No, Crypt::CreditCard uses AES, which is a symmetric cipher. But it cleverly uses the user password as part of the encryption process (and ideally that password should not be available to the system unless the user is logged on), so it's a good method to use when you need access to the credit card number from the website with user interaction.

Still, given that it's marked as non-production I would say Andre should not use it unless he's not intending his system to go into production.


There are ten types of people: those that understand binary and those that don't.
