Crypt::DES may be overkill when all you want to encrypt is a 12 digit number, but it sounds so sexy when you say it to your customer, and it leaves them with a warm and fuzzy feeling.
DES encryption requires a secret key. So, why not enlarge the key to 12 digits and make it a one time pad. Customers will have a warmer fuzzy feeling from "perfect encryption".
Granted that you use a different, randomly generated key for each encryption, of course.
