igrargpu - RAR GPU Password Recovery

This software on ATI RV 670/770/870 and nVidia "CUDA" video cards is used to recover passwords for RAR archives v 3.x. Recovery speed at HD4850 is about 20 times better than single core of Q6600 @ 2.4Ghz. (Comparing only optimized SSE2 code running on iCore. Currently only 2 programs heavily optimized for RAR 3.x recovery -- crark & ARCHPR). For non-optimized CPU versions it can be [place your favorite number here, like 100x or 200x].

Performance on nVidia cards slower than with ATI ones (because of nVidia GPU architecture). So, 8600 GT about 2x times faster than single core of Q6600 @ 2.4Ghz. GTX 260 /w 192SP about 12 times faster than single core of Q6600 @ 2.4Ghz.

Plain numbers (for RAR passwords with length == 4) are:
~168 passwords per second on single core of Q6600 @ 2.4Ghz (crark's result)
~325 passwords per second on 8600 GT
~3350 passwords per second on ATI HD4850
~2075 passwords per second on GTX260/192SP

Note that password recovery speed is not constant for RAR archive, it depends on password length (i.e shorter passwords will be checked faster than longer ones).
