Method Detail

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
