There is some proprietry "magic" as well as salting but that part doesn't look slow. Other than that, sapG is 2xSHA1 and sapB is 2xMD5. I presume it would be a walk in the park (for guys like JimF or Bartavelle if they had time/incentive) to utilise the existing intrinsics or asm funtions, for a decent boost. And this could/should still be combined with OMP. magnum
