EthernetClient with certificate support

[Step73]

Due to the limited "horse-power" of standard Arduino boards, I migrated to STM32-based (Nucleo 429ZI) with the hope I can use certificates to connect to AWS services. For example, I found this for a WiFi Arduino: https://github.com/Ameba8195/Arduino/bl ... _basic.ino.

I found https://github.com/stm32duino/STM32Ethernet/issues/14 issue but honestly I don't understand if the code was already merged. Looking at the code of EthernetClient I still don't find the setRootCA() and setClientCertificate() functions.

Would you mind to clarify me the state of this feature? It's a pity we cannot use secure connections with plenty of hardware resources!
Thanks in advance

The STM32Ethernet library does not have the SSL support, as mentioned in the PR you need to use an other one to get the support:

I've never try it.
