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-gameserver-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-gameserver-18.1-bookworm-amd64.iso
      03b9cb56773e2924b9c1a7e11a1559515cdce35bf2c5c0df8bd59450e29c93cc  turnkey-gameserver-18.1-bookworm-amd64.iso

    $ sha512sum turnkey-gameserver-18.1-bookworm-amd64.iso
      c24093f4d240ed88a630fd234bb689f859d5770dfeda43da0ff7de4f363798e8767ee591f367a0441ef60a1975037e543d5b98ade4685a4d53cf64e4ed4e1616  turnkey-gameserver-18.1-bookworm-amd64.iso

   Note, you can compare hashes automatically::

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

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

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