          byte[] i_s,
          byte[] i_c)
   throws 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 initialization packet

i_c - the client key initialization packet

Throws:

Exception - if an error occurs

next

boolean next(int cmd,

      throws Exception

Process the next packet

Parameters:

cmd - the command

buffer - the packet contents positioned after the command

Returns:

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

Throws:

Exception - if an error occurs

getHash
