      sub   rsa4096 2021-08-04 [S] [expires: 2041-07-30]
      
    $ gpg --verify turnkey-concrete-cms-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-concrete-cms-17.1-bullseye-amd64.iso
      4bc7275c9087e12fc47eba9db3ed448c40be50d15b25919d16330293344deac5  turnkey-concrete-cms-17.1-bullseye-amd64.iso

    $ sha512sum turnkey-concrete-cms-17.1-bullseye-amd64.iso

   Note, you can compare hashes automatically::

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

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