All Implemented Interfaces:

SSHPacketHandler, AuthMethod

public class AuthPublickey
extends KeyedAuthMethod

Implements the "publickey" SSH authentication method.

Requesteing authentication with this method first sends a "feeler" request with just the public key, and if the server responds with SSH_MSG_USERAUTH_PK_OK indicating that the key is acceptable, it proceeds to send a request signed with the private key. Therefore, private keys are not requested from the associated KeyProvider unless needed.
