 * @par Example
 * The following example shows how to synchronously open a secure connection to
 * a given host name:
 * @code
 * using boost::asio::ip::tcp;
 * namespace ssl = boost::asio::ssl;
 * typedef ssl::stream<tcp::socket> ssl_socket;
 *
 * // Create a context that uses the default paths for finding CA certificates.
 * ssl::context ctx(ssl::context::sslv23);
 * ctx.set_default_verify_paths();
 *
 * // Open a socket and connect it to the remote host.
 * boost::asio::io_service io_service;
 * ssl_socket sock(io_service, ctx);
 * tcp::resolver resolver(io_service);
 * tcp::resolver::query query("host.name", "https");
 * boost::asio::connect(sock.lowest_layer(), resolver.resolve(query));
 * sock.lowest_layer().set_option(tcp::no_delay(true));
 *
 * // Perform SSL handshake and verify the remote host's certificate.
 * sock.set_verify_mode(ssl::verify_peer);
 * sock.set_verify_callback(ssl::rfc2818_verification("host.name"));
 * sock.handshake(ssl_socket::client);
 *
 * // ... read and write as normal ...
