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 debian-11-turnkey-observium_17.1-1_amd64.tar.gz.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 debian-11-turnkey-observium_17.1-1_amd64.tar.gz
      2559c5eb9527b3dd411a72069fa41eb4568094b4dafad0dc7060a034dd562d16  debian-11-turnkey-observium_17.1-1_amd64.tar.gz

    $ sha512sum debian-11-turnkey-observium_17.1-1_amd64.tar.gz
      6a01e71f9806db0c2fcb2a91ecba25dfa707c16afb959952ba50abc7e0bc3d1ca34a9e444d85614da9db6214eaf8eeba3f01f943b43236c07fa3110c27f04358  debian-11-turnkey-observium_17.1-1_amd64.tar.gz

   Note, you can compare hashes automatically::

    $ sha256sum -c debian-11-turnkey-observium_17.1-1_amd64.tar.gz.hash
      debian-11-turnkey-observium_17.1-1_amd64.tar.gz: OK

    $ sha512sum -c debian-11-turnkey-observium_17.1-1_amd64.tar.gz.hash
      debian-11-turnkey-observium_17.1-1_amd64.tar.gz: OK

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