Extension point to allow sub classes to optionally do some processing after a user has been created or enabled . For example they could set something in the session so that the authentication success handler can treat the first log in differently .

Take input string and create the instance . As of version 1 . 3 . 2 forward the case of the INPUT is not relevant . Note however that when the Checksum CCCCCC is computed the hex hhhhhh - string is LOWER CASE .
