Advanced users • Re: Reading secure boot keys from the booting OS.

You don't acknowledge having seen or read Secure Boot configuration properties - https://www.raspberrypi.com/documentati ... properties in the official Raspberry Pi documentation, or the White Paper 'How to use Raspberry Pi Secure Boot' linked from there.

I've read the white paper, and about secureboot in general, which cover verification of the image by the firmware using the keys in the OTP.

I'm looking to do the reverse: i.e.identify the hardware based on the user public key baked into the OTP, so that documentation didn't help.

you can dump a sha256 of the pub key stored in the OTP with mailbox

Thank you. That confirmation and keyword set should be enough for me requirements.

Thank you James. You've helped eliminate Google from my problem completely.

This can be locked, as complete.
