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

    $ gpg --verify turnkey-concrete5-15.0-stretch-amd64-openstack.qcow2.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-concrete5-15.0-stretch-amd64-openstack.qcow2
      1aefc344ae9cb188cfe50f494454f6e17cef2deb5cd04d693e352c1441e96ffb  turnkey-concrete5-15.0-stretch-amd64-openstack.qcow2

    $ sha512sum turnkey-concrete5-15.0-stretch-amd64-openstack.qcow2
      44369bbc0ba837c30a285e6a6074738828750cfd79daa18846a11fdef8adb1d7818f36890965c635bdad35d3658e7d847a0a36bbea3975c46ccbe55661bfe519  turnkey-concrete5-15.0-stretch-amd64-openstack.qcow2

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-concrete5-15.0-stretch-amd64-openstack.qcow2.hash
      turnkey-concrete5-15.0-stretch-amd64-openstack.qcow2: OK

    $ sha512sum -c turnkey-concrete5-15.0-stretch-amd64-openstack.qcow2.hash
      turnkey-concrete5-15.0-stretch-amd64-openstack.qcow2: OK
