    $ 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-nginx-php-fastcgi-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-nginx-php-fastcgi-16.0-buster-amd64.iso
      a0eb5e3a3dada429ba3e81b7a3db8c556897d38bb4cd04a630eee66190b265c8  turnkey-nginx-php-fastcgi-16.0-buster-amd64.iso

    $ sha512sum turnkey-nginx-php-fastcgi-16.0-buster-amd64.iso
      bfb5e696577c499d30d70c167da76def5c1b937c6646dc7424d6b74db2455c82f2b8e2ef34e9d26b8d514878f860f55b8b65be55ee42cf5cda7420754b229f7a  turnkey-nginx-php-fastcgi-16.0-buster-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-nginx-php-fastcgi-16.0-buster-amd64.iso.hash
      turnkey-nginx-php-fastcgi-16.0-buster-amd64.iso: OK

    $ sha512sum -c turnkey-nginx-php-fastcgi-16.0-buster-amd64.iso.hash
      turnkey-nginx-php-fastcgi-16.0-buster-amd64.iso: OK

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