      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 turnkey-phplist-16.0-buster-amd64.iso.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 turnkey-phplist-16.0-buster-amd64.iso
      51dca5792e2deebb9ee4c956214d81356b7816e180d1358c9fd14e58b8aae9f7  turnkey-phplist-16.0-buster-amd64.iso

    $ sha512sum turnkey-phplist-16.0-buster-amd64.iso
