Subject: OpenCL implementation of ZIP AES file format
Hi,
I have written OpenCL implementation of ZIP AES file format. Patch
(against magnum-jumbo) attached. Thanks to Lukas for PBKDF2 kernel.
$ ../run/john -fo:zip-opencl -t # ATI 6970
OpenCL platform 0: AMD Accelerated Parallel Processing, 2 device(s).
Using device 0: Cayman
Benchmarking: ZIP-AES PBKDF2-HMAC-SHA-1 [OpenCL]... DONE
Raw: 124540 c/s real, 2764K c/s virtual
$ ../run/john -fo:zip -t # AMD X3 720 CPU (1 core).
Benchmarking: WinZip PBKDF2-HMAC-SHA-1 [32/64]... DONE
Raw: 642 c/s real, 642 c/s virtual
Speedup obtained (over single core): ~194x
