maskCC UDF - Strips all credit card variations from a string. Useful when sending/storing user-submitted data in order to remain compliant with VISA Payment Card Industry Data Security Standard (PCI DSS) requirements

The maskCC user-defined function &#x28;UDF&#x29; takes a text string as input, searches for patterns that resemble credit card numbers, attempts to validate these potential numbers using ColdFusion&apos&#x3b;s built-in credit card validation, and then masks the validated numbers by replacing all but the last four digits with asterisks.
