WireGuard® is an extremely simple yet fast and modern VPN that
utilizes state-of-the-art cryptography. With this, you can do a base and offline installation of OpenBSD
and, right at the beginning, set up a good VPN like Mullvad or IVPN for
total anonymity (Mullvad and IVPN officially support WireGuard).
