Method Detail

init

void init(AbstractSession session,
        byte[] V_S,
        byte[] V_C,
        byte[] I_S,
        byte[] I_C)
          throws java.lang.Exception

Initialize the key exchange algorithm.

Parameters:

session - the session using this algorithm

V_S - the server identification string

V_C - the client identification string

I_S - the server key init packet

I_C - the client key init packet

Throws:

java.lang.Exception - if an error occurs

next

             throws java.lang.Exception

Process the next packet

Parameters:

buffer - the packet

Returns:

a boolean indicating if the processing is complete or if more packets are to be received

Throws:

java.lang.Exception - if an error occurs
