How does WireGuard work?

WireGuard is a modern VPN protocol designed for simplicity and security. Unlike traditional VPNs, WireGuard operates on a peer-to-peer basis, with each peer possessing a set of private and public keys. These peers exchange public keys, similar to swapping phone numbers, to establish a secure connection.

WireGuard employs modern cryptographic methods, including Curve25519 for key exchange, ChaCha20 for encryption, Poly1305 for authentication, and BLAKE2s for hashing. These choices ensure that WireGuard remains resistant to various known cryptographic vulnerabilities.

One of WireGuard's standout features is its statelessness between authenticated peers. It does not send unnecessary "alive" messages, hence conserving bandwidth. Furthermore, it supports roaming, allowing devices to switch connections, like moving from WiFi to cellular data, without dropping the VPN connection. The protocol also offers built-in NAT traversal, making connections easier to establish in modern network environments.

Performance-wise, WireGuard is designed for speed, achieving high throughput and low latency. It can also efficiently distribute workloads across multicore processors. With a rapid connection establishment and compatibility across platforms like Linux, Windows, macOS, and mobile devices, WireGuard provides a streamlined and secure VPN experience for users.

Is WireGuard free?

Yes, WireGuard is free. It is open source software, which means that its source code is publicly available and can be used, modified and distributed by anyone. WireGuard is released under the GPLv2 license, which promotes transparency and community contribution. This openness ensures that protocols can be audited for security vulnerabilities and any improvements or modifications can be shared freely with the wider community. However, while WireGuard itself is free, there may be costs associated with using WireGuard to access VPN services, such as the cost of purchasing a WireGuard VPS server, which you can do directly with LightNode VPS for as little as $7.71/mo, and hourly billing!

How safe is WireGuard?

WireGuard is considered highly safe. It employs modern cryptography, has a simple and easily-auditable codebase, and is open-source, allowing for continuous security evaluations. However, like any software, it's vital to keep it updated and use best practices for optimal security.
