

        * Makefile.in (install-info, install-headers): Don't use $< and

        * testsuite/Makefile.in: Use %-rules for building the -test
        executables, in addition to the suffix rules. Hopefully, this
        should make all of GNU make, BSD make and Solaris make happy.
        Use $(EXEEXT) and $(OBJEXT) more consistently.

        * examples/Makefile.in: Use explicit rules for all executable
        targets. Use $(EXEEXT) and $(OBJEXT) more consistently.

        sparc/arcfour-crypt.asm.

        * examples/nettle-benchmark.c (display): Use two decimal places.

        * sparc/arcfour-crypt.asm: Reorganized. Main loop unrolled four
        times. Uses aligned 32-bit write accesses at DST. Still uses 8-bit
        read accesses at SRC; could be improved int he case that SRC and
        DST have compatible alignment.

2005-10-19  Niels Möller  <niels@s3.kth.se>

        have compatible alignment. Improves performance by 20%, but I'm
        not sure it's worth the extra complexity.

        * bignum.c (nettle_mpz_from_octets): Removed sign argument. If
        mpz_import is available, define nettle_mpz_from_octets as a macro
        calling mpz_import.
        (nettle_mpz_from_octets): Start by setting x to zero; callers no
        longer need to do that.
        (nettle_mpz_set_str_256_s): New logic for the handling of negative
        numbers. Convert in the same way as for positive numbers, and then
        subtract the appropriate power of two.

2005-10-17  Niels Möller  <nisse@lysator.liu.se>

        * bignum.c (nettle_mpz_from_octets): Improved loop. Removed the

        sparc32.
        (BIAS): Define magic stack bias constant.

        * sparc/aes-encrypt-internal.asm, sparc/aes-decrypt-internal.asm:
        Reduced frame size to 104 bytes, since we no longer need wtxt and
        tmp on the stack.

        * sparc/aes.asm: Deleted old aes implementation.

        * sparc/aes-decrypt-internal.asm: New file.

        * sparc/machine.m4: Don't use m4 eval, instead rely on the
        assembler's arithmetic.

        * sparc/machine.m4 (AES_FINAL_ROUND): Better scheduling, by
        interleaving independent operations.

        * sparc/machine.m4 (TMP3): A third temporary register.

        avoid the additions of the AES_TABLEx constants in the inner loop.

        * sparc/machine.m4 (AES_ROUND): Better scheduling, by
        interleaving independent operations.

        * sparc/machine.m4 (AES_ROUND): Alternate between using TMP1 and

        NOPs in the load dely slots.

        * sparc/aes-encrypt-internal.asm: Implemented. Not yet working,
        and not optimized.

        * sparc/machine.m4: Use TMP1 and TMP2, so we don't need to pass
        them as arguments.
        (AES_FINAL_ROUND): New macro.

2005-10-15  Niels Möller  <nisse@lysator.liu.se>

        Also take more of the used registers as argument.

        * x86/aes-encrypt-internal.asm: Rewritten to match new interface,
        with the table pointer as an argument. Unlike the old code, this
        should really be position independent.

        * configure.ac: When looking for assembler files, link in
        aes-encrypt-internal.asm and aes-decrypt-internal.asm. Don't look

        * x86/sha1-compress.asm (EXPAND): Use % 16 instead of & 15 to
        compute offsets mod 16, since m4 on FreeBSD 49.RELEASE and NetBSD
        doesn't implement & correctly in eval.

        argument is now a pointer to the input data in unaligned,
        big-endian form.

        moved to noinst_HEADERS.
        (SHLIBOBJECTS): Substitute from libnettle_a_SOURCES, not
        am_libnettle_a_OBJECTS, since the latter includes
        libnettle_a-prefixes with some automake versions.
        (SHLIBSONAME): Check if this name is empty, which is the case on
        cygwin, before using it.

2004-08-31  Niels Möller  <nisse@lysator.liu.se>

        * configure.ac: New command line option --disable-pic. Use

        * des-compat.h (const_des_cblock): New bogus type. Disabled use of
        const, for compatibility with openssl.

        Windows_NT (and Windows_95 and Windows_98) running on "x86" and
        "686".

2004-02-26  Niels Möller  <nisse@lysator.liu.se>

        * nettle-meta.h (nettle_crypt_func): Typedef moved to cbc.h.
        Include cbc.h instead.

