Hash: SHA512

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-rails-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-rails-16.0-buster-amd64-vmdk.zip
      d403091bb49714587f250c315b2a9d22fdf2f2d2dcf92ce0dad894a3dcfe04ae  turnkey-rails-16.0-buster-amd64-vmdk.zip

    $ sha512sum turnkey-rails-16.0-buster-amd64-vmdk.zip
      04a891fb7b3bcde526e30f4d7ff42392bafd33a0ec9c15026a801755a62ce64d047cbdcaccd0a898dcdad426a8aa432d635154ab21ea5598e943f458e6309c28  turnkey-rails-16.0-buster-amd64-vmdk.zip

   Note, you can compare hashes automatically::

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

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

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