Secure DFU Package Generation Debug Private Key

[WestCoastDaz]

I am following the readme for nrfutil on generating a package file for the secure DFU. I am using the debug version of the bootloader which comes with a predefined public key and I can't find the associated debug private key. Is it included or do I need to create my own in order to debug?

Thanks

The private key is not included, but was used to sign the included test images. This was to be 100 % sure that it would not used for signing FW images in production by any of our customers.

Generating your own key:

• nrfutil keys generate private.pem

Display a public key from your key file

• nrfutil keys display --key pk --format code private.pem > pk.c

So I am also trying to generate my own keys, is this all that needs to be ran in nrfutil to generate the keys you need for your secure boot-loader code via SDK 15.3 DFU?

RyanA Yes, that is all you need to generate keys for use in the boot-loader.
