-Espressif's ESP32-S2, ESP32-S3, ESP32-C3 and ESP32-C6 MCU have a built-in Digital Signature (DS) Peripheral, which provides hardware acceleration for RSA signature.

 This example connects to the broker test.mosquitto.org using ssl transport with client certificate(RSA) and as a demonstration subscribes/unsubscribes and sends a message on certain topic.The RSA signature operation required in the ssl connection is performed with help of the Digital Signature (DS) peripheral.
 (Please note that the public broker is maintained by the community so may not be always available, for details please visit http://test.mosquitto.org)
