      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-collabtive-16.0-buster-amd64-vmdk.zip.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-collabtive-16.0-buster-amd64-vmdk.zip
      c39448b7306d892fdc652121bf770b4b6354a2728e3a92a317cfd3b4bcb3ad5d  turnkey-collabtive-16.0-buster-amd64-vmdk.zip

    $ sha512sum turnkey-collabtive-16.0-buster-amd64-vmdk.zip

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-collabtive-16.0-buster-amd64-vmdk.zip.hash
      turnkey-collabtive-16.0-buster-amd64-vmdk.zip: OK

    $ sha512sum -c turnkey-collabtive-16.0-buster-amd64-vmdk.zip.hash
      turnkey-collabtive-16.0-buster-amd64-vmdk.zip: OK

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