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

    $ gpg --verify turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2.hash
      gpg: Signature made using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key <release@turnkeylinux.com>"

    For extra credit you can validate the key's authenticity at:

2. Recalculate the image hash and make sure it matches your choice of hash below.

    $ sha256sum turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2
      f9573b64d7dea76d353c08a4c4b6e2a7e18b436fab55e18f8c13f04a702ecea2  turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2

    $ sha512sum turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2
      cb552156cd23c7ef854d1ab0fb4d40a059f4955e4cc0173771fb97fee2dafbfd28c46360fe9abc101c117b01786006edef2ab760a026744eaa9525abeeab4ed4  turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2.hash
      turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2: OK

    $ sha512sum -c turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2.hash
      turnkey-domain-controller-15.0-stretch-amd64-xen.tar.bz2: OK
