Slide 57

Update: we've since implemented bcrypt on ZTEX 1.15y quad-FPGA boards (which was mentioned as part of "Future work" on slide 57 here), achieving much higher speeds than anything shown here (over 100k c/s at bcrypt cost 5 per board, over 1.6M c/s on a 16-board cluster managed from one Raspberry Pi). We've also implemented a number of other hash types on those boards, with support for all of that merged into John the Ripper bleeding-jumbo branch and available for actual use (not just research).
