The passphrase gets hashed to the actual hex key, which is what's
actually used to connect.  However, that should be fine, because NM
won't *rehash* it once it's already hashed.

Actually, the hashed password is currently expected.  Since hashing is
one-way, the passphrase is pretty much lost.  Yes, I'd like to fix that
because it confuses a heck of a lot of people.

If the connection fails, is the hashed password shown in the box always
the same, or does it keep changing?
