OK, now for some absolutely incredible performance.
Credit to tcatm for the caching part of the SHA context - this offers absolutely brilliant performance. Additionally, the Intel compiler really comes into its own here as its parallelisation abilities give a massive performance boost over Visual Studio.
Performance: 4700khash/s on 4 cores, I think that speaks for itself.
I’ve included both the VS and Intel build, but there’s really no comparison, the Intel build craps all over VS.
