Using Flash Encryption

Postby Widgetman » Tue Feb 13, 2018 10:57 pm

All,
Is there a good example on how to use the flash encryption scheme for applications. I would like to develop an app using this part and maintain encrypting the image outside of the part so that it is only decrypted inside and run. I would need to update it OTA if possible using wifi. Any thoughts or suggestions would be appreciated.

Hi Widgetman,

Did you see the section on flash encryption in the documentation?
http://esp-idf.readthedocs.io/en/latest ... ption.html

This explains how to have your application encrypted in the ESP32 flash. OTA updating is supported when flash encryption is in use.
