It was at this time I was informed of H1kari's work in implementing the PBKDF2 hash function in hardware and showing massive gains in speed over a general purpose CPU. 1 card could compute 600 Keys/sec. He managed to hook us up with a box with 15 of these cards, effectivly doing over 9000 Keys/sec! What previously took Twitchy almost a month to compute, took H1kari 3 days. The end results barely fits on 9 DVD's and weighs in at about 33 Gb.
