      sub   rsa4096 2023-05-22 [S] [expires: 2043-05-17]
      
    $ gpg --verify turnkey-lighttpd-php-fastcgi-18.0-bookworm-amd64.iso.hash
      gpg: Signature made using RSA key ID 26147592087C0EDE42143B637761DEBABBCFBA7C
      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-18.0-bookworm-amd64.iso
      f870eb72467f6e199766f7331f4bced7a1a71d2e9ad7ea8a872b3db6da6f3d93  turnkey-lighttpd-php-fastcgi-18.0-bookworm-amd64.iso

    $ sha512sum turnkey-lighttpd-php-fastcgi-18.0-bookworm-amd64.iso
      0f25c0e07863b3dc44bf298125a88b06de95c67e262b5b46fa7fb0836cad86c9f27d7d47f56d2bfc7ffc1307dd86373adf3b1dccdba23b09bc3e6992764e7da7  turnkey-lighttpd-php-fastcgi-18.0-bookworm-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-lighttpd-php-fastcgi-18.0-bookworm-amd64.iso.hash
      turnkey-lighttpd-php-fastcgi-18.0-bookworm-amd64.iso: OK

    $ sha512sum -c turnkey-lighttpd-php-fastcgi-18.0-bookworm-amd64.iso.hash
      turnkey-lighttpd-php-fastcgi-18.0-bookworm-amd64.iso: OK
