RIPEMD-160 crypto hash implementations?

[Bruce Fitzsimons]

Hi list,

I've googled but I can't see any Erlang implementations of RIPEMD (original, 160, etc). Before I reimplement it badly, does anyone have one they'd like to share?

http://en.wikipedia.org/wiki/RIPEMD for those of you unfamiliar with it, it looks like a decent alternative to SHA-1(and happens to be the only optimised hash function available on the embedded device I'm working with).

Regards,
Bruce
