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/19.x/keys/tkl-trixie-images.asc | gpg --import
    $ gpg --list-keys --with-fingerprint release-trixie-images@turnkeylinux.org
      pub   rsa4096 2025-10-07 [SC] [expires: 2045-10-02]
            DEE9 0D99 70AE 35D5 5B7C  6C2D C6D2 54B7 6A9D 9430
      uid           [ unknown] TurnKey GNU/Linux Trixie Images (GPG signing key for TurnKey Linux Trixie Images) <release-trixie-images@turnkeylinux.org>
      sub   rsa4096 2025-10-07 [S] [expires: 2045-10-02]
      
    $ gpg --verify debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz.hash
      gpg: Signature made using RSA key ID DEE90D9970AE35D55B7C6C2DC6D254B76A9D9430
      gpg: Good signature from "0"

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

    $ sha256sum debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz
      4e3eaa52a78ded285532d2cbbabd3d89f4301472aefaef066d866d1bf6f0f2ab  debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz

    $ sha512sum debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz
      de2cec58ad519fd5a507acf6b9adfbd9f165a96c653ab1f64d7cd1e905235020cb9ca0a81d3149f8e9f89f67beb237ec1d69a3cd8cf5caac90d6f6416c4ce8e9  debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz

   Note, you can compare hashes automatically::

    $ sha256sum -c debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz.hash
      debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz: OK

    $ sha512sum -c debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz.hash
      debian-13-turnkey-concrete-cms_19.0-1_amd64.tar.gz: OK

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