They need to be more careful about using the word 'cryptography' then. Sure, crypto people and informed laypersons know this is hopelessly insecure, but all it takes is one overzealous intern implementing this in a banking application to cause a huge problem.
The only word I see is "encrypt", but regardless, this IS cryptography - converting to a code. You can encrypt with a Ceaser cipher, though it's not terribly secure.
