The LastCommaFirstLookup algorithm is an instance of the Secure Lookup Algorithm Framework.
A new full name framework was introduced in version 22.214.171.124 and is the preferred methods for masking full name values. See Full Name 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 full names in the format Last Name, First Name.
"Lincoln, Abe" → "Campbell, Allison"
"George Washington" → "Douglas, Alfred"
"teddy" → "Smith, Jack"
