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-jenkins-15.3-stretch-amd64.iso.hash
      gpg: Signature made using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key <release@turnkeylinux.com>"

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-jenkins-15.3-stretch-amd64.iso.hash
      turnkey-jenkins-15.3-stretch-amd64.iso: OK

    $ sha512sum -c turnkey-jenkins-15.3-stretch-amd64.iso.hash
