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
