   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-silverstripe-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-silverstripe-16.0-buster-amd64.iso
      96a67a3879db8a461bc0cf849f3d41e9996202e8d03e738adcda0536373d233b  turnkey-silverstripe-16.0-buster-amd64.iso

    $ sha512sum turnkey-silverstripe-16.0-buster-amd64.iso
      be1d9c60fbf0af412d468f05a1d48bf5fa6b010dd566c9ee0283adce8c52c2e80fdabd92aeb7e3c7c7d939be1235c5564c9c9152aaea02cd944fbddc26fd1abe  turnkey-silverstripe-16.0-buster-amd64.iso

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

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