    $ gpg --verify turnkey-limesurvey-17.0-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-limesurvey-17.0-bullseye-amd64.iso
      2ad80c5693cd6737f1cbf317ce88dc38f9bb03ba3071940fab00a79a79e51371  turnkey-limesurvey-17.0-bullseye-amd64.iso

    $ sha512sum turnkey-limesurvey-17.0-bullseye-amd64.iso
