# HTTP server with SSL support using OpenSSL

This example creates a SSL server that returns a simple HTML page when you visit its root URL.

See the `esp_https_server` component documentation for 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.
