Name
nix key generate-secret
- generate a secret key for signing store paths
Synopsis
nix key generate-secret
[option...]
Examples
-
Generate a new secret key:
# nix key generate-secret --key-name cache.example.org-1 > ./secret-key
We can then use this key to sign the closure of the Hello package:
# nix build nixpkgs#hello # nix store sign --key-file ./secret-key --recursive ./result
Finally, we can verify the store paths using the corresponding public key:
# nix store verify --trusted-public-keys $(nix key convert-secret-to-public < ./secret-key) ./result
Description
This command generates a new Ed25519 secret key for signing store
paths and prints it on standard output. Use nix key convert-secret-to-public
to get the corresponding public key for
verifying signed store paths.
The mandatory argument --key-name
specifies a key name (such as
cache.example.org-1
). It is used to look up keys on the client when
it verifies signatures. It can be anything, but it’s suggested to use
the host name of your cache (e.g. cache.example.org
) with a suffix
denoting the number of the key (to be incremented every time you need
to revoke a key).
Format
Both secret and public keys are represented as the key name followed by a base-64 encoding of the Ed25519 key data, e.g.
cache.example.org-0:E7lAO+MsPwTFfPXsdPtW8GKui/5ho4KQHVcAGnX+Tti1V4dUxoVoqLyWJ4YESuZJwQ67GVIksDt47og+tPVUZw==
