Hello everyone, As you may know, Visa and MasterCard have some pretty extensive security requirements for merchants who accept a larger number of credit card transactions E.g. http://usa.visa.com/business/accepting_visa/ops_risk_management/cisp_merchan ts.html https://sdp.mastercardintl.com/documentation/index.shtml One of these requirements is cardholder data encryption -- is anyone aware of a PHP/MySQL/Linux/Apache solution for end-to-end cardholder data encryption that satisfies the Visa / MasterCard requirements?
