2002-02-13 Niels Mller <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 Mller <nisse@cuckoo.hack.org>
* aes.c (aes_encrypt): Interleave computation and output in the
final round.
* aes-internal.h (AES_SMALL): New macro.
* aes.c (aes_encrypt): Optionally use smaller rotating inner loop.
* 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.
