Never store CC numbers in the clear.. At least use something
like pgp to keep out the curious. I suggest a multi level
approach. Store the last 4 digits of a credit card as
text in ldap so a person using a web site can identify the
credit card they saved in your system. The real credit card
number should be pgp encrypted with at least 2048 bit key
and then stored in ldap. You would store the private
key safely on a seperate highly hardened and protected system which
has the capability of processing the credit card transactions.
