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]

      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-nextcloud-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-nextcloud-17.2-bullseye-amd64.iso
      8d38e563e4b8dc09060b4a25fb6786346d60c9eade7224e7a5f4ac36ec2051b1  turnkey-nextcloud-17.2-bullseye-amd64.iso

    $ sha512sum turnkey-nextcloud-17.2-bullseye-amd64.iso
      ccb14f08e07b84e42834d2cbfd6ff771e7d2c1a1252e59a1a45f74546fb388bd4ae53504d64a6e5d48edc720d10a2915c3e04aad5b6df8472d994d6fbc6eba7b  turnkey-nextcloud-17.2-bullseye-amd64.iso

   Note, you can compare hashes automatically::

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

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