Password hashing on FPGAs

Password cracking on FPGAs had been done before
Including by Pico Computing
We explored possible defensive use of FPGAs, as well as bcrypt cracking on FPGA
Yuri Gonzaga's Google Summer of Code 2011 project
Co-mentors: Solar Designer (Openwall), David Hulton (Pico Computing)
Yuri wrote and debugged Verilog code implementing bcrypt (including with Block RAMs), multiple bcrypt cores per chip, a tiny bcrypt-like construct (with intent to explore the possibility of fitting hundreds or thousands of these per chip)
We also considered reuse of Pico's fully-pipelined DES cores
