I'm trying to connect my ESP8266 modules to a MQTT server and I want to practice using JWT. Does anybody have any experience doing this or can point me to some helpful links? I see some examples with SHA256 but I want to implement a private/public key pair with RS256.
I am speculating using Google Cloud Core IoT JWT, ArduinoJSON, and the PubSubClient libraries.
Thank you! Looking forward to some helpful guidance!
