    $ gpg --verify turnkey-openvpn-18.0-bookworm-amd64.iso.hash
      gpg: Signature made using RSA key ID 26147592087C0EDE42143B637761DEBABBCFBA7C
      gpg: Good signature from "0"

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

    $ sha256sum turnkey-openvpn-18.0-bookworm-amd64.iso
      ab39b7a6471475ed38fa61f6cd2e78ed0913578a79a07030270ba01e3f682990  turnkey-openvpn-18.0-bookworm-amd64.iso
