Generates a ScramSession.ClientFinalProcessor, that allows to generate the client-final-message and also receive and parse the server-first-message. It is based on the clientKey and storedKey, which, if available, provide an optimized path versus providing the original user's password.

Parameters:

clientKey - The client key, as per the SCRAM algorithm. It can be generated with: ScramFunctions.clientKey(ScramMechanism, StringPreparation, String, byte[], int)

storedKey - The stored key, as per the SCRAM algorithm. It can be generated from the client key with: ScramFunctions.storedKey(ScramMechanism, byte[])

Returns:

The handler

Throws:

java.lang.IllegalArgumentException - If the message is null or empty
