What is WireGuard?
WireGuard is an open-source virtual private network (VPN) tunnel that provides secure and private network connections. It is designed to be a straightforward and efficient alternative to other VPN solutions, focusing on modern cryptography and a lean protocol. Developers and network administrators use WireGuard to establish secure communication channels for various applications. Developers and administrators configure WireGuard by exchanging public keys, similar to how SSH keys are used, to establish a VPN connection. The system handles the underlying network complexities transparently. It uses cryptography to secure data transmission and supports roaming between IP addresses. This allows for secure networking across different environments.
