Thanks, Michael. Can we sign in the separate state on special server for example? Looks like we can work with public key only in this step.

Why do we need to have private key for adding step? In documentation it is not very clear for me. You need to sign with private key and keep it secret and local and verify it during booting with public key. Private key is not distributed with the image Michael Thanks a lot.
