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.
Before using the example, run make menuconfig
(or idf.py menuconfig
if using CMake build system) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in examples/protocols/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.
