public boolean verifyServerHostKey(java.lang.String hostname,
                                   int port,
                                   java.lang.String serverHostKeyAlgorithm,
                                   byte[] serverHostKey)
                            throws java.lang.Exception

The actual verifier method, it will be called by the key exchange code on EVERY key exchange - this can happen several times during the lifetime of a connection.

Note: SSH-2 servers are allowed to change their hostkey at ANY time.

Parameters:

hostname - the hostname used to create the Connection object

port - the remote TCP port

serverHostKeyAlgorithm - the public key algorithm (ssh-rsa or ssh-dss)

serverHostKey - the server's public key blob

Returns:

if the client wants to accept the server's host key - if not, the connection will be closed.

Throws:

java.lang.Exception - Will be wrapped with an IOException, extended version of returning false =)
