How to flash secure boot enabled chip and have flash encryption? Is this implemented?

risoul commented 1 year ago

I second that. My goal is using esptool-js to provide upgrades to my users, but I do not want show original code of the .bin

I solved flashing, however the .bin file is always displayed when you check resources with dev tools.

risoul commented 1 year ago

As i understand, you talk about .bin server side? then it is not encrypted?

I found this about encryption : https://www.motius.com/post/how-to-build-a-secure-iot-prototype-with-arduino-and-esp32 Using arduino to code then esp-idf to encrypt

But I do not know if it can be flashed with esptool-js

Hello, I would too like to ask about any plans for supporting flash encryption in esptool-js.

@mrninhvn , how do I run your fork? Can you host it on github? That would be great.

is anyone else getting "unsupported command error"?

You can build this example or modify esp-web-tool to use the enc-esptool-js module. I do a quick deloy here: https://mrninhvn.github.io/esptool-js/
