I am trying to connect from an ESP32 to my MQTT broker with a self-signed certificate.

. This article delves into the realm of secure firmware updates by exploring how to implement self-OTA (Over-The-Air) updates for ESP32 devices using HTTPS (SSLTLS) with a trusted self-signed certificate. g.

secureServer new HTTPSServer (cert); Then we will declare ResourceNodes for two routes, where we will exemplify how to return HTTP response codes other than 200.

Naturally, this should only be used for testing purposes. Summarized Code on the ESP32 WiFiClientSecure secureClient; PubSubClient client (secureClient); secureClient.

This way, you can use tried and true HTTPS (instead of reinventing the wheel), your client authenticates the server (as it should in any secure system) using the pinned cert. .

Self-Signed Certificates.
We can use Self-signed certificate in our DIY IoT projects or in local network.

Note To create a code signing certificate, install OpenSSL on your machine.
