    11.4. Detached Signatures

        Some OpenPGP applications use so-called "detached signatures". For
        example, a program bundle may contain a file, and with it a second
        file that is a detached signature of the first file. These detached
        signatures are simply a Signature packet stored separately from the
        data for which they are a signature.
