 34/// Verifies a certificate against a hostname according to the rules described
 35/// in RFC 2818.
 36/**
 37 * @par Example
 38 * The following example shows how to synchronously open a secure connection to
 39 * a given host name:
 40 * @code
 41 * using boost::asio::ip::tcp;
 42 * namespace ssl = boost::asio::ssl;
 43 * typedef ssl::stream<tcp::socket> ssl_socket;
 44 *
 45 * // Create a context that uses the default paths for finding CA certificates.
 46 * ssl::context ctx(ssl::context::sslv23);
 47 * ctx.set_default_verify_paths();
 48 *
 49 * // Open a socket and connect it to the remote host.
 50 * boost::asio::io_service io_service;
 51 * ssl_socket sock(io_service, ctx);
 52 * tcp::resolver resolver(io_service);
 53 * tcp::resolver::query query("host.name", "https");
 54 * boost::asio::connect(sock.lowest_layer(), resolver.resolve(query));
 55 * sock.lowest_layer().set_option(tcp::no_delay(true));
 56 *
 57 * // Perform SSL handshake and verify the remote host's certificate.
 58 * sock.set_verify_mode(ssl::verify_peer);
 59 * sock.set_verify_callback(ssl::rfc2818_verification("host.name"));
 60 * sock.handshake(ssl_socket::client);
 61 *
 62 * // ... read and write as normal ...
 63 * @endcode
