Hi Johan,

Somehow I thought the Pharo's version of Blowfish was ported to GemStone,
since the developer is Paul DeBruicker, but maybe it is not :(

Thanks, yes, I noticed we have SecureHashAlgorithm in GemStone.

Would be nice to have SHA256 :)

Yes. Maybe (if it is just the Smalltalk part) it is not difficult to port.
What I am not sure is that sometimes these algorithms assumes the size of
the world (32 bits or 64 bits)... so that would be a difference between
Pharo and GemStone.
I will see if I can make it work.

Thanks Johan,
