As mentioned above, I've already created descrypt application for FPGA and that works in simulator. That includes onboard hash comparsion. I estimate its performance at no less than 140 MH/s per chip (560 MH/s per board) and there's enough room for various optimizations.
Now I'm planning to:
- attach I/O;
- create JtR format, develop JtR integration;
- create on-chip candidate generator. I'm considering mask mode.
