Subject: 2 Way encryption for password

Hi

I'm creating a password database (a dangerous thing to do, I know!)  
normally I'd hash the passwords for storage in the DB, but in this  
case I need to be able to also reverse them to their original state.  
I'm familiar with the digest module, but of course it isn't of use  
here. I didn't see anything obvious on my Google travels. Could  
anyone suggest how to perform encryption in ruby, in particular based  
on a rails application...?

Many thanks

Gabriel
