    $ gpg --verify turnkey-nginx-php-fastcgi-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-nginx-php-fastcgi-17.0-bullseye-amd64.iso
      f77abe94688cceacdd145c5c2addda7259f620fece1872fbc52600fae31ccb02  turnkey-nginx-php-fastcgi-17.0-bullseye-amd64.iso

    $ sha512sum turnkey-nginx-php-fastcgi-17.0-bullseye-amd64.iso
      67b594136be94799e2fab81d1f8d93bc257a600cce45364bbeb5902d16e6cc802c0880bedbd8d673ab9962741002e3a5eac61600f7752bed239280bf7b815d91  turnkey-nginx-php-fastcgi-17.0-bullseye-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-nginx-php-fastcgi-17.0-bullseye-amd64.iso.hash
      turnkey-nginx-php-fastcgi-17.0-bullseye-amd64.iso: OK

    $ sha512sum -c turnkey-nginx-php-fastcgi-17.0-bullseye-amd64.iso.hash
      turnkey-nginx-php-fastcgi-17.0-bullseye-amd64.iso: OK
