I would highly recommend taking a look at how Oracle is handling
encryption in the database in 10.2 (or whatever they're calling it).
They've done a good job of thinking out how to handle things like
managing the keys.
I know that Oracle magazine did an article on it recently; you should be
able to find that online somewhere.
