What you’re looking for is a revocation key. You can generate one in GPG at the same time that you generate your identity key. The method of securing it is up to you. In your example, a simple way would be to encrypt it with the 5 sequential keys. Or you could break the revocation key up into K parts with Shamir’s secret sharing algorithm.
This example assumes that you’re using existing Web of Trust PKI to manage your public keys: https://stackoverflow.com/questions/59664526/how-the-correct-way-to-revoke-gpg-on-key-server#62644875
As an emacs user, I use
M-x man
. All my standard keybindings make finding what I need very easy.Of course, it’s not so fast if you aren’t already in emacs.
