Constructor Details

SRPServer

public SRPServer()
The basic constructor. Object is special, because it has no superclass, so there is no call to super().

Method Details

engineUnwrap

protected byte[] engineUnwrap(byte[] incoming,
                              int offset,
                              int len)
            throws SaslException
Overrides:
engineUnwrap in interface ServerMechanism

engineWrap

protected byte[] engineWrap(byte[] outgoing,
                            int offset,
                            int len)
            throws SaslException
Overrides:
engineWrap in interface ServerMechanism

evaluateResponse

public byte[] evaluateResponse(byte[] response)
            throws SaslException
Evaluates the response data and generates a challenge. If a response is received from the client during the authentication process, this method is called to prepare an appropriate next challenge to submit to the client. The challenge is null if the authentication has succeeded and no more challenge data is to be sent to the client. It is non-null if the authentication must be continued by sending a challenge to the client, or if the authentication has succeeded but challenge data needs to be processed by the client. SaslServer.isComplete() should be called after each call to evaluateResponse(),to determine if any further response is needed from the client.
Specified by:
evaluateResponse in interface SaslServer
Overrides:
evaluateResponse in interface ServerMechanism
Parameters:
response - the non-null (but possibly empty) response sent by the client.
Returns:
the possibly null challenge to send to the client. It is null if the authentication has succeeded and there is no more challenge data to be sent to the client.
Throws:
SaslException - if an error occurred while processing the response or generating a challenge.

getNegotiatedQOP

protected String getNegotiatedQOP()
Overrides:
getNegotiatedQOP in interface ServerMechanism

getNegotiatedRawSendSize

protected String getNegotiatedRawSendSize()
Overrides:
getNegotiatedRawSendSize in interface ServerMechanism

getNegotiatedStrength

protected String getNegotiatedStrength()
Overrides:
getNegotiatedStrength in interface ServerMechanism

getReuse

protected String getReuse()
Overrides:
getReuse in interface ServerMechanism

initMechanism

protected void initMechanism()
            throws SaslException
Overrides:
initMechanism in interface ServerMechanism

resetMechanism

protected void resetMechanism()
            throws SaslException
Overrides:
resetMechanism in interface ServerMechanism
