WireGuard
WireGuard is a modern, open-source VPN (Virtual Private Network) protocol and software that provides secure, fast, and simple network tunneling. It uses state-of-the-art cryptography, such as the Noise protocol framework, Curve25519, ChaCha20, and BLAKE2s, to ensure robust security with minimal configuration. Designed to be lightweight and performant, it is often integrated into the Linux kernel and available as cross-platform applications for various operating systems.
Developers should learn and use WireGuard when they need to establish secure, encrypted connections between devices, such as for remote access to servers, connecting cloud resources, or creating private networks for distributed applications. It is particularly valuable for scenarios requiring high performance and low latency, like gaming or streaming, due to its efficient design, and for DevOps tasks where simplicity and security are prioritized over complex VPN setups.
