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-keyWe 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 ./resultFinally, 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==
