Andy Polyakov
22c268e6c9 Next generation aes-586.pl featuring AES_[en|de]crypt, accessing exclusively 
256 byte S-box. AES_cbc_encrypt needs further work as it should also use
slow routines when processing smaller amount of data.

af8c1d81a3 Reimplement outer rounds as "compact" in x86 assembler. This has rather 
strong impact on decrypt performance, 20-25%. One probably should consider
switching between slower and faster routines depending on how much data
we were asked to process.

985e4c4154 Mitigate the hazard of cache-collision timing attack on last round. The 
only chance for T[ed]4 to get evicted in this module is when its cache
"overlaps" with last 128 bits of key schedule.

9598fa8759 Mitigate the hazard of cache-collision timing attack on last round. Well, 
prefetch could have been moved closer to Td4 references. Something for
later consideration...

c8d5c71af5 Mitigate cache-timing attack in CBC mode. This is done by implementing 
compressed tables (2x compression factor) and by pre-fetching them into
processor cache prior every CBC en-/decryption pass. One can argue why
just CBC? Well, it's commonly used mode in real-life applications and
API allows us to amortize the prefetch costs for larger data chunks...
