Secure Ethernet?

by jetforme on Wed Aug 04, 2021 3:26 am

Hi there. From what I've been able to gather, there's no secure Ethernet support, is that right? I just got these awesome PoE FeatherWings, and I really want to be able to send secure MQTT messages with it.

What would it take to add TLS support to the Ethernet library? Why is it so neglected?

TIA,
Rick

Hi Rick,

Correct - there's no secure Ethernet support in the Arduino Ethernet Library (https://github.com/arduino-libraries/Ethernet). Only the TCP/IP stack is supported. This is the same for the Adafruit CircuitPython support for the wiznet w5x ethernet chip.


What would it take to add TLS support to the Ethernet library?

It's difficult.. An SSL client would need to be implemented in software, the wiznet chip doesn't natively support SSL.
