Based on Extensible Algorithm Framework

The EmailLookup algorithm is an instance of the Secure Lookup Algorithm Framework.


A new email framework and two new email algorithm instances were introduced in version and are the preferred methods for masking email values. See Email, Email SL, and Email Unique for more information.

This algorithm performs a lookup on the input value and returns a value from the provided lookup file. It is possible for this algorithm to produce the same output value for different input values. Inputs to this algorithm are case-sensitive so two inputs with the same value in different cases may mask to different values. Leading and trailing whitespaces are preserved by this algorithm.

The lookup values for this algorithm are non-resolving email addresses.

For example:

  • "" → ""
  • "" → ""
  • "" → ""
