+Use the specific @var{file}s as the public/private key pair used to sign
+the store items being published.

+The files must correspond to the same key pair (the private key is used
+for signing and the public key is merely advertised in the signature
+metadata).  They must contain keys in the canonical s-expression format
+as produced by @command{guix archive --generate-key} (@pxref{Invoking

+@file{/etc/guix/signing-key.sec} are used.
