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-espocrm-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-espocrm-18.0-bookworm-amd64.iso
      e9dbfd6e04010b50cc6f2cd87b47a658b569edfb7a093e11d891264677dbf07d  turnkey-espocrm-18.0-bookworm-amd64.iso

    $ sha512sum turnkey-espocrm-18.0-bookworm-amd64.iso
      0677a2c5ae3f43f53ac54ede9ac784ddbd62d77239e747b1f867cda164f6c45d1be1bfaaec849dd90dadbfcd5e4f9c22e5dc615a870c326a7e35e2b86611f8a7  turnkey-espocrm-18.0-bookworm-amd64.iso

   Note, you can compare hashes automatically::

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

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