It's not paranoia if they really are out to get you.

I think you have a problem. Good work encrypting what's in the database, but you are still vulnerable before the data is encrypted and after the data is unencrypted.

You don't specify your network setup (again, good work), but I strongly advise you to investigate the program "ettercap". I know it's in the ports collection on FreeBSD; I assume it's available for Linux, too. It lets you do ARP poisoning man-in-the-middle attacks on known machines. It also conveniently sniffs SSL data and SSH1 data; if your data can be intercepted, ettercap will probably show it.

Please note, though: ettercap will set off intrusion-detection alarms in well-run networks. Running such a program is grounds for termination in some companies. Inform the authorities before you use it.

BTW, once you figure out how ettercap works, you will never again log on to your bank account from a coffeehouse. =)
