Class SRP6SaslServer

Implemented Interfaces:

public class SRP6SaslServer
extends SRP6TLSServer

A variation of the SRP-6 protocol as used in the SASL-SRP mechanism, for the Host (server side).

In this alternative, the exchange goes as follows:

     C -> S:  I                      (identifies self)
     S -> C:  N, g, s, B = 3v + gˆb  (sends salt, b = random number)
     C -> S:  A = gˆa                (a = random number)

All elements are computed the same way as in the standard version.
