Go RPC over TLS.You have to create the following keys: certs/client.crt, certs/client.key, certs/server.crt, certs/server.key. client.crt and server.crt should be signed with ca.crt, which should be concatenated to both client.crt and server.crt. It's easier to do with easy-rsa: http://openvpn.net/index.php/open-source/documentation/howto.html#pki