        * des-compat.c: Reverted const change, now all the des_key_sched
        arguments are not const. This is also what openssl's interface
        looks like.
        (cbc_crypt_func): Deleted typedef, use nettle_crypt_func instead.

        * cbc.h (nettle_crypt_func): Moved typedef here.
        * cbc.c (cbc_encrypt, cbc_decrypt_internal, cbc_decrypt): Use it
        for typing the f argument. Reverted the const change, for
        compatibility with nettle_crypt_func.

2004-02-25  Niels Möller  <nisse@lysator.liu.se>

        * testsuite/des-compat-test.c: Use des_cblock for typing more of
        the variables. Use const. Got rid of most of the explicit casts.

        parity.

        * testsuite/des-compat-test.c (C_Block, Key_schedule): Deleted
        defines. Deleted some of the explicit casts.

        * Makefile.am: Protected %-rules used for building pure objects,
        and for assembler files, by automake conditionals. Needed for
        makes such as tru64's, which tries to understand %-patterns, but
        doesn't get it right.
        (SUFFIXES): Added .html.
        (.texinfo.html): Rewrote rule to use a traditional suffix target.

        * configure.ac (enable_assembler): Explicitly set

        files.
        (ENABLE_ASSEMBLER, ENABLE_SHARED): New automake conditionals.

        * testsuite/testutils.c (xalloc): xalloc(0) should work also on
        systems where malloc(0) returns NULL.

2004-02-16  Niels Möller  <niels@s3.kth.se>

        * Makefile.am (%.o: %.asm): Added comment about OSF1 make problem.

2004-02-15  Niels Möller  <nisse@lysator.liu.se>

        * testsuite/testutils.h: #include nettle-types.h instead of

        rsa-encrypt. Needed for the test to work on systems with no
        /dev/urandom.

2004-02-12  Niels Möller  <niels@s3.kth.se>

        * configure.ac (CPPFLAGS, LDFLAGS): No spaces after -I and -L, as
        some C compilers, in particular True64 cc, don't like that.

2004-02-08  Niels Möller  <nisse@lysator.liu.se>

        * configure.ac: Bumped version number to 1.10.

2004-02-07  Niels Möller  <nisse@lysator.liu.se>

        * Released nettle-1.9.

        * testsuite/pkcs1-test.c: Include pkcs1.h only if WITH_PUBLIC_KEY.

        * pgp-encode.c [!HAVE_LIBGMP]: Kludge around the pgp.h's
        dependency on gmp.h.
        (pgp_put_mpi): Condition on HAVE_LIBGMP.

        * pgp.h: Don't include bignum.h, to make it possible to compile
        the non-bignum parts of pgp-encode.c without bignum support. Needs
        to be fixed properly before the pgp interface is advertised.

        * tools/sexp-conv.c (xalloc): New function.
        (main): Use xalloc.

        * tools/output.c (sexp_put_digest): Use TMP_DECL instead of alloca.

        * examples/nettle-openssl.c: When calling des_key_sched and
        des_ecb_encrypt, cst arguments to (void *). Openssl's typedefs
        des_cblock and const_des_cblock are too broken.

        * examples/nettle-benchmark.c (xalloc): New function. Use instead
        of alloca, for better portability.

        * examples/io.c (xalloc): New function.

        * Makefile.am (nodist_libnettleinclude_HEADERS): nettle-types.h
        should not be distributed.

2004-02-06  Niels Möller  <niels@s3.kth.se>

        * x86/sha1-compress.asm: Rename round -> ROUND.

        * x86/sha1-compress.asm: Store the magic constants on stack.
        Accessing them via %esp should be a little faster than using large
        immediate operands.

        * Makefile.am (EXTRA_DIST, DISTCLEANFILES): Handle
        sha1-compress.asm.

        * configure.ac: Use assembler file sha1-compress.asm if available.

2004-02-05  Niels Möller  <nisse@lysator.liu.se>

        * examples/rsa-encrypt.c (process_file): Copy the leftover to the
        start of the buffer, when preparing for the final processing.

        * examples/nettle-benchmark.c (bench_hash, time_hash): New functions.
        (main): Benchmark hash functions too.
        (BENCH_BLOCK): Increased 10K.
        (BENCH_INTERVAL): Decreased to 0.25s.

        * examples/nettle-benchmark.c (time_function): Loop around calling
        f, until 1s has elapsed. Returns seconds per call. Updated bench
        functions to not loop themselves.
        (display): Updated MB/s calculation.

