# HTTP Websocket server with SSL support
|
|
|
|
This example creates a SSL server and employs a simple Websocket request handler. It demonstrates handling multiple clients from the server including:
|
|
* PING-PONG mechanism
|
|
* Sending asynchronous messages to all clients
|
|
|
|
See the `esp_https_server` component documentation for details.
|
|
|
|
Before using the example, open the project configuration menu (`idf.py menuconfig`) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.

## Certificates
|
|
|
|
You will need to approve a security exception in your browser. This is because of a self signed
|
|
certificate; this will be always the case, unless you preload the CA root into your browser/system
|
|
as trusted.
|
|
|
|
You can generate a new certificate using the OpenSSL command line tool:
|
|
|
|
```
|
|
openssl req -newkey rsa:2048 -nodes -keyout prvtkey.pem -x509 -days 3650 -out cacert.pem -subj "/CN=ESP32 HTTPS server example"
|
|
```
|
|
|
|
Expiry time and metadata fields can be adjusted in the invocation.
|
|
|
|
Please see the openssl man pages (man openssl-req) for more details.
|
|
|
|
It is **strongly recommended** to not reuse the example certificate in your application;
|
|
it is included only for demonstration.
