Method Details
- init
  
  void init(Transport trans, String V_S, String V_C, byte[] I_S, byte[] I_C) throws GeneralSecurityException, TransportException
  
  Initialize the key exchange algorithm.
  
  Parameters:
  
  trans - the transport
  
  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:
  
  GeneralSecurityException
  
  TransportException - if there is an error sending a packet
- getH
  
  byte[] getH()
  
  Returns:
  
  the computed H parameter
- getK
  
  BigInteger getK()
  
  Returns:
  
  the computed K parameter
- getHash
  
  Digest getHash()
  
  The message digest used by this key exchange algorithm.
  
  Returns:
  
  the message digest
- getHostKey
  
  PublicKey getHostKey()
  
  Returns:
  
  the host key determined from server's response packets
- next
  
  boolean next(Message msg, SSHPacket buffer) throws GeneralSecurityException, TransportException
  
  Process the next packet
  
  Parameters:
  
  msg - message identifier
  
  buffer - the packet
  
  Returns:
  
  a boolean indicating if the processing is complete or if more packets are to be received
  
  Throws:
  
  GeneralSecurityException
  
  TransportException - if there is an error sending a packet
