* @par Example
|
|
* The following example shows how to synchronously open a secure connection to
|
|
* a given host name:
|
|
* @code
|
|
* using asio::ip::tcp;
|
|
* namespace ssl = 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.
|
|
* asio::io_context io_context;
|
|
* ssl_socket sock(io_context, ctx);
|
|
* tcp::resolver resolver(io_context);
|
|
* tcp::resolver::query query("host.name", "https");
|
|
* 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::host_name_verification("host.name"));
|
|
* sock.handshake(ssl_socket::client);
|
|
*
|
|
* // ... read and write as normal ...
