        throws SaslException

Method Detail

createInitialResponse

public byte[] createInitialResponse()
                             throws SaslException

Netscape specific function.

SaslException

evaluateChallenge

public byte[] evaluateChallenge(byte[] challengeData)
                         throws SaslException

Processes the challenge data. The server sends a challenge data using which the client must process using GSS_Init_sec_context. As per RFC 2222, when GSS_S_COMPLETE is returned, we do an extra handshake to determine the negotiated security protection and buffer sizes.

Parameters:

challengeData - A non-null byte array containing the challenge data from the server.

Returns:

A non-null byte array containing the response to be sent to the server.
