One-way hashing works great for passwords (and is in fact THE way to
store passwords in the DB). It doesn't work for anything else, as
usually you do want to have access to the data you've encrypted.

One of our customers who is big into security had a pretty good

data -
not the actual data itself. I am not certain which algorithm they were
talking about.

Joe had a few questions off-the-list (about how to do a query on an
encrypted value) and I'll try to update it soon, but that's the
current version I have.
Comments appreciated, as always.
