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 https://raw.githubusercontent.com/turnkeylinux/common/master/keys/tkl-buster-images.asc | gpg --import
    $ gpg --list-keys --with-fingerprint release-buster-images@turnkeylinux.org
      pub   rsa4096 2020-02-05 [SC] [expires: 2040-01-31]
            A8B2 EF42 8781 9B03 D351  6CCA 7623 1C20 425E 9772
      uid           [ unknown] TurnKey GNU/Linux Buster Images (GPG signing key for TurnKey Linux Buster Images) <release-buster-images@turnkeylinux.org>
      sub   rsa4096 2020-02-05 [S] [expires: 2040-01-31]
      
    $ gpg --verify debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz.hash
      gpg: Signature made using RSA key ID A8B2EF4287819B03D3516CCA76231C20425E9772
      gpg: Good signature from "0"

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

    $ sha256sum debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz
      7ace39a8d778caba3e8eba831b0ad9ba71515fbf9c1022876cf5620975cf0d2b  debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz

    $ sha512sum debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz
      08bdad1906f4f4a132a77820764c3ac38cc7296eaba8b1b634749109d670c364521e7e279b796878c1f6f4dde4346211a12e0a40bf757bed5e7925ec8aeb0376  debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz

   Note, you can compare hashes automatically::

    $ sha256sum -c debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz.hash
      debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz: OK

    $ sha512sum -c debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz.hash
      debian-10-turnkey-concrete5_16.1-1_amd64.tar.gz: OK

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