Bill, please note that Esteban just needs a standard hash algorithm.
No encryption.

Some time ago we discussed including hash functions from Cryptography
in Pharo core. We postponed it then because it seemed that maybe some
people would join and make Cryptography work in Pharo. An OpenSSL
interface would be a very interesting alternative too.

In any case I think we should add MD5 and maybe some other hash
functions to the core. Will add this to my todo list.
