The Cryptohaze Multiforcer supports CUDA, OpenCL, and CPU code (SSE, AVX, etc). All of this is aimed at either the pentester who can’t spray hashes to the internet, or the hacker who would rather not broadcast what she obtained to pastebin scrapers. The tools run on all platforms that support CUDA or OpenCL (currently Windows, Linux, OS X) If you don’t have a GPU – the OpenCL code will run just fine on your host CPU!
