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-collabtive-16.1-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-16.1-buster-amd64.ova
      879942d3a11ba3cea9a4ab54b2b60e14fd691ed005d8c6ce766fb32fb98fc95a  turnkey-collabtive-16.1-buster-amd64.ova

    $ sha512sum turnkey-collabtive-16.1-buster-amd64.ova
      81b36a80f76b1745b93cf7c495bba4dcb83bf28de102e66501952f554bfeec3b20afa6d31e4c7ad3085e6db19995283b16bd4191dc4ac1ee06ba40f9b103d0ee  turnkey-collabtive-16.1-buster-amd64.ova

      turnkey-collabtive-16.1-buster-amd64.ova: OK

    $ sha512sum -c turnkey-collabtive-16.1-buster-amd64.ova.hash
      turnkey-collabtive-16.1-buster-amd64.ova: OK
