Hash: SHA512

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 debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz.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 debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz
      af8d3b3eb18c404f99c23e40c39514b9320004d45bd1cbbcf6fbff5d9bb51c8e  debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz

    $ sha512sum debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz
      1bb115c52a86b4c3efb4e996652af5bc59720e342b521aab8fade1ed0cca9920acd97f474dca0418097bd29d39bb39360abddc1ce63e7a3a148c1e36d57d6714  debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz

   Note, you can compare hashes automatically::

    $ sha256sum -c debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz.hash
      debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz: OK

    $ sha512sum -c debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz.hash
      debian-12-turnkey-jenkins_18.0-1_amd64.tar.gz: OK

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