        * testsuite/arcfour-test.c (test_main): Use test_cipher_stream.

        * testsuite/testutils.c (test_cipher_stream): New function, that
        tries dividing the input into varying size blocks before
        processing.

        * x86/arcfour-crypt.asm (nettle_arcfour_crypt): Bug fix, half of
        the S array swap was forgotten.
        * arcfour.c (arcfour_stream): Likewise.
        * arcfour-crypt.c (arcfour_crypt): Likewise.

2004-02-05  Niels Möller  <niels@s3.kth.se>

        distributed.
        (DISTCLEANFILES): And that the symlinks and .s files are deleted.

        * x86/aes-encrypt.asm, x86/aes-decrypt.asm, x86/arcfour-crypt.asm:
        Fixed debug information.

        * x86/arcfour-crypt.asm: New file. About three times faster than
        the optimized C code.

        * configure.ac: Use assembler file arcfour-crypt.asm if available.

        * arcfour.c (arcfour_crypt): Moved function too...
        * arcfour-crypt.c (arcfour_crypt): New file.

        * arcfour.c (arcfour_crypt): Optimization suggested by Jonas
        Walldén. Makes arcfour up to 50% faster on x86 and ppc, and
        probably on other architectures as well.

2004-01-31  Niels Möller  <nisse@lysator.liu.se>

        * configure.ac (AX_CREATE_STDINT_H): Also look for uint32_t and

        * rsa-keygen.c (bignum_next_prime): Fixed off-by-one error when
        comparing input to the largest listed prime. General cleanup, as
        prime_limit > 0 always. Use TMP_DECL and TMP_ALLOC.

        * nettle-internal.h (TMP_DECL, TMP_ALLOC): New macros. When alloca
        is unavailable, they work by allocating a fix amount of stack and
        imposing a hard limit on what can be allocated. Updated all users
        of alloca.

2004-01-07  Niels Möller  <nisse@harpo.hack.org>

        * nettle-types.h: New (generated) file, to be used instead of

        nettle-types.h.

        * configure.ac (AX_CREATE_STDINT_H): Create nettle-types.h.

        new function hex2int. Also implemented calculation of total
        storage, removed the dependence on the .comment section, and use
        the $FILTER environment variable as a regexp for restricting the
        object files that are considered.

2003-09-21  Niels Möller  <nisse@cuckoo.hack.org>

        * testsuite/rsa-encrypt-test.c (test_main): Don't use gmp_printf,
        as it seems it's only available with the newer gmp. Use
        mpz_out_str instead.

2003-09-19  Niels Möller  <niels@s3.kth.se>

        * examples/Makefile.am (EXTRA_DIST): Added rsa-session.h.

        rsa-decrypt.

        * examples/io.c (write_file): New function.
        (write_string): Simplified error check, it's no real point in
        calling ferror unless we also call fflush.

        * examples/rsa-keygen.c (main): Check return value from
        simple_random.

        * examples/rsa-decrypt.c, examples/rsa-encrypt.c,
        examples/rsa-session.h: New files, demonstrating rsa encryption
        and decryption.

        * configure.ac (RSA_EXAMPLES): Added rsa-encrypt and rsa-decrypt.

2003-09-01  Niels Möller  <nisse@cuckoo.hack.org>

        * testsuite/hmac-test.c (test_main): Added tests for hmac-sha256,
        from draft-ietf-ipsec-ciph-sha-256-01.txt.

        * hmac-sha256.c (hmac_sha256_digest): New file.

        * sha-example.c (display_hex): Simplified by using printf better.

        * nettle.texinfo (Example): Use @verbatiminclude to include the
        example program.

        Fixed bugs reported by Mark Arking.

2003-04-14  Niels Möller  <niels@s3.kth.se>

        * testsuite/Makefile.am (TS_SH): New test case symbols-test.
        (EXTRA_PROGRAMS): Added testutils, as a kludge to
        get automake to track dependencies for testutils.o.

        redefining.

        * New name mangling, to reduce the risk of link collisions. All
        functions (except memxor) now use a nettle_ or _nettle prefix when
        seen by the linker. For most functions, the header file that
        declares a function also use #define to provide a shorter more
        readable name without the prefix.

2003-03-11  Niels Möller  <nisse@cuckoo.hack.org>

2003-02-10  Niels Möller  <nisse@cuckoo.hack.org>

        * testsuite/sexp-format-test.c (test_main): New test with tokens
        in the format string.
        (test_main): Test space-searated literals too.

