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-nodejs-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-nodejs-18.0-bookworm-amd64.iso
      34328c4975e8032d85abd5f6a75c786d86dcd8e3c60b2ecea102154354984484  turnkey-nodejs-18.0-bookworm-amd64.iso

    $ sha512sum turnkey-nodejs-18.0-bookworm-amd64.iso
      549899c68c9dbc73d5884bd77aaeba93e3424c7eb4ed754b7bf1a839391da4a03e7857c9c60043b4b8a5b3f0d6a411586e4f28a334c3f8e4a3b357f652e1a475  turnkey-nodejs-18.0-bookworm-amd64.iso

   Note, you can compare hashes automatically::

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

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

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