      uid           [ unknown] TurnKey GNU/Linux Bullseye Images (GPG signing key for TurnKey Linux Bullseye Images) <release-bullseye-images@turnkeylinux.org>
      sub   rsa4096 2021-08-04 [S] [expires: 2041-07-30]
      
    $ gpg --verify turnkey-drupal7-17.1-bullseye-amd64.iso.hash
      gpg: Signature made using RSA key ID E10F65670C8EBE42ED0C3A49CCA51174468F9073
      gpg: Good signature from "0"

2. Recalculate the image hash and make sure it matches your choice of hash below.

    $ sha256sum turnkey-drupal7-17.1-bullseye-amd64.iso
      1f1745bda6b1b02b9b35afe190f3d0233cf4f23976e50f0428ea3e320eab545a  turnkey-drupal7-17.1-bullseye-amd64.iso

    $ sha512sum turnkey-drupal7-17.1-bullseye-amd64.iso
      115eb1a823182b2717dd9f69f973af4668d96309dbe97d7fe07ac9d409ee8e4632a2b23f786a97b29604f3c505aeef959ff13b739db06eea466db693ffb8bdd1  turnkey-drupal7-17.1-bullseye-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-drupal7-17.1-bullseye-amd64.iso.hash
      turnkey-drupal7-17.1-bullseye-amd64.iso: OK

    $ sha512sum -c turnkey-drupal7-17.1-bullseye-amd64.iso.hash
      turnkey-drupal7-17.1-bullseye-amd64.iso: OK

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