    $ gpg --verify turnkey-lighttpd-php-fastcgi-16.0-buster-amd64.iso.hash
      gpg: Signature made using RSA key ID A8B2EF4287819B03D3516CCA76231C20425E9772
      gpg: Good signature from "0"

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

    $ sha256sum turnkey-lighttpd-php-fastcgi-16.0-buster-amd64.iso
      e9e762320c7e925ec2deca751512c14e6348d9f2ba97f8c9e25a93ccb2aacd72  turnkey-lighttpd-php-fastcgi-16.0-buster-amd64.iso

    $ sha512sum turnkey-lighttpd-php-fastcgi-16.0-buster-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-lighttpd-php-fastcgi-16.0-buster-amd64.iso.hash
      turnkey-lighttpd-php-fastcgi-16.0-buster-amd64.iso: OK

    $ sha512sum -c turnkey-lighttpd-php-fastcgi-16.0-buster-amd64.iso.hash
      turnkey-lighttpd-php-fastcgi-16.0-buster-amd64.iso: OK
