  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
