thank you for sharing, i'm sure many, including myself will
study/experiment, and attempt to optimize it further - test concept
with other algorithms such as md4/sha-1

you say that it would be possible to omit the bit rotations, would it
also be possible to pre-compute constant additions and store these in
memory? rather than process at runtime.

thanks!
