I had never looked into this until recently, and I felt really stupid
for it not having occurred to me. Most sytems enrypt the password in a
way to where you purposely CAN'T decrypt it. Later, when the user logs
in, they encrypt whatever the user typed for the password, and compare
that to the stored encrypted password.

I don't know if there's anything in the stock library that will do
reversible encryption. Anyone know?
