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  | gpg --import
    $ gpg --list-keys --with-fingerprint release-bullseye-images@turnkeylinux.org
      pub   rsa4096 2021-08-04 [SC] [expires: 2041-07-30]
            E10F 6567 0C8E BE42 ED0C  3A49 CCA5 1174 468F 9073
      uid           [ unknown] TurnKey GNU/Linux Bullseye Images (GPG signing key for TurnKey Linux Bullseye Images) <release-bullseye-images@turnkeylinux.org>
      sub   rsa4096 2021-08-04 [S] [expires: 2041-07-30]
      
    $ gpg --verify turnkey-mattermost-17.2-bullseye-amd64.iso.hash
      gpg: Signature made using RSA key ID E10F65670C8EBE42ED0C3A49CCA51174468F9073
      gpg: Good signature from "0"

2. Recalculate the image hash and make sure it matches your choice of hash below.

    $ sha256sum turnkey-mattermost-17.2-bullseye-amd64.iso
      579e5b83ac548a6030850a63034fda760b075a3b42c4d3a1520e0cf9bdf49f6a  turnkey-mattermost-17.2-bullseye-amd64.iso

    $ sha512sum turnkey-mattermost-17.2-bullseye-amd64.iso
      658b0ea1c95b2b6dff60a8e845f6f27fbd3df7a7b4050004f9f400d550d7304383fd12e9b387258b2782b6139287d85d75e7bf2017b9e85746fe5dff1c0a2b9e  turnkey-mattermost-17.2-bullseye-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-mattermost-17.2-bullseye-amd64.iso.hash
      turnkey-mattermost-17.2-bullseye-amd64.iso: OK

    $ sha512sum -c turnkey-mattermost-17.2-bullseye-amd64.iso.hash
      turnkey-mattermost-17.2-bullseye-amd64.iso: OK

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