    $ gpg --verify turnkey-silverstripe-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-silverstripe-17.1-bullseye-amd64.iso
      0e72bce62c21029f0691502925c7ae7bd4d70c539dfb83bdf54a41048edb3f6b  turnkey-silverstripe-17.1-bullseye-amd64.iso
