   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-rails-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-rails-18.1-bookworm-amd64.iso
      75159b058bdcf8650cc18bb394d518e1d421e2ca5484474435b3119a0a41b3b6  turnkey-rails-18.1-bookworm-amd64.iso

    $ sha512sum turnkey-rails-18.1-bookworm-amd64.iso
      795f55b1041cc0c8465a81d8c1cd589a0889cc91ca99d3e4c36fd530fdf1518a84e2a4a964a54ac37a5e4b124e54104f4c31a1019e9b75246b3b30eef89999fd  turnkey-rails-18.1-bookworm-amd64.iso

   Note, you can compare hashes automatically::

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

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

    Final note, when checking SHAs automatically, please ignore warning noting that some lines are improperly formatted.
