There was a Cryptography team a few years ago with a few devs and big 
plans, but the team disappeared somehow... Anyway we have some usable 
code and a lot of half baked stuff here: 
Start with Cryptography-cmm.11.mcz if you're interested.

People are usually looking for three stuff:
- hashes (MD5, SHA1, etc). These work pretty well. I think MD5 should be 
added to Squeak in the future. 
- SSL. It's somewhat broken (has issues with certificates IIRC) and really 
slow if used without the DESPlugin. The Cobalt developers forked the 
Cryptography package and fixed lots of stuff about SSL. But if you just 
want to fetch a few web pages, you better try curl first.
- SSH. That's pre-alpha. :)
