   GPG release key:

    $ 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-torrentserver-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-torrentserver-18.0-bookworm-amd64.iso
      f3081afa3ed4a597202ef03efbcc0c2926ae062c836ec93c533d6d9b7a380322  turnkey-torrentserver-18.0-bookworm-amd64.iso

    $ sha512sum turnkey-torrentserver-18.0-bookworm-amd64.iso
      9bf4cf5ba3f8923a0c2bf9b79155146928dedb2694fad548b9b50f0577e9aa3eb7d7611db99f6c7fdce60487430f550dbec2cb2a7678e165d6d420144ef384a1  turnkey-torrentserver-18.0-bookworm-amd64.iso

   Note, you can compare hashes automatically::

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

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