WireGuard, a brainchild of Jason Donenfeld, is a revolutionary approach to Virtual Private Networks (VPN) that runs on Linux and now is in Linus Torvald’s code tree. It is designed as an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache.
It is expected that as early as April 2020, WireGuard should appear in the Linux kernel 5.6 release. What’s the big deal?
Unlike WireGuard virtually all VPN services run off Linux servers. As they explain on their website, the the fact that WireGuard lives inside the Linux kernel along with extremely high-speed cryptographic primitives means that secure networking can be very high-speed. It is suitable for both small embedded devices like smartphones and fully loaded backbone routers.
WireGuard is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry.
WireGuard also accepts cryptocurrencies. Paying for your VPN is also done by Bitcoin or your favorite cryptocurrency, such as Ethereum and Litecoin, providing even more anonymity. You can launch a VPS with WireGuard VPN using Bitcoin and be up and running within minutes.
WireGuard’s code, which is licensed under the open-source Gnu General Public License (GPL) version 2.0, is already available on Android, Windows, macOS, BSD Unix, and iOS. This make transition easier for those who sense where the wind is blowing. Some VPN services, such as StrongVPN and Mullvad VPN are moving their software stacks to WireGuard. In part, they are doing this also because as WireGuard claims, “Compared to behemoths like Swan/IPsec or OpenVPN/OpenSSL, in which auditing the gigantic codebases is an overwhelming task even for large teams of security experts, WireGuard is meant to be comprehensively reviewable by single individuals.”
This simplicity doesn’t come at the sake of security, as WireGuard incorporates state-of-the-art cryptography technologies such as the Noise protocol framework, Curve25519, ChaCha20, Poly1305, BLAKE2, SipHash24, and HKD.
WireGuard is a new page in the book of VPNs. But it’s launch will not immediately put an end to other VPN technologies. Yet, experts from ZDnet believe if WireGuard lives up to its promise, we’ll see the demise of VPN technology as we know it.
