verify

public boolean verify(SlaveComputer computer,
 HostKey hostKey,
 TaskListener listener)
               throws Exception

Description copied from class: SshHostKeyVerificationStrategy

Check if the given key is valid for the host identifier.

Specified by:

verify in class SshHostKeyVerificationStrategy

Parameters:

computer - the computer this connection is being initiated for

hostKey - the key that was transmitted by the remote host for the current connection. This is the key that should be checked to see if we trust it by the current verifier.

listener - the connection listener to write any output log to

Returns:

whether the provided HostKey is trusted and the current connection can therefore continue.

Throws:

Exception

getPreferredKeyAlgorithms

public String[] getPreferredKeyAlgorithms(SlaveComputer computer)
                                   throws IOException

Description copied from class: SshHostKeyVerificationStrategy

Provides a list of preferred key algorithms for this strategy and computer.

Overrides:

getPreferredKeyAlgorithms in class SshHostKeyVerificationStrategy

Returns:

a list of algorithms; empty or null lists will be ignored

Throws:

IOException
