Any way to get the WEP/WPA password off an automatically connected computer?

Hey, the computers in the library at my school connect automatically to the wireless network. Me and my friend don't really want to use those computers, though, because he has a laptop and I have my iPod. Is there a way to grab the WEP/WPA information off the machine?

Extremely doubtful, as this is their security. But, you can turn off your wireless access, if your not interested in using it.

Well, I have access to the computer through my student account; I can run the terminal, and do anything else that doesn't require an admin password. I could probably obtain one, but I don't want to get in serious trouble for that; if there's an easy way to just use a command line unix tool or something, I'd be really grateful.

The passwords on a system can be made visible through Keychain Assistant or through System Preferences, but you have to have administrator rights on the computer, which you clearly don't.

Please don't request help in hacking or gaining unauthorized access to someone else's computer network here.
