Description copied from interface: HostKeyVerifier

This callback is invoked when the server's host key needs to be verified. The return value indicates to the caller whether the SSH connection should proceed.

Note: host key verification is the basis for security in SSH, therefore exercise due caution in implementing!

Specified by:

verify in interface HostKeyVerifier

Parameters:

hostname - remote hostname

port - remote port

key - host key of server

Returns:

true if key is acceptable, false otherwise
