public class ManuallyTrustedKeyVerificationStrategy
extends SshHostKeyVerificationStrategy

A host key verification strategy that works in a similar way to host key verification on Unix/Linux this host (depending on how this strategy has been configured), and manual verification if the key provided by the remote host differs from the one currently saved in as the known key for this host. This manual verification is achieved through adding a TrustHostKeyAction to the Computer the connection is being initiated for that can be actioned by a user with the appropriate permission to add a new key or replace an existing key in the known hosts database.

               throws IOException

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:

IOException

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
