      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.ova.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.ova
      c06ba14993329081679a6d395f20c98f074554d2e2c942e875821496764d940b  turnkey-collabtive-16.0-buster-amd64.ova

    $ sha512sum turnkey-collabtive-16.0-buster-amd64.ova

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

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