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-concrete5-15.1-stretch-amd64-openstack.qcow2.hash
      gpg: Signature made using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key <release@turnkeylinux.com>"

    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-concrete5-15.1-stretch-amd64-openstack.qcow2
      aa1a1618fe99dd7ddef747eb3dcbcbef9403579061042277867a84fdd9f82fda  turnkey-concrete5-15.1-stretch-amd64-openstack.qcow2

    $ sha512sum turnkey-concrete5-15.1-stretch-amd64-openstack.qcow2
      f94f071ffd34f4be524c5b0999ea55269b046a6adb2c6ff7dc61d8810e43069d89197cdd2d800aaa50db4522f9e841b0730d8e0cd1cc913fd574481cfe0fdea1  turnkey-concrete5-15.1-stretch-amd64-openstack.qcow2

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-concrete5-15.1-stretch-amd64-openstack.qcow2.hash
      turnkey-concrete5-15.1-stretch-amd64-openstack.qcow2: OK

    $ sha512sum -c turnkey-concrete5-15.1-stretch-amd64-openstack.qcow2.hash
      turnkey-concrete5-15.1-stretch-amd64-openstack.qcow2: OK
