This article covers how wireguard works on the Digitalocean platform running Ubuntu 22.04 (Jammy Jellyfish). In fact, WireGuard's encryption relies on public and private keys for peers to establish an encrypted tunnel between themselves. Each version of WireGuard uses a specific cryptographic cipher suite to ensure simplicity, security, and compatibility with peers.
Here, you will learn how to route the peer's Internet traffic through the WireGuard server in a gateway configuration, in addition to using the VPN for an encrypted peer-to-peer tunnel.
WireGuard vs OpenVPN , Which is better?
- WireGuard offers a more reliable connection for mobile users than OpenVPN because it handles network changes better.
- OpenVPN adds a data overhead of up to 20%, whereas WireGuard uses just 4% more data (compared with not using a VPN).
- VPN services need to include mitigations to ensure user privacy when using WireGuard.
