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

    $ gpg --verify turnkey-observium-15.1-stretch-amd64-openstack.qcow2.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 turnkey-observium-15.1-stretch-amd64-openstack.qcow2
      2f30d7ae81a4754ec78e554b1dec4e0b1fa0ccecbf2cf5f2a2a36011959817f1  turnkey-observium-15.1-stretch-amd64-openstack.qcow2

    $ sha512sum turnkey-observium-15.1-stretch-amd64-openstack.qcow2
      fb4dd9917c027a9ac2d66efc422569f265fd938ca707d6e1bc6b3e0dcb54cc560d66efaf0129cdf8442a0c4618012240420eeac9317023a0bd6c796c6c0b99b8  turnkey-observium-15.1-stretch-amd64-openstack.qcow2

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-observium-15.1-stretch-amd64-openstack.qcow2.hash
      turnkey-observium-15.1-stretch-amd64-openstack.qcow2: OK

    $ sha512sum -c turnkey-observium-15.1-stretch-amd64-openstack.qcow2.hash
