WireGuard: The Most Elegant VPN Ever Built

Hey, paranoid friend! 👋

WireGuard isn’t just another VPN protocol. It’s a reimagining of what network code should look like: ~4,000 lines versus 400,000 in OpenVPN. Less code = fewer vulnerabilities = smaller attack surface.

But most WireGuard articles are just “copy this config and run” tutorials. Today we’re going deep: how it works under the hood, which parameters actually matter for privacy and speed, and why Linus Torvalds called it a work of art.