        * rsa2sexp.c (rsa_keypair_to_sexp): New argument ALGORITHM_NAME.
        * examples/rsa-keygen.c (main): Updated call to rsa_keypair_to_sexp.
        * testsuite/rsa2sexp-test.c (test_main): Likewise.

        * sexp-format.c (sexp_vformat): Allow whitespace in format string.

        The testfunctions use these instead of using echo directly.
        Use the test input '3:"\x' instead of '2:"\', to be friendlier to
        sysv echo.

2003-02-05  Niels Möller  <nisse@lysator.liu.se>

        * des-compat.h (des_set_key): Different name mangling, if this

        behaves like openssl's.

        * des-compat.c (des_key_sched, des_is_weak_key): Use the name
        nettle_des_set_key for referring to Nettle's function.

        * des.h (des_set_key): Name mangling, linker symbols should use a
        "nettle_" prefix, and this one collided with openssl. Perhaps all
        symbols should be mangled in a similar way, but that's for later.

        * configure.ac (LDFLAGS): --with-lib-path should add to LDFLAGS,
        not replace it.

2003-01-30  Niels Möller  <nisse@cuckoo.hack.org>

        -lcrypto to OPENSSL_LIBFLAGS, not the plain LDFLAGS.

2003-01-20  Niels Möller  <nisse@cuckoo.hack.org>

        * testsuite/Makefile.am (CLEANFILES): Delete test.in, test1.out
        and test2.out.

        than base64.

2002-12-30  Niels Möller  <nisse@cuckoo.hack.org>

        * testsuite/rsa2sexp-test.c: Don't include rsa.h (done by
        testutils.h, if enabled).
        * testsuite/sexp2rsa-test.c: Likewise.

        * rsa-decrypt.c: Make compilation conditional on WITH_PUBLIC_KEY.
        * rsa-encrypt.c: Likewise.

        * configure.ac: Generate config.m4.

        * x86/aes.asm: Use C for comments, include the tables using
        include_src, and commented out the key setup functions.
        Fixed the processing of the first handling of the round function.
        Now, encryption of a single block works! Multiple blocks, and
        decryption, is still broken.

        * x86/machine.m4: New file (empty).

        * x86/aes-encrypt.asm: New file, empty for now.

        * Makefile.am (%.asm): Added asm.m4, machine.m4 and config.m4 to
        the m4 command line.
        (libnettle_a_SOURCES): Added aes-encrypt-table.c.

        * sparc/aes.asm: No need to include asm.m4, that is taken care of
        by the Makefile.

        * config.m4.in: New file, configuration for asm.m4.

        * asm.m4 (C, include_src): New macros.

        * aes-encrypt-table.c: New file, table moved out from
        aes-encrypt.c.

2002-05-06  Niels Möller  <niels@s3.kth.se>

        * configure.in (asm_path): AC_CONFIG_LINKS adds $srcdir
        automatically.

2002-03-14  Niels Möller  <nisse@cuckoo.hack.org>

        * sparc/aes.asm, x86/aes.asm: Added copyright notice.

        * Makefile.am (libnettle_a_SOURCES): Added aes-internal.h.
        (EXTRA_DIST): Added assembler files.

        * configure.in (asm_path): Use $srcdir when looking for the files.
        * configure.in (asm_path): For now, disable x86 assembler code.
        Bumped version to 1.6.

2002-02-25  Niels Möller  <nisse@cuckoo.hack.org>

        * sparc/aes.asm (_aes_crypt): Moved increment of src into the
        source_loop. Also fixed stop condition, the loop was run 5 times,
        not 4, as it should.
        (_aes_crypt): Use src directly when accessing the source data,
        don't use %o5.
        (_aes_crypt): Renamed variables in source_loop.
        (_aes_crypt): Changed stop condition in source_loop to not depend
        on i. Finally reduced the source_loop to 16 instructions. Also
        increased the alignment of the code to 16.
        (_aes_crypt): In final_loop, use preshifted indices.
        (_aes_crypt): In final_loop, construct the result in t0. Use t0-t3
        for intermediate values.
        (_aes_crypt): In final_loop, use the register idx.
        (_aes_crypt): In final_loop, keep i multiplied by 4. Use key to
        get to the current roundkey.
        (_aes_crypt): In final_loop, use i for indexing.
        (_aes_crypt): Update dst in the output loop. This yields a delay
        slot that isn't filled yet.
        (_aes_crypt): Decrement round when looping, saving yet some
        instructions.
        (_aes_crypt): Reformatted code as blocks of four instructions
        each.
        (_aes_crypt): Copy the addresses of the indexing tables into
        registers at the start. No more need for the idx register.
        (_aes_crypt): Deleted idx register.
        (_aes_crypt): Some peep hole optimizations, duplicating some
        instructions to fill nop:s, and put branch instructions on even
        word addresses.

