I want to build the following scenario (with gnutls) One archtecture client-server (in lan)... when client open the connection with server, it be used TLS with autentication PGP-based. It is possible to start from ex-serv-anon and ex-client1. isn't it? There is some reference on this mechanism? (this is gnutls mechanism)
