What is the WireGuard VPN protocol?

If you've ever heard the term VPN and felt confused by strange protocol names like OpenVPN or iKEV2, today we have a new friend to introduce to you. It's called WireGuard. It sounds like the name of a rock band, but in reality, it's the hottest VPN technology of the moment.

WireGuard stands out for its speed and security. It's easy to use, so you don't have to deal with complicated settings. Importantly, it is designed to be modern, fitting into an era where everything needs to be fast and secure at the same time.

This article will introduce you to WireGuard, explaining what it is, how it works, and why many people are starting to use it instead of the old protocols they used to know.

What is WireGuard?

WireGuard is a new VPN protocol designed to connect to the internet securely, quickly, and more simply than previous protocols. It acts as an "encrypted tunnel" that allows our data to reach its destination without being intercepted or compromised along the way.

The highlight of WireGuard is its speed because it is written with only a few thousand lines of code (compared to OpenVPN, which has hundreds of thousands). This makes it work quickly, easy to set up, and less prone to vulnerabilities. Additionally, it supports multiple systems such as Windows, macOS, and mobile devices on both iOS and Android.

In summary, if you want a VPN that is both secure, easy to use, and doesn't consume too many system resources, the WireGuard protocol is definitely a choice to watch in this era.

The format of WireGuard

The use of the WireGuard protocol can be divided into two main types based on the connection characteristics as follows….The use of the WireGuard protocol can be divided into two main types based on the connection characteristics as follows….

1. Peer-to-Peer (P2P)

For WireGuard, every connected device is called a "peer," not a client or server like in traditional VPNs. Therefore, you can configure two devices to connect directly in a point-to-point manner without a central server. This is suitable for personal use, such as connecting a home computer to a laptop taken to work.

2. Client-Server

Although WireGuard does not adhere strictly to the client/server model, in practice, we can configure one machine as a "server" that supports connections from multiple "clients," similar to traditional VPNs. This setup is suitable for use in organizations or VPN service providers with a large number of users.
