It&rsquo;s a <strong>reimagining of what network code should look like</strong>: ~4,000 lines versus 400,000 in OpenVPN. Less code = fewer vulnerabilities = smaller attack surface.</p> <p>But most WireGuard articles are just &ldquo;copy this config and run&rdquo; tutorials. Today we&rsquo;re going deep: <strong>how it works under the hood</strong>, <strong>which parameters actually matter for privacy and speed</strong>, and <strong>why Linus Torvalds called it a work of art</strong>.</p>
