There is a simple alternative that you might not be aware of, and that is use Advantage Database (I am assuming that you are using MySQL right now). You can get a free version to try and it provides encryption at the table level. There is a PHP interface for it and everything can be found at www advantage-database.com and go the the developers download area. I have been using it in my everyday development for about 4 years and I love it. I just recently saw that they offer a PHP interface to it as well as an ODBC, VB, Delphi, C++ Builder, JBuilder etc. Store the credit card info in Advantage and leave the rest of your data where you have it. Just a thought...

Isn't there any method (free, preferably) of ASSYMETRIC (Public key) cryptography I can use with PHP to store this data in a db?? Or is there any other good option instead of this?
