public class SSHSignatureCallback extends Object implements Callback, Serializable
SSHSignatureCallback provides a Callback implementation used to perform SSH authentication. This callback is instantiated by the server with a random token which must be signed using the user's SSH private key.

It is the responsibility of the callback handler to invoke the sign method and return this object in response to the callback.
