What is ECC608 crypto chip accelerator used for in Arduino Uno Wifi rev2?

Question

Arduino Uno Wifi rev2 includes an ECC608 crypto accelerator chip.

Even their documentation states "As for the WiFi connection, that's made secure with the new ECC608 crypto chip accelerator."

My question is: how exactly the ECC608 is used? I'd like to see the sources the Arduino makes the "WiFi secure" with it.

The library for the chip is ArduinoECCX08. It is used by the ArduinoBearSSL library. The ArduinoBearSSL is used by the ArduinoIoTCloud library and Arduino_OAuth library. .

Thanks. So normally when using WiFiSSLClient (arduino.cc/en/Tutorial/WiFiNINAWiFiSSLClient), ECC608 is not used at all? – Daniel Dec 18 '19 at 13:48

for WiFiNINA, the esp32 firmware handles secure connection with IDF framework utilities. – Juraj Dec 18 '19 at 16:11
