Class SRP6SaslClient

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

In this alternative, the exchange goes as follows:

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

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