Class ClientFinalMessage
java.lang.Object
com.ongres.scram.common.message.ClientFinalMessage
- All Implemented Interfaces:
StringWritable
Constructs and parses client-final-messages. Formal syntax is:
client-final-message-without-proof = channel-binding "," nonce ["," extensions]
client-final-message = client-final-message-without-proof "," proof
Note that extensions are not supported.- See Also:

ClientFinalMessage
Constructus a client-final-message with the provided gs2Header (the same one used in the client-first-message), optionally the channel binding data, and the nonce. This method is intended to be used by SCRAM clients, and not to be constructed directly.- Parameters:
gs2Header
- The GSS-API headercbindData
- If using channel binding, the channel binding datanonce
- The nonceproof
- The bytes representing the computed client proof

writeToWithoutProof
Returns a StringBuffer filled in with the formatted output of a client-first-message without the proof value. This is useful for computing the auth-message, used in turn to compute the proof.- Parameters:
gs2Header
- The GSS-API headercbindData
- The optional channel binding datanonce
- The nonce- Returns:
- The String representation of the part of the message that excludes the proof
-
writeTo
Description copied from interface:StringWritable
Write the class information to the given StringBuffer.- Specified by:
writeTo
in interfaceStringWritable
- Parameters:
sb
- Where to write the data.- Returns:
- The same StringBuffer.
