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.

How to use example

Before project configuration and build, be sure to set the correct chip target using idf.py set-target <chip_name>.

Configure the project

idf.py menuconfig

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 for more details.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

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.
