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-mediaserver-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-mediaserver-18.1-bookworm-amd64.iso
      4a7423b1cb8d31d3ae56d2b16367f9e302e8ced9d2f81b807899de40de6de50c  turnkey-mediaserver-18.1-bookworm-amd64.iso

    $ sha512sum turnkey-mediaserver-18.1-bookworm-amd64.iso
      3ba265c11f5e67df40e78d234d3d6bf64ca109ac3b3666476507583f9a16041912799b13d767c22fc055cdae12069e2d3ec7ee38a2c53ba94b6dccf82cd35a1a  turnkey-mediaserver-18.1-bookworm-amd64.iso

   Note, you can compare hashes automatically::

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

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

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