    $ gpg --verify turnkey-web2py-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-web2py-17.1-bullseye-amd64.iso
      31e804781fb4d1120404d882a1a3b004247776a4316bd7736f4fffa84ffd8b89  turnkey-web2py-17.1-bullseye-amd64.iso

    $ sha512sum turnkey-web2py-17.1-bullseye-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-web2py-17.1-bullseye-amd64.iso.hash
      turnkey-web2py-17.1-bullseye-amd64.iso: OK

    $ sha512sum -c turnkey-web2py-17.1-bullseye-amd64.iso.hash
      turnkey-web2py-17.1-bullseye-amd64.iso: OK
