Subject: scrypt
magnum, Rafael, all -
So I went ahead and implemented cleaner and better (but still far from
perfect) scrypt support for John the Ripper. Rafael - sorry for not
using your code, but I feel you learned scrypt while making it anyway,
and now you may see how my implementation differs.
I've attached patch against the core tree.
Speed on bull's FX-8120, one core:
Benchmarking: scrypt (16384, 8, 1) [Salsa20/8 128/128 XOP]... DONE
Raw: 37.0 c/s real, 37.0 c/s virtual
All cores:
Will run 8 OpenMP threads
Benchmarking: scrypt (16384, 8, 1) [Salsa20/8 128/128 XOP]... DONE
Raw: 209 c/s real, 26.2 c/s virtual
2x Xeon E5420:
Will run 8 OpenMP threads
Benchmarking: scrypt (16384, 8, 1) [Salsa20/8 128/128 SSE2]... DONE
Raw: 136 c/s real, 17.1 c/s virtual
2x Xeon E5649:
Will run 24 OpenMP threads
Benchmarking: scrypt (16384, 8, 1) [Salsa20/8 128/128 SSE2]... DONE
Raw: 380 c/s real, 16.1 c/s virtual
