  37  * a given host name:
  38  * @code
  39  * using boost::asio::ip::tcp;
  40  * namespace ssl = boost::asio::ssl;
  41  * typedef ssl::stream<tcp::socket> ssl_socket;
  42  *
  43  * // Create a context that uses the default paths for finding CA certificates.
  44  * ssl::context ctx(ssl::context::sslv23);
  45  * ctx.set_default_verify_paths();
  46  *
  47  * // Open a socket and connect it to the remote host.
  48  * boost::asio::io_context io_context;
  49  * ssl_socket sock(io_context, ctx);
  50  * tcp::resolver resolver(io_context);
  51  * tcp::resolver::query query("host.name", "https");
  52  * boost::asio::connect(sock.lowest_layer(), resolver.resolve(query));
  53  * sock.lowest_layer().set_option(tcp::no_delay(true));
  54  *
  55  * // Perform SSL handshake and verify the remote host's certificate.
  56  * sock.set_verify_mode(ssl::verify_peer);
  57  * sock.set_verify_callback(ssl::rfc2818_verification("host.name"));
  58  * sock.handshake(ssl_socket::client);
