OpenVPN vs WireGuard: The Best VPN Protocol

OpenVPN has almost go synonymous with VPN clients and rightly so. Information technology's one of the fastest, most secure, and reliable VPN protocols out at that place. No matter which operating system y'all are on, most of the VPN clients have OpenVPN as their default tunneling protocol. Having said, there is talk of an OpenVPN alternative that claims to bring better performance and is much easier to gear up up. Yes, I am talking about WireGuard. While WireGuard is relatively new, information technology holds a lot of promise and that's why we bring y'all an in-depth explainer on OpenVPN vs WireGuard. In this article, we talk about their similarity and differences and take you through some important aspects of WireGuard. So without further delay, let's begin.

OpenVPN vs WireGuard: A Brief Introduction

Before I brainstorm, I want to give a brief overview of the development history and business organization model of both the VPN protocols. As most of us know, OpenVPN is amidst the oldest VPN protocols which was first released in 2001. It's an open-source VPN protocol and run past the OpenVPN projection. Having said that, OpenVPN is non costless to utilise either for personal or commercial users then continue that in heed. Still, you tin employ the OpenVPN Community Edition for free, but with very limited features.

Coming to WireGuard, information technology's relatively new and was first released in 2016. Similar to OpenVPN, WireGuard is open-source, just likewise gratuitous for both commercial and personal users. So far, we have not seen a stable release as the work is nevertheless in progress and not ready for product. However, Mullvad and IVPN have implemented the WireGuard protocol in their VPN customer for initial testing. As an bated, in Jan 2020, WireGuard was finally merged into the Linux Mainline kernel and it'south expected to ship with the side by side kernel release. What information technology means is that you will be able to utilize WireGuard on any Unix-based operating systems (Android, iOS, macOS, Linux) natively. As for the business model, WireGuard has received donations from many big VPN companies similar PIA and IVPN.

At present that we have learned about the basics, let's move to the security aspect of OpenVPN and WireGuard.

one. Security

When we talk about VPN protocols, security is treated as the superlative priority, hence, let's begin with OpenVPN's security start. Since OpenVPN has been hither for so long, it has gone through many security audits and has been found secure and reliable without whatsoever glaring vulnerability. It has a CVE tracking mechanism where publicly known security vulnerabilities and exposures are reported and patched regularly. On the technical forepart, OpenVPN uses a custom security protocol based on SSL and TLS protocols. If y'all are unaware, TLS (Transport Layer Security) is one of the best cryptographic protocols which provides secure advice between two endpoints. In fact, this protocol is used by iPhones to share files through AirDrop.

Apart from that, OpenVPN utilizes OpenSSL which is a library of security protocols to identify other parties in the network and prevent eavesdropping. Another of import security attribute of OpenVPN is that information technology operates in user space — a segregated space where virtual memory is protected against rogue programs and attackers. All in all, OpenVPN is a pretty secure protocol and the company continuously develops new technologies to combat malicious attacks.

Talking about WireGuard, it uses SSH (Secure Trounce) protocol to communicate between devices. It's a cryptographic network protocol just similar TLS that offers a great range of security features. But that is not all. Unlike OpenVPN which runs in a user space, WireGuard runs inside a Linux module chosen the kernel infinite . What it means is that all the operations happen within the deep layer of kernel, away from the operating system. As a result, the operations remain quick and secure — even ameliorate than OpenVPN.

two. Encryption

While encryption is part of security, we have mentioned it separately to emphasize on various algorithmic techniques used by OpenVPN and WireGuard. As I said to a higher place, OpenVPN utilizes a security suite called OpenSSL which provides a range of 256-bit cryptographic algorithms like AES, 3DES, BlowFish and more than. The algorithms are so powerful that it tin can traverse through NAT servers and firewalls without breaking the connectedness.

Every bit for WireGuard, it uses a number of cryptographic algorithms to protect information transmission from brute-strength attacks. Some of the algorithms are 128-scrap Curve25519, Poly1305, Diffie–Hellman Elliptic-curve and more than. On summit of that, WireGuard brings HKDF to derive keys from third-party endpoints. Not to mention, there are defended protocols for hashing and key derivation too. Simply put, both OpenVPN and WireGuard are excellent when information technology comes to using encryption methods and maintaining secrecy.

3. Authentication

At present we come up to another of import attribute of VPN protocols: Hallmark. OpenVPN uses 2 ways to authenticate betwixt parties in a network. One is Certificate-based authentication which is the most secure method, only information technology'due south slower in execution and some other is Pre-shared keys which is the fastest mode, but relatively less secure. Depending on the network environs, OpenVPN uses either of the authentication methods, but y'all tin can choose your own configuration too for better security.

If nosotros talk about WireGuard, it deploys RFC 7539's AEAD method to authenticate endpoints in a network. And the authentication is also encrypted using the Poly1305 cryptographic cipher. For general users, information technology might not brand much sense, but in unproblematic terms, it means that a handshake request is sent to all the devices in a network. Later on that, it waits for the responder to decrypt the bulletin and hence, a connection is established.

four. Performance

In this battle of OpenVPN vs WireGuard, the major departure between the two protocols is performance. The reason WireGuard is touted to be the VPN protocol of the time to come is that it offers about 2X performance jump than what OpenVPN offers. And the reason is quite simple: dissimilar OpenVPN which runs as an application, WireGuard runs equally a module inside the Linux kernel. So the cryptographic services are executed really fast while operating encryption or decryption processes. Apart from that, due to the deep integration with the kernel, there is not much layer to interact with which saves time significantly.

But that is not all. OpenVPN has 400,000 lines of code which is simply huge whereas WireGuard has simply 4,000 lines in its codebase. If you know a flake of programming, yous would know that a smaller codebase translates to faster performance. So, if you desire to implement WireGuard in your private VPN, you are going to be surprised on the functioning front end.

v. Platform Support

OpenVPN is available everywhere including Windows, macOS, Linux, iOS, Android, Windows Phone and more. In fact, almost all the modern VPNs are based on OpenVPN protocol. We have covered the best VPN for Windows, Android, iPhone, iPad and macOS so check those lists too. Other than that, OpenVPN's protocol is also used in many routers' firmware for tunneling data packets in a secure method.

Coming to WireGuard, the VPN protocol is implemented in a few VPN clients and you tin get them on Windows, Android, macOS, iOS and Linux. Some of those VPN clients are Mullvad, IVPN, and Tunsafe. Notwithstanding, in the coming months, when WireGuard volition be released with Linux kernel, it will exist natively available every bit a kernel module on all UNIX-like operating systems. And that includes Android, macOS, iOS, iPadOS, and Linux.

So at this point, WireGuard is nowhere near OpenVPN in terms of adoption and platform support. Nonetheless, later the upcoming Linux kernel release and subsequent adoption by Google and Apple, many mainstream VPN clients like ExpressVPN and PIA may start implementing the WireGuard protocol in their apps.

OpenVPN vs WireGuard: What's the Verdict?

So that was our deep dive into OpenVPN and WireGuard and in what ways they are similar or unlike in their approach. For a long time, OpenVPN has been the de-facto protocol non merely for VPN clients merely likewise for any kind of network tunneling exist it in routers or network servers. Withal, WireGuard has come with lots of promise in the performance and setup front. And so now we will have to look and see if VPN companies are adopting the WireGuard protocol or not. Anyway, that is all from us. If you constitute the commodity informative, do comment down below and let us know.
