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

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?

Vidar, I had a feeling the private key wasn't included for the reason you outlined. Thanks for confirming.

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
