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-limesurvey-17.1-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-limesurvey-17.1-bullseye-amd64.iso
      fd42a1aec2c8dd1981363eda5249221a3f4a786ead1c79e4d1d58f5024dfff4a  turnkey-limesurvey-17.1-bullseye-amd64.iso

    $ sha512sum turnkey-limesurvey-17.1-bullseye-amd64.iso
      6c0f38f6b5960460c70fbecf17fea7964dcd6ef3d7fe6b6f80761f0aee6832ad86e1c7b75d9c7ef1833f22ae351ad188a38c1c050bc8a227e21dd6bd0fc605c7  turnkey-limesurvey-17.1-bullseye-amd64.iso

   Note, you can compare hashes automatically::

    $ sha256sum -c turnkey-limesurvey-17.1-bullseye-amd64.iso.hash
      turnkey-limesurvey-17.1-bullseye-amd64.iso: OK

    $ sha512sum -c turnkey-limesurvey-17.1-bullseye-amd64.iso.hash
      turnkey-limesurvey-17.1-bullseye-amd64.iso: OK

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