Frequently Asked Question
How does encrypted cardholder data impact PCI DSS scope?
Encryption of cardholder data with strong cryptography is an acceptable method of rendering the data unreadable according to PCI DSS Requirement 3.5.1. However, encryption alone is insufficient to render the cardholder data out of scope for PCI DSS.
For more information, refer to PCI DSS v4.0 section 4 Scope of PCI DSS Requirements, subsection Encrypted Cardholder Data and Impact on PCI DSS Scope.
