"Non-nil means to check package signatures when installing.
More specifically the value can be:
- nil: package signatures are ignored.
- `allow-unsigned': install a package even if it is unsigned, but
if it is signed, we have the key for it, and OpenGPG is
installed, verify the signature.
- t: accept a package only if it comes with at least one verified signature.
- `all': same as t, except when the package has several signatures,
in which case we verify all the signatures.
This also applies to the \"archive-contents\" file that lists the
contents of the archive."
