   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-couchdb-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-couchdb-18.0-bookworm-amd64.iso
      cfe9e6e6133fdf55bd176c1aec7501dea1d54a1d8c2e0c599c1af69eda2e9872  turnkey-couchdb-18.0-bookworm-amd64.iso

    $ sha512sum turnkey-couchdb-18.0-bookworm-amd64.iso
      b24cf34bdd93f92323d2f8f78e05fda55656ab7b88fafa08fcd70eadadb867124e0d80e5474a27153262418da3a225816ff448fc1fa372df63ae6158c66c61fd  turnkey-couchdb-18.0-bookworm-amd64.iso

   Note, you can compare hashes automatically::

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

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