Thanks for the information, especially the PCI Complancy link and info. Keith ----- Original Message ----- From: Bastien Koert To: Keith Spiller ; php-db@lists.php.net Sent: Tuesday, December 18, 2007 9:41 PM Subject: RE: [PHP-DB] Credit Card Encryption
Think very carefully about what you want to do here. PCI (payment card industry) has radically changed the rules about how CC data is stored in a networked environment. If your data environment is shared (shared web hosting), don't even think about it. There are a large number of rules that you need to follow to make your data systems PCI compliant [ http://www.pcicomplianceguide.org/ ] and they are not easy to follow. Things like strong encryption, code audits by qualified third parties etc. If you absolutely need to store the data (many of my large clients do this): 1. the database server should not be web facing, nor accessible internally by the web servers 2. the access (physical and electronic) should be extremely limited 3. the facility that holds the data should be hardened with limited controlled access 4. provide a cross reference number to the CC that other applications can use to replace the CC number If you are storing transactional data, just store the confirmation number that is returned by the payment gateway that you use. Let the payment gateway assume the risks of handling the data, its what they get paid for. If the data is for re-occurring payments, let the payment gateway handle it, many support these kinds of payments.
