To ensure the image has not been corrupted in transmit or tampered with,
perform the following two steps to cryptographically verify image integrity:

1. Verify the authenticity of this file by checking that it is signed with our
   GPG release key:

    $ curl https://keybase.io/turnkeylinux/pgp_keys.asc | gpg --import
    $ gpg --list-keys --with-fingerprint release@turnkeylinux.com
      pub   2048R/A16EB94D 2008-08-15 [expires: 2023-08-12]

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

    $ gpg --verify turnkey-mattermost-15.2-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-mattermost-15.2-stretch-amd64-openstack.qcow2
      8b3369b5dfeea9345867c7fe9dde83ee757c1f86a51ffee1f2dfeb4290956ea0  turnkey-mattermost-15.2-stretch-amd64-openstack.qcow2

    $ sha512sum turnkey-mattermost-15.2-stretch-amd64-openstack.qcow2
      9912e886ce5302d797efd8e1a93a11d7a7291ccd8582c769dca69b3c4676131ef5853b615ff08897433b8b810e6e85a38fc13605a077b37f6763502bda51ce7b  turnkey-mattermost-15.2-stretch-amd64-openstack.qcow2

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-mattermost-15.2-stretch-amd64-openstack.qcow2.hash
      turnkey-mattermost-15.2-stretch-amd64-openstack.qcow2: OK

    $ sha512sum -c turnkey-mattermost-15.2-stretch-amd64-openstack.qcow2.hash
      turnkey-mattermost-15.2-stretch-amd64-openstack.qcow2: OK