2002-02-22  Niels Möller  <nisse@cuckoo.hack.org>

        * sparc/aes.asm (_aes_crypt): Moved some more additions out of the
        inner loop, using additional registers.
        (_aes_crypt): Deleted one more addition from the inner loop, by
        using the subkey pointer.

2002-02-19  Niels Möller  <nisse@cuckoo.hack.org>

        * configure.in (asm_path): Renamed "path" to "asm_path". Also look
        for a machine.m4.

2002-02-16  Niels Möller  <nisse@cuckoo.hack.org>

        * sparc/aes.asm: Use that IDX2(j) == j ^ 2

        * Makefile.am (libnettle_a_SOURCES): Reordered aes-decrypt.c and
        aes-encrypt.c. For some strange reason it makes the benchmark go
        faster...

        * sparc/aes.asm (_aes_crypt): Use double-buffering, and no
        separate loop for adding the round key.
        (round): Keep round index muliplied by 16, so it can be used
        directly for indexing the subkeys.
        (_aes_crypt): In the final loop, use ctx+round to access the
        subkeys, no need for an extra register.

2002-02-15  Niels Möller  <nisse@cuckoo.hack.org>

        * sparc/aes.asm (_aes_crypt): Renaming variables, allocating
        locals starting from %l0.
        (_aes_crypt): Consistently use %l4, aka i, as the variable for the
        innermost loops.
        (_aes_crypt): Moved reading of ctx->nrounds out of the loop.
        (_aes_crypt): In final_loop, deleted a redundant mov, and use i as
        loop variable.
        (_aes_crypt): Started renumbering registers in the inner loop. The
        computation for the table[j] sub-expression should be kept in
        register %o[j].
        (_aes_crypt): Renamed more variables in the inner loop. Now the
        primary variables are t0, t1, t2, t3.

        * sparc/aes.asm (_aes_crypt): Swapped register %i0 and %o5, %i1
        and %o0, %i2 and %o4, %i3 and %o3, %i4 and %o2.
        (_aes_crypt): wtxt was stored in both %l1 and %l2 for the entire
        function. Freed %l2 for other uses.
        (_aes_crypt): Likewise for tmp, freeing register %o1.

        * sparc/machine.m4: New file, for sparc-specific macros.

        * sparc/aes.asm (_aes_crypt): Hacked the source_loop, to get rid
        of yet another redundant loop variable, and one instruction.
        (_aes_crypt): Strength reduce loop variable in the
        inner loop, getting rid of one register.
        (_aes_crypt): Use pre-shifted indices (aes_table.idx_shift), to
        avoid some shifts in the inner loop.
        (_aes_crypt): Don't check for nrounds==0 at the start of the loop.

        * asm.m4: Define and use structure-defining macros.

        * Makefile.am (%.asm): Use a GNU pattern rule, to make %.o depend
        on both %.asm and asm.m4.

        * aes-internal.h (struct aes_table): New subtable idx_shift.
        Updated tables in aes_encrypt.c and aes_decrypt.c.

        * asm.m4: Use eval to compute values.

        * sparc/aes.asm (_aes_crypt): Deleted commented out old version of
        the code.

        * asm.m4: Added constants for individual rows of the aes table.

        * aes.c (IDX0, IDX1, IDX2, IDX3): New macros, encapsualting the
        structure of the idx table.

        * asm.m4: Define various aes struct offsets.

        * testsuite/cbc-test.c (test_cbc_bulk): Use aes_set_encrypt_key
        and aes_set_decrypt_key.

        * sparc/aes.asm (_aes_crypt): Use symbolic names for the fucntion
        arguments.

        * sparc/aes.asm: Copied gcc assembler code for _aes_crypt.

        * aesdata.c: New program for generating AES-related tables.

        * testsuite/testutils.c (print_hex): New function (moved from
        yarrow-test.c).

