getSRPParameters

public Object[] getSRPParameters(String username,
                                 boolean mutipleSessions)
                          throws KeyException,
                                 RemoteException

Description copied from interface: SRPServerInterface

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

Returns:

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

Throws:

KeyException

RemoteException

init

public byte[] init(String username,
                   byte[] A,
                   int sessionID)
            throws SecurityException,
                   NoSuchAlgorithmException,
                   RemoteException

Description copied from interface: SRPServerInterface

Initiate the SRP algorithm. The client sends their username and the public key A to begin the SRP handshake.

Specified by:

init in interface SRPServerInterface

Returns:

byte[], ephemeral server public key B = (v + g ^ b) % N

Throws:

SecurityException

NoSuchAlgorithmException

RemoteException

verify

public byte[] verify(String username,
                     byte[] M1,
                     int sessionID)
              throws SecurityException,
                     RemoteException

Specified by:

                     RemoteException

Description copied from interface: SRPServerInterface

Verify the session key hash. The client sends their username and M1 hash to validate completion of the SRP handshake.

Specified by:

verify in interface SRPServerInterface

M2, the server hash of the client challenge; M2 = H(A | M1 | K)

Throws:

SecurityException

RemoteException
