WireGuard is a free and open-source virtual private network (VPN) protocol that was designed with the goals of simplicity, speed, and security in mind. It was created by Jason A. Donenfeld in 2015 and has gained popularity due to its lightweight and efficient design.
Unlike traditional VPN protocols, such as OpenVPN and IPSec, which are based on complex cryptographic algorithms and protocols, WireGuard uses modern cryptographic techniques such as the Noise protocol framework and ChaCha20 for encryption. This allows WireGuard to provide faster and more efficient performance while maintaining a high level of security.
WireGuard is also designed to be easy to set up and configure, with a small codebase that is easy to audit for security vulnerabilities. It has been integrated into the Linux kernel since version 5.6, making it available on many popular operating systems.
WireGuard uses a unique approach to establish and maintain VPN connections called “cryptokey routing”. This involves assigning a public key to each client and server and using these keys to encrypt and decrypt network traffic. This approach eliminates the need for complex certificate authority systems and simplifies the overall setup and management of the VPN.
WireGuard thus offers a modern, efficient, and secure VPN protocol that is well-suited for a variety of use cases, including remote access, site-to-site connections, and mobile devices.
How to use WireGuard VPN:
1. Download and install WireGuard Apps on Play Store or etc.
2. Create your account and SSH VPN website and you can also fill in SNI/Bug hostname there
3. Download the configuration from the above step
4. Import the configuration to WireGuard apps
5. Connect and Enjoy.
