Wireguard vs OpenVPN – Advantages and Disadvantagesīecause Wireguard uses public-key encryption, Wireguard requires static IP addresses. We’ll discuss that in more detail as we explain the advantages and disadvantages of Wireguard and OpenVPN. In comparison, Wireguard uses public-key encryption for authentication. It can use username and password or certificates for authentication. OpenVPN is based on SSL/TLS, and it uses the OpenSSL library for cryptography. By defining the cipher suites, Wireguard ensures that devices and servers follow the best security protocols.Īnother difference between Wireguard and OpenVPN is the way they authenticate the server. But it also opens the door to poor implementations that can expose vulnerabilities. OpenVPN supports various cipher suites that allow older devices to support the protocol. Because it has fewer lines of code, there are fewer chances of potential vulnerabilities. And it proves that point by the fact that Wireguard has only 4000 to 5000 lines of code versus 400,000 lines of code for IPsec. Wireguard wants to be that new protocol that is leaner and faster. Blocking the port would mean that web traffic cannot pass through the firewall.īut OpenVPN launched 20 years ago. Running OpenVPN in TCP is particularly helpful for bypassing firewalls as it uses port 443, which is also the port used by HTTPS traffic. The VPN protocol has evolved over the years and has been widely praised for its cryptography support and the fact that it can run in both UDP and TCP mode. OpenVPN has become a favorite in the VPN industry since its introduction in 2001. Here are the algorithms used by Wireguard: Wireguard does away with this choice by defining the algorithms. ![]() The VPN server will communicate on the highest cipher suite the client supports. As a VPN protocol, OpenVPN supports various cipher suites, including multiple key exchange, symmetric key encryption, message authentication, and hashing algorithms. One of the ways Wireguard addresses vulnerabilities is by eliminating the choice of cipher suites. It also allows the community to find security vulnerabilities so that they can be addressed quickly. Just like OpenVPN, Wireguard’s source code is not proprietary, which means anyone can take the code and modify it, and set up an implementation based on the protocol. The VPN protocol promises to be fast, secure, and more modern than its counterparts.Īn immediate plus for Wireguard is its open-source nature. Wireguard is a new VPN protocol introduced to the world in early 2021 after a beta phase. Wireguard is a new VPN protocol that is catching a lot of interest due to the reasons that we’ll explore in this blog and compare Wireguard vs OpenVPN to help you understand which is more capable. There are several VPN protocols in use today, each offering something better or worse. A protocol provides a standard through which two devices can communicate without throwing up errors. VPN protocols are a fundamental component that decides how reliable and secure your connection will be. JanuBy Nick Anderson No Comments 4 minutes Wireguard vs OpenVPN – What Are the Differences?
