WireGuard VPN Is On Its Way To Linux

WireGuard has now been committed to the mainline Linux kernel. "While there are still tests to be made and hoops to be jumped through, it should be released in the next major Linux kernel release, 5.6, in the first or second quarter of 2020," reports ZDNet. From the report: WireGuard has been in development for some time. It is a layer 3 secure VPN. Unlike its older rivals, which it's meant to replace, its code is much cleaner and simple. The result is a fast, easy-to-deploy VPN. While it started as a Linux project, WireGuard code is now cross-platform, and its code is now available on Windows, macOS, BSD, iOS, and Android. It took longer to arrive than many wished because WireGuard's principal designer, Jason Donenfeld, disliked Linux's built-in cryptographic subsystem on the grounds its application programming interface (API) was too complex and difficult. He suggested it be supplemented with a new cryptographic subsystem: His own Zinc library. Many developers didn't like this. They saw this as wasting time reinventing the cryptographic well. But Donenfeld had an important ally. Torvalds wrote, "I'm 1000% with Jason on this. The crypto/ model is hard to use, inefficient, and completely pointless when you know what your cipher or hash algorithm is, and your CPU just does it well directly." In the end, Donenfeld compromised. "WireGuard will get ported to the existing crypto API. So it's probably better that we just fully embrace it, and afterward work evolutionarily to get Zinc into Linux piecemeal." That's exactly what happened. Some Zine elements have been imported into the legacy crypto code in the forthcoming Linux 5.5 kernel. This laid the foundation for WireGuard to finally ship in Linux early next year.
