ESP32 Arduino mbed TLS: using the SHA-256 algorithm

In this tutorial we will check how to generate the hash of a string using the SHA-256 algorithm on the Arduino core running on the ESP32, with the mbed TLS libraries. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.
