The following example shows how to synchronously open a secure connection
to a given host name:
</p>
<pre class="programlisting">using boost::asio::ip::tcp;
namespace ssl = boost::asio::ssl;
typedef ssl::stream&lt;tcp::socket&gt; 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_context io_context;
ssl_socket sock(io_context, ctx);
tcp::resolver resolver(io_context);
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 ...
