507 /**
508 * After a successful connect, one has to authenticate oneself. The
509 * authentication method "publickey" works by signing a challenge sent by
510 * the server. The signature is either DSA or RSA based - it just depends on
511 * the type of private key you specify, either a DSA or RSA private key in
512 * PEM format. And yes, this is may seem to be a little confusing, the
513 * method is called "publickey" in the SSH-2 protocol specification, however
514 * since we need to generate a signature, you actually have to supply a
515 * private key =).
516 * <p>
517 * If the authentication phase is complete, <code>true</code> will be
518 * returned. If the server does not accept the request (or if further
519 * authentication steps are needed), <code>false</code> is returned and
520 * one can retry either by using this or any other authentication method
521 * (use the <code>getRemainingAuthMethods</code> method to get a list of
522 * the remaining possible methods).
523 *
524 * @param user
525 * A <code>String</code> holding the username.
526 * @param pair
527 * A <code>RSAPrivateKey</code> or <code>DSAPrivateKey</code>
528 * containing a DSA or RSA private key of
529 * the user in Trilead object format.
530 *
531 * @return whether the connection is now authenticated.
