How to install Wireguard on CentOS 8

In this tutorial, we are going to learn how to install Wireguard VPN on CentOS 8.

Wireguard is a communication protocol that is free and open-source software that implements encrypted virtual private networks(VPN) and was designed with some goals, to provide ease of use, high-speed performance, and low attack space.

Wireguard aims for better performance and more power than IPsec and OpenVPN. Wireguard protocol passes traffic over UDP. Let us define all these terms we have used so far. It utilizes state-of-the-art cryptography.

Virtual Private Network (VPN)- A VPN is an encrypted connection over the internet from a device to a network. The encrypted connection ensures that data is safely transmitted. It prevents unauthorized people from eavesdropping on the traffic and allows the user to conduct work remotely.

IPSec is a group of protocols that are used together to set up encrypted connections between devices. It helps keep data sent over a private network secure from intruders. It works by encrypting IP packets along with authenticating the source where they came from.

OpenVPN is a VPN system that implements techniques to create secure point-to-point or site-to-site in routed configurations and remote access facilities. OpenVPN allows peers to authenticate each other using pre-shared secret keys, passwords, or usernames.

Characteristics of Wireguard

  • It is simple and easy to use. Wireguard aims to be as easy as to configure and deploy as SSH. It is capable of roaming between IP addresses. It provides an extremely basic yet powerful interface.
  • Wireguard has minimal attack service. It has been designed with ease of implementation and simplicity in mind. It is meant to be easily in very few lines of code as compared to others such as OpenVPN which is implemented with very large code bases hence can be audited easily by security experts.
  • Wireguard has high performance. Wireguard lives under Linux Kernel which means secure networking can be very high speed. It is both suitable for both small embedded devices such as smart phones and fully loaded backbone routers.
