Have desire to do " hands on , trial, test run " A tutorial similar to randomnerd tutorial " ESP32/ESP8266 with HTTPS and SSL/TLS" with a little more detail on external hardware spec and hook up , code, examples with step by step server access ,server response , that I can trial. This would be a beginners exercise . If that content already exists then just provide the location . Been exposed to a little of the algebra ( Public Key Cryptography- the math ) in grad school , have time now to take a walk thru the mechanics and methods created in computer science - thanks
