I know GPUs aren't magically faster than CPUs, only better suited for particular workloads, but that's completely fascinating. > Are you saying that benchmark gives you 2k c/s, but actual run only > 100 c/s?

I hadn't been paying close enough attention to Dhiru's work so wasn't aware he was already working on some of those. For those that can be readily implemented on the GPU (those that exercise an actual hash?) and don't intersect Dhiru's work, I'd still be interested. The FileVault (versions 1 and 2) suggestion is very interesting, as would perhaps be LUKS.
