By default, agenix uses `~/.ssh/id_ed25519.pub` or `~/.ssh/id_rsa.pub` as the encryption key. `agenix` will encrypt the file with all the public keys we defined in `secrets.nix`,
If you want to use a custom key located at `/path/to/key.pub` for encryption, pass `--identity /path/to/key`. so all the users and systems defined in `secrets.nix` can decrypt it with their private keys.
