SRPServerInterface (src)

public class SimpleSRPServer

extends java.lang.Object

implements SRPServerInterface (src)

A simple hard coded implementation of SRPServerInterface that validates any given username to the password and salt provided to its constructor.

                                           java.rmi.RemoteException

Description copied from interface: SRPServerInterface (src)

Get the SRP parameters to use for this session and create an arbitrary session id to allow for multiple SRP sessions for this user.

Specified by:

getSRPParameters in interface SRPServerInterface (src)

Returns:

an array of {SRPParameters, Integer} where element[0] is the SRPParameters object and element[1] is the session id as an Integer.

Throws:

java.security.KeyException
