Rev: src/nettle/ChangeLog:1.66
parent 3fb5009c
2002-02-12 Niels Mller <>
* 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.
* 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 Mller <>
* 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.
* (.asm.o): New rule for assembling via m4.
(libnettle_a_SOURCES): Added new rsa and aes files.
* New command line option --enable-assembler.
Selects assembler code depending on the host system.
* rsa-decrypt.c, rsa-encrypt.c: New files for rsa pkcs#1
* 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).
