Other than that, sapG is 2xSHA1 and sapB is 2xMD5.

And this could/should still be combined > with OMP. I added SSE/MMX/intrinsics to sapB, including with OMP. It's at least 2.5x faster now, near 10000K c/s on my old dual-core laptop. The patch should be in next Jumbo but is currently only available from github: https://github.com/magnumripper/magnum-jumbo Will do sapG in the next few days. Note that I only have the built-in self-tests - these formats are not included in our Test Suite. Please test, and report any problems (or lack thereof). magnum
