OTA update authenticity required

[JainamShah]

Hello,
I am working on the OTA-based firmware update... I want to authenticate the sender at the ESP32 end. Do we have any examples related to that?
Kindly help me with this...

Examples at https://github.com/espressif/esp-idf/tr ... system/ota should help here, presuming you have your firmware image hosted on HTTPS server. Additionally, blog post at https://blog.espressif.com/ota-updates- ... 5438e30c12 has further details (regarding server authentication) that you may find useful.

Please do let us know if you have any further questions.
