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

    $ gpg --verify debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz.hash
      gpg: Signature made using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key <release@turnkeylinux.com>"

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

    $ sha256sum debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz
      d3a398431734bba93d78c55deb240968005a9ca8dcabe6a2a70b412e405b7e1b  debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz

    $ sha512sum debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz
      f11c513bfcd061d70ec4e9c8357e6e28f5a0e477feb2973db5711ad4958fdf32b2a5a12dcc7599dbad978cee37bb84ea611ac5498147f6118c330702f2e02ae8  debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz

   Note, you can compare hashes automatically::

    $ sha256sum -c debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz.hash
      debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz: OK

    $ sha512sum -c debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz.hash
      debian-9-turnkey-simplemachines_15.0-1_amd64.tar.gz: OK
