The PSK is *NOT* encrypted, it's just in a hex format. Anyone can use
that string of hex bytes instead of a text passphrase, and still connect
to your PSK network.
(Every supplicant actually uses the hashed (hex-bytes) value in the
4-way handshake, not the text passphrase. Most allow you to type in
either. Certainly the XP supplicant allows you to type in either.)

Except it is stored as a LanMan hash by default (extraordinarily easy to
de-hash)... but that's a separate issue.

Not that I know of, but why would you want to use the same password
anyway? And if you aren't using the same password, would that make it a
lot less of a problem that it's saved in plain-text, because it isn't
used for anything else?
