On: BLAKE2: “Harder, Better, Faster, Stronger” Than MD5

[floody-berry]

BLAKE2b is <3.5cpb on Sandy Bridge, or ~570mb/s at 2ghz. 5cpb in general on 64 bit x86, 400mb/s. 6-8 cpb in general on 32 bit x86 with SSSE3, 250-333mb/s. It definitely might be overkill for some situations, but it's fairly affordable overkill.
