This algorithm replaces the input with a null or empty value, depending on the context.
The algorithm's name is chosen for backward compatibility only. It does not perform any kind of lookup and is not related to the Secure Lookup framework.
For example:
-
"6379315274824970" → null
-
"ABCxyz123" → null
-
"Sí" → null
-
"999-12-3456." → null
-
"2000:a86f::1" → null
