Wireguard is a free and open-source software application and communication protocol that implements virtual private network (VPN) techniques to create secure point-to-point connections in routed or bridged configurations. It was designed to be simpler and easier to audit than other VPN protocols, such as OpenVPN and IPSec.

Wireguard uses a lightweight and fast cryptographic protocol that operates in the kernel space, making it efficient and easy to implement. It also uses modern cryptographic techniques, such as curve25519, ChaCha20, and Poly1305, to provide strong security for the VPN connection.

Wireguard has a number of benefits over other VPN protocols. For one, it is much simpler and easier to understand, making it easier to audit for security vulnerabilities. It is also much faster, as it operates in the kernel space and uses modern cryptographic techniques that are optimized for speed.

Wireguard is also designed to be easy to set up and use. It uses a simple configuration file, and the client and server can be easily configured using the command line. It also has support for various platforms, including Linux, Android, iOS, macOS, and Windows.

Overall, Wireguard is a promising new VPN protocol that offers strong security, simplicity, and performance. It is an excellent choice for those who want a fast and secure VPN connection.

The Future

Unfortunately, as privacy and security technology advances, so does the technology used to invade privacy and surveil individuals. The good news, however, is that people are already one step ahead and looking how to advane Wireguard to be futureproof. PQ-WireGuard is an implementation of the WireGuard protocol in the PQ (post-quantum) cryptography library. PQ-WireGuard combines the benefits of WireGuard with the added security of post-quantum cryptographic algorithms, which are resistant to quantum computers and considered to be more secure than traditional cryptographic algorithms.

WireGuard vs OpenVPN

Whether WireGuard is better than OpenVPN depends on the specific use case and requirements. Both WireGuard and OpenVPN are popular and widely used VPN protocols that offer different trade-offs in terms of security, speed, and ease of use.

WireGuard is a relatively new VPN protocol that was designed to be fast, simple, and secure. It uses state-of-the-art cryptography, has a minimal codebase, and is designed to be easily auditable and maintainable. WireGuard has been praised for its simplicity, speed, and security, and has been gaining popularity in recent years.

OpenVPN, on the other hand, is a more established VPN protocol that has been around for over two decades. It is known for its flexibility and versatility, and can be configured to meet a wide range of security and privacy requirements. OpenVPN is widely supported and has been thoroughly audited and tested, making it a popular choice for many VPN users.
