# GPG Keys
1.  Import the user private key: `gpg import gpg/users/albert/privkey.asc`
2.  Mark it as trusted:  `gpg --edit-key albert@sysctl.io`, then type `trust`, then `5`
3.  On each new machine, run `nix-shell -p ssh-to-pgp --run "ssh-to-pgp -i /etc/ssh/ssh_host_rsa_key -o HOSTNAME.asc"`
    * This will output the identifier you add to `.sops.yaml`
    * Move `HOSTNAME.asc` to `keys/hosts/` and upload to git and rename accordingly.

# Secrets
1.  To edit a file: cd to `/path/to/nix-files/` and run:
    * `nix-shell -p sops --run "sops secrets/secret_file.yml"`
    * New shell alias: `sops secrets/secret_file.yml`
2.  When you add a new machine, you must update the secrets files encryption.  
    * Run `sops-update secrets/secrets.yaml` and commit the change.

# Lanzaboote / SecureBoot
*  Instructions here - [Link](https://git.sysctl.io/Mirrors/lanzaboote/src/branch/master/docs/QUICK_START.md)
1. Create your keys: `sbctl create-keys`
2.  Verify your machine is ready for SecureBoot:  `sbctl verify` - Everything except `*-bzImage.efi` are signed  
3.  Enter Secureboot Setup mode in your EFI Settings on the motherboard (F10)
    * Security -> SecureBoot -> Set to Enabled and "Reset to Setup Mode" and exit
4.  Enroll the keys:  `sbctl enroll-keys --microsoft` 
    * If you wish, you can select `--tpm-eventlog`, but checksums will change later (ie, at a kernel rebuild)
5.  Reboot and verify you are activated:  `bootctl status`
