    $ curl https://raw.githubusercontent.com/turnkeylinux/common/18.x/keys/tkl-bookworm-images.asc | gpg --import
    $ gpg --list-keys --with-fingerprint release-bookworm-images@turnkeylinux.org
      pub   rsa4096 2023-05-22 [SC] [expires: 2043-05-17]
            2614 7592 087C 0EDE 4214  3B63 7761 DEBA BBCF BA7C
      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-lamp-18.1-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-lamp-18.1-bookworm-amd64.iso
      4c7bb2b563a7e37b64603fd8cf88bbc0cdbf9548399a9102d11e251406e5462d  turnkey-lamp-18.1-bookworm-amd64.iso

    $ sha512sum turnkey-lamp-18.1-bookworm-amd64.iso
      467169240c1d6be905a8de193748d4f8cd74ea9c9c4c56e12ac0491eb860b9ac53fa47fcaa8869a173dd98ac4c95827265fbb61d8b01e3bb35284e5cf3b807c3  turnkey-lamp-18.1-bookworm-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-lamp-18.1-bookworm-amd64.iso.hash
      turnkey-lamp-18.1-bookworm-amd64.iso: OK

    $ sha512sum -c turnkey-lamp-18.1-bookworm-amd64.iso.hash
      turnkey-lamp-18.1-bookworm-amd64.iso: OK
