WireGuard is a fast and modern VPN protocol that uses advanced cryptography. It is simpler and more flexible than IPsec and OpenVPN, making it suitable for many uses. Is the latest addition to the VPN protocol list.

WireGuard, an advanced VPN protocol, not only stands out with its extremely fast speed and high security, but also has the ability to operate independently as a self-sufficient VPN system. Known as the fastest VPN protocol available today, WireGuard outperforms IPsec/IKEv2 and OpenVPN in providing the optimal combination of speed and performance.
WireGuard is built as a lean tunneling solution, using just under 4,000 lines of code, compared to OpenVPN's 100,000 lines. Concise source code not only makes deployment and management easier, but also delivers impressive performance and speed, while minimizing the risk of security vulnerabilities.
WireGuard's goal is to replace or improve current solutions such as IKEv2/IPSec and OpenVPN. By taking advantage of the best advantages from other protocols, WireGuard promises to bring a more powerful, secure and efficient VPN experience to users.
How does the WireGuard protocol work?

WireGuard uses an advanced approach in protecting data in transit by incorporating advanced encryption operations. This protocol leverages a routing cryptography called "cryptographic key routing," which works by associating public keys with an explicitly used list of IP addresses, creating a secure tunnel.
The public key is used for peer authentication between devices. This means that the key can be transmitted through any means outside the main communication channel, similar to how you can share an SSH public key with friends to access a shell server.
When deploying WireGuard, the security configurations between the client and the server are predetermined, making the connection process faster because there is no need to establish or re-establish a connection to the server. This explains why WireGuard connections do not take significant time.
Everything you need is your key and the server's key. The key exchange in the WireGuard protocol is based on NoiseIK, a unique key exchange process. These processes are performed automatically, you just need to select the desired server and the application will handle the rest flexibly and conveniently.
