No, it'll be a bit more work. The extra function added to DES_bs_b.c will also need to be added to the assembly files. I might get to that in June. > Speeds before: > Benchmarking: MSCHAPv2 C/R MD4 DES [mschapv2]...

One of the next steps (for this format) is to switch to using sse-intrinsics.c code for MD4. Alexander
