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.

mTLS in Microservices: Mutual Authentication

In traditional HTTPS, only the server proves its identity with a certificate. The client remains anonymous. But in microservices, where services communicate with each other, we need mutual trust. This is where mTLS (mutual TLS) comes in.

TLS 1.3: What Changed and How to Migrate

Hey defender! 👋

TLS 1.3 isn’t just another protocol version. It’s a revolution in internet security: faster, more secure, simpler.

But migrating from TLS 1.2 isn’t just updating a config. You need to understand what changed, what will break, and how to migrate properly.

Let’s explore key TLS 1.3 changes, practical examples, and a step-by-step migration plan 🚀
