      uid           [ unknown] TurnKey GNU/Linux Bookworm Images (GPG signing key for TurnKey Linux Bookworm Images) <release-bookworm-images@turnkeylinux.org>
      sub   rsa4096 2023-05-22 [S] [expires: 2043-05-17]
      
    $ gpg --verify turnkey-zoneminder-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-zoneminder-18.0-bookworm-amd64.iso
      f17f9e756a082b991685e3e82713a7e94e1d0242dcec83b2c677a213334071a5  turnkey-zoneminder-18.0-bookworm-amd64.iso

    $ sha512sum turnkey-zoneminder-18.0-bookworm-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-zoneminder-18.0-bookworm-amd64.iso.hash
      turnkey-zoneminder-18.0-bookworm-amd64.iso: OK

    $ sha512sum -c turnkey-zoneminder-18.0-bookworm-amd64.iso.hash
      turnkey-zoneminder-18.0-bookworm-amd64.iso: OK
