fastmd5 is a 64-bit to-be-optimized md5 implementation in asm. The core md5 implementation is cross platform, but the source contains some Windows-only features for doing multi-threaded tests. Right now it only uses a static string but brute-force generated strings will come soon.

Goes well with utime for benchmarking your system
