# 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 `sudo nix-shell -p ssh-to-pgp --run "ssh-to-pgp -i /etc/ssh/ssh_host_rsa_key -o /etc/nixos/git/keys/hosts/$(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 `cd /etc/nixos/git; nix-shell; 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`