        * testsuite/rsa-keygen-test.c (progress): Declare the ctx argument
        as UNUSED.

        * testsuite/cbc-test.c (test_cbc_bulk): New function, testing CBC
        with larger blocks.

        * yarrow256.c: Replaced uses of aes_set_key with

        algorithms with separate encyption and decryption key setup.

        * aes-internal.h (struct aes_table): New structure, including all
        constant tables needed by the unified encryption or decryption
        function _aes_crypt.

        * aes.c (_aes_crypt): New function, which unifies encryption and
        decryption.

        AES key setup now uses two separate functions for setting
        encryption and decryption keys. Applications that don't do
        decryption need no inverted subkeys and no code to generate them.
        Similarly, the tables (about 4K each for encryption and
        decryption), are put into separate files.

        * aes.h (struct aes_ctx): Deleted space for inverse subkeys. For
        decryption, the inverse subkeys replace the normal subkeys, and
        they are stored _in the order they are used_.

        * aes-set-key.c (aes_set_key): Deleted file, code moved...
        * aes-set-decrypt-key.c, aes-set-encrypt-key.c: New files,
        separated normal and inverse key setup.

        * aes-tables.c: Deleted, tables moved elsewhere...
        * aes-encrypt.c, aes-decrypt.c: New files; moved encryption and
        decryption funktions, and needed tables, into separate files.

2002-02-13  Niels Möller  <nisse@cuckoo.hack.org>

        * aes.c (aes_encrypt): Don't unroll the innerloop.
        (aes_encrypt): Don't unroll the loop for the final round.
        (aes_decrypt): Likewise, no loop unrolling.

        * aes-set-key.c (aes_set_key): Reversed the order of the inverted
        subkeys. They are now stored in the same order as they are used.

        * aes-tables.c (itable): New bigger table, generated by aesdata.c.

        * aes.c (aes_decrypt): Rewrote to use the bigger tables.

2002-02-12  Niels Möller  <nisse@cuckoo.hack.org>

        * aes-tables.c (dtbl): Replaced with table generated by aesdata.

        * aes.c (aes_encrypt): Rewrite, now uses larger tables in order to
        avoid rotates.

        * sparc/aes.asm (aes_encrypt): Strength reduced on j, getting rid
        of one register and one instruction in the inner loop.

        * sparc/aes.asm (idx, aes_encrypt): Multiplied tabled values by 4,
        making it possible to get rid of some shifts in the inner loop.

        * configure.in: Fixed spelling of --enable-assembler. Commented
        out debug echo:s.

        * asm.m4: New file. For now, only doing changequote and changecom.

        * sparc/aes.asm (aes_encrypt): Added comments.
        (aes_encrypt): Cut off redundant instruction per block, also
        saving one redundant register pointing to idx.
        (idx_row): New macro. Include asm.m4.

2002-02-11  Niels Möller  <nisse@cuckoo.hack.org>

        * sparc/aes.asm (key_addition_8to32): Cleaned up.
        Deleted gcc-generated debugging information.

        * sparc/aes.asm (key_addition32): First attempt at optimization.
        Made it slower ;-)

        * sparc/aes.asm (key_addition32): Unrolled loop, gained 4%
        speed, payed four instructions compared to gcc
        generated code.

        * Makefile.am (.asm.o): New rule for assembling via m4.
        (libnettle_a_SOURCES): Added new rsa and aes files.

        encryption.

        * aes-set-key.c, aes-tables.c: New files, split off from aes.c.
        Tables are now not static, but use a _aes_ prefix on their names.

        * aes-internal.h: New file.

        * cast128-meta.c (_NETTLE_CIPHER_FIX): Use _NETTLE_CIPHER_FIX.

        * cbc.c (cbc_decrypt_internal): New function, doing the real CBC
        procesing and requiring that src != dst.
        (cbc_decrypt): Use cbc_decrypt_internal. If src == dst, use a
        buffer of limited size to copy the ciphertext.

        * nettle-internal.c (nettle_blowfish128): Fixed definition, with
        key size in bits.

        * nettle-meta.h (_NETTLE_CIPHER_FIX): New macro, suitable for
        ciphers with a fixed key size.

        * examples/nettle-benchmark.c (display): New function for
        displaying the results, including MB/s figures.

        * sparc/aes.asm: New file. Not yet tuned in any way (it's just the
        code generated by gcc).
