ESP32 Forum

I don't want an out-sider who have physical access to my esp32 able to read my uploaded firmware.
So,
I need to know, is the Flash encryption and Secure boot methods will protect my firmware from copying by an attacker who have physical access to my esp32.

Yes. That is one of the purposes of these methods (the other purpose is to prevent unauthorized firmware being loaded onto the device). For more details, see https://docs.espressif.com/projects/esp ... ption.html and https://docs.espressif.com/projects/esp ... -boot.html
