clientFinalProcessor

public ScramSession.ClientFinalProcessor clientFinalProcessor(String password)
                                                       throws IllegalArgumentException

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 user's password.

Parameters:

password - The user's password

Returns:

The handler

clientFinalProcessor

public ScramSession.ClientFinalProcessor clientFinalProcessor(byte[] clientKey,
                                                              byte[] storedKey)
                                                       throws IllegalArgumentException

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:

IllegalArgumentException - If the message is null or empty
