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://raw.githubusercontent.com/turnkeylinux/common/master/keys/tkl-buster-images.asc | gpg --import
    $ gpg --list-keys --with-fingerprint release-buster-images@turnkeylinux.org
      pub   rsa4096 2020-02-05 [SC] [expires: 2040-01-31]
            A8B2 EF42 8781 9B03 D351  6CCA 7623 1C20 425E 9772
      uid           [ unknown] TurnKey GNU/Linux Buster Images (GPG signing key for TurnKey Linux Buster Images) <release-buster-images@turnkeylinux.org>
      sub   rsa4096 2020-02-05 [S] [expires: 2040-01-31]
      
    $ gpg --verify turnkey-owncloud-16.0-buster-amd64.iso.hash
      gpg: Signature made using RSA key ID A8B2EF4287819B03D3516CCA76231C20425E9772
      gpg: Good signature from "0"

2. Recalculate the image hash and make sure it matches your choice of hash below.

    $ sha256sum turnkey-owncloud-16.0-buster-amd64.iso
      89ff7692798e86aba71f604cdd7ef4e478858a0dffbd7c178bdeb6d10784f59a  turnkey-owncloud-16.0-buster-amd64.iso

    $ sha512sum turnkey-owncloud-16.0-buster-amd64.iso
      069525ae8d7819d8f229799504750da15a832a93c215c7eceb71ea1076b9785a04d4d9c14a803d1d954c48118c8b83dd4dd1669cec8d175039a450d5cbff7367  turnkey-owncloud-16.0-buster-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-owncloud-16.0-buster-amd64.iso.hash
      turnkey-owncloud-16.0-buster-amd64.iso: OK

    $ sha512sum -c turnkey-owncloud-16.0-buster-amd64.iso.hash
      turnkey-owncloud-16.0-buster-amd64.iso: OK

    Final note, when checking SHAs automatically, please ignore warning noting that some lines are improperly formatted.
