Does anyone know how to implement the crypto-key.rb as found on

It allows for encryption and decryption of credit card numbers that
are stored in a database. I am somewhat new to Rails, and I don’t
always know how to use libraries and modules.

I’d recommend you check out ezcrypto. You can easily install it by:

gem install ezcrypto

Then to use it:

require ‘ezcrypto’

It does everything you need and much more. It also has decent
documentation with some clear examples. And if you have any question
I’d be glad to answer.
