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

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

        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

        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.

        interleaving independent operations.

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

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

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

        * 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
        for aes.asm, aes-encrypt.asm and aes-decrypt.asm.

        * configure.ac (OBJDUMP): Use AC_CHECK_TOOL to check for objdump.
        (ASM_MARK_NOEXEC_STACK): Use $OBJDUMP when examining the object file.

        function, analogous to _nettle_aes_encrypt.

2005-10-14  Niels Möller  <niels@s3.kth.se>

        * aes-internal.h (AES_ROUND, AES_FINAL_ROUND): New macros.

        substitute the value of ASM_MARK_NOEXEC_STACK at the end of each
        assembler file.

        * configure.ac (ASM_MARK_NOEXEC_STACK): Check if the C compiler
        generates a .note.GNU-stack section. If so, we should do the same
        in our assembler files.

        * Makefile.in (distdir): Use a loop to pick up the contents of
        $(DISTFILES) from source and build directories. For some reason,
        $? failed to find stamp-h.in in the source directory.

2005-10-05  Niels Möller  <nisse@lysator.liu.se>

        * x86/aes-decrypt.asm: Use C_NAME(_nettle_aes_decrypt_table) when

        * configure.ac (NM): Use AC_CHECK_TOOL to check for nm.
        (ASM_SYMBOL_PREFIX): Use $NM when examining the object file.
        (ASM_ELF_STYLE): New variable. Set to 'yes' if assembling a file

        mode, which doesn't handle latin-1 properly. Set UPDATED-FOR to
        1.13. Updated copyright years, and introduced a COPYRIGHT-YEARS
        symbol. Updated copyright section, to mention assembler
        implementations.

        override aes.c, which isn't needed for the x86 implementation.

        * configure.ac (SHLIBMINOR): Increased minor number. Library
        version is now libnettle.so.2.4, soname still libnettle.so.2.

        * examples/nettle-benchmark.c (main): Reordered hash benchmarks.

        * 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.

2005-10-03  Niels Möller  <nisse@lysator.liu.se>

        * x86/sha1-compress.asm (OFFSET): New macro.
        (F3): Eliminated a movl.

        * x86/sha1-compress.asm (_nettle_sha1_compress): Do byte order
        conversion, and store the input data on the stack. This leaves one
        more register free for other uses.

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

2005-09-28  Niels Möller  <niels@s3.kth.se>

        * sha1.c (sha1_final): Call sha1_block, don't call the compression

        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

        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

        /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>

        * 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.

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

        * x86/sha1-compress.asm: Store the magic constants on stack.

        sha1-compress.asm.

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

        * 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

        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.

        rsa-decrypt.

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

        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.

        Constification. Some bugfixes.

        * Use "config.h", not <config.h>.

        from draft-ietf-ipsec-ciph-sha-256-01.txt.

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

        * 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.

        * 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.

        * 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>

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.

        needed to get a correct, positive, sign. For %b, use
        nettle_mpz_sizeinbase_256_s, to handle negative numbers properly.

        * bignum.c (nettle_mpz_sizeinbase_256_s): New function.
        (nettle_mpz_sizeinbase_256_u): New name, was

        allocated for wtxt, so that we stay clean of the reserved %g
        registers.

2002-05-14  Niels Möller  <nisse@cuckoo.hack.org>

        * sparc/aes.asm: Avoid using %g6 and %g7, as they are reserved for

        encrypt more than one block at a time.

2002-05-07  Niels Möller  <niels@s3.kth.se>

        * 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.

        * 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.

        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>

        * 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.

        * 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

        * 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.

        * 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>

        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).
