# 🔒 Lanzaboote / SecureBoot
*  Instructions here - [Link](https://git.sysctl.io/Mirrors/lanzaboote/src/branch/master/docs/QUICK_START.md)

## 🔒 Generic Instructions:
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`

## 💻 Framework Specific:
1.  Change boot import from `boot.nix` to `secureboot.nix` in `./nixos/hosts/<hostname>/default.nix`
4.  Run `rebuild-host` to switch from `boot.nix` to `secureboot.nix`
2.  Reboot into EUFI and set SecureBoot settings to:
    * Enforce Secure Boot - Enabled
    * Erase all Secure Boot Settings - Enabled
    * Restore Secure Boot to Factory Settings - Disabled
3.  Save and reboot
4.  Run `sudo sbctl create-keys`
5.  Run `sudo sbctl enroll-keys`
6.  Reboot and verify with `bootctl status`

# 🗝️ Manual:  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.  Run `nix-develop` in `/etc/nixos/git` to import new keys
2.  To edit a file: `sops secrets/file.yml"`
3.  When you add a new machine, you must update the secrets files encryption. 
    * Ensure `.sops.yaml` has the updated fingerprint and file mappings.
    * Run `sops updatekeys secrets/file.yaml` and commit the change.

# ℹ️  Troubleshooting
1.  To troubleshoot disko issues, this command can come in handy:
```
 nix eval .#nixosConfigurations.`hostname`.config.disko.devices._config
```
