      uid   Turnkey Linux Release Key <release@turnkeylinux.com>

    $ gpg --verify turnkey-concrete5-15.1-stretch-amd64-vmdk.zip.hash
      gpg: Signature made using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key <release@turnkeylinux.com>"

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-concrete5-15.1-stretch-amd64-vmdk.zip.hash
      turnkey-concrete5-15.1-stretch-amd64-vmdk.zip: OK

    $ sha512sum -c turnkey-concrete5-15.1-stretch-amd64-vmdk.zip.hash
