MD5 technology is very different from the patented public key encyption.
It's just a secure hash function. There are others -- SHS, MD4, etc.

Anyway... the md5 source code is all over the place. There's an md5
module in the Python distribution, so I'm pretty sure there are no
prohobitive licensing restrictions.
