WireGuard: Fast & Modern VPNs
A lightweight, high-performance VPN utilizing state-of-the-art cryptography, designed for general-purpose use
What is WireGuard?
WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike.
Key features of WireGuard include:
- Simplicity - uses only around 4,000 lines of code, compared to hundreds of thousands in other VPNs
- Speed - Leverages state-of-the-art cryptography like Curve25519, ChaCha20, Poly1305, etc. Benchmarking has shown it to be much faster than both IPSec and OpenVPN
- Ease of configuration - The config file uses simple keywords and does not require setting up certificates or private keys
- Security - Relies on Noise protocol framework and formally verified cryptography like Curve25519
- Cross-platform - Available for Linux, Windows, macOS, iOS, Android and BSD with userspace client and kernel driver implementations
Some use cases of WireGuard include VPN connections for companies, remote access VPNs for mobile devices and secure networking between data centers. Its versatility, performance and ease of use makes WireGuard a suitable choice for most VPN deployments.
