I'm getting 150-160 c/s on 8 threads(omp) using a Cwgwin\win32 build (Intel
Xeon E5620@...0GHz)
c:\john-1.7.9-jumbo-7\run>john-omp.exe brulez.txt -format=rar -pot=rar.pot
Loaded 3 password hashes with 3 different salts (RAR3 SHA-1 AES [32/32])
guesses: 0  time: 0:00:00:02 0.00%  c/s: 150  trying: carolina - david
guesses: 0  time: 0:00:00:04 0.00%  c/s: 151  trying: alyssa - horses
I've got more resources to throw around, but if the nature of the password
is unknown, at these speeds I don't know if it will help.
