That's nice for your personal files -- is there something similarly simple with an escrow option? I.e. Bob encrypted a bunch of critical files and left the company. While I don't want someone that hacks into the server to be able to decrypt them (so the key must be kept in a separate location, like Bob's head) I do want to make sure I can decrypt the files under those special circumstances, but they have to be stored in a way that makes them hard to get.
