+title: Enabling HTTPS
+---
+
+To enable SSL on the server side, please follow these steps:
+
+- Obtain SSL certificate file and private key file
+- Declare `struct mg_bind_opts`, initialize `ssl_cert` and `ssl_key`
+- Use `mg_bind_opt()` to create listening socket
+
+Example:
+
+```c
+int main(void) {
+  struct mg_mgr mgr;
+  struct mg_connection *c;
+  struct mg_bind_opts bind_opts;
+
+  mg_mgr_init(&mgr, NULL);
+
+  memset(&bind_opts, 0, sizeof(bind_opts));
+  bind_opts.ssl_cert = "server.pem";
+  bind_opts.ssl_key = "key.pem";
+
+  // Use bind_opts to specify SSL certificate & key file
+  c = mg_bind_opt(&mgr, "443", ev_handler, bind_opts);
+  mg_set_protocol_http_websocket(c);
+
+  ...
+}
+```
+
+For the full example, please see the [Simplest HTTPS server example](https://github.com/cesanta/dev/tree/master/mongoose/examples/simplest_web_server_ssl).
