      sub   rsa4096 2021-08-04 [S] [expires: 2041-07-30]
      
    $ gpg --verify turnkey-bookstack-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-bookstack-17.2-bullseye-amd64.iso
      6902984efdbfbcb939227d2ce720a7e6299794499c2fe599fdd9b4a5f03f2d6f  turnkey-bookstack-17.2-bullseye-amd64.iso

    $ sha512sum turnkey-bookstack-17.2-bullseye-amd64.iso

   Note, you can compare hashes automatically::

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

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

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