The

masking

task generates a logically valid credit card number when it masks a valid credit card number. The length of the source credit card number must be from 13 through 19 digits. The input credit card number must have a valid checksum based on credit card industry rules.

The first six digits of a credit card number identify the credit card issuer. You can keep the original credit card issuer or you can select another credit card issuer to appear in the masking results.

The following examples of credit card numbers are in valid formats:

4567893453452

4567 8934 5345 2

4567-8934-5345-2

4567-8934-5345-2657

4567 8934 5345 2657

The following examples of credit card numbers are not in valid formats:

4563 x567 5674 7432

4563#7587 4666 9876

If the source does not contain a valid format, the task replaces with default values from the

defaultValue.xml

file.
