To ensure the image has not been corrupted in transmit or tampered with,
perform the following two steps to cryptographically verify image integrity:

1. Verify the authenticity of this file by checking that it is signed with our
   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-omeka-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-omeka-18.0-bookworm-amd64.iso
      d45f16fce19ba6f921748b2f5eefa046417a3e95aca5132acd6cc14b494f1121  turnkey-omeka-18.0-bookworm-amd64.iso

    $ sha512sum turnkey-omeka-18.0-bookworm-amd64.iso
      a10a3f74f7844d6d138dbc9ff4b0f8dd1a3d7763fe624647d3193c416ee04b24176ad8d14b887c04875f11ff667d045e55466d6e1d794215a84ea14ccdf52d42  turnkey-omeka-18.0-bookworm-amd64.iso

   Note, you can compare hashes automatically::

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

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

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