There was a plan to add the whole Cryptography package (split to three
packages) to the Trunk. Some older versions are waiting in the Inbox (see 
CryptoCore, CryptoCerts and CryptoExtras). IIRC this process is stalled 
because the proper renaming of the packages didn't happen (Cryptography 
instead of Crypto). If the renaming is done, then Squeak will have a 
working MD5 implementation out of the box.

Another solution is to grab the MD5 implementation from WebClient (which 
is probably the same as in Croquet, since it uses the CroquetPlugin if 
available).

What do you think?
