Talk#2: Why does ExpressVPN switch from C to Rust for Lightway’s code? by Thomas Leong
We built Lightway from scratch in a quest to offer a VPN protocol that serves the needs of VPN users in a modern, mobile world—one that’s fast, secure, and reliable. Since launching Lightway five years ago, we’ve had it open-sourced and audited, as well as implementing key upgrades. We have just rolled out a new version of Lightway to users—one that sees our pioneering VPN protocol rewritten in Rust programming language. For this technical talk, we wanted to take a moment to discuss some of the more technical reasons behind the changes we’ve made and dive into the benefits of Rust over C, the language we originally used for Lightway code.
