Which encryption does WireGuard support
WireGuard uses a fixed set of modern, high-performance cryptographic protocols. It includes ChaCha20 for symmetric encryption, Poly1305 for authentication, Curve25519 for key exchange, BLAKE2s for hashing, and HKDF for key derivation. This combination ensures both speed and security without relying on outdated or vulnerable algorithms.
How WireGuard differs from other protocols
WireGuard is faster, simpler, and more secure than traditional VPN protocols like OpenVPN or IPSec. It has a smaller codebase, making it easier to audit and less prone to bugs. Its advanced cryptographic design, quick connection times, and mobile-optimized performance give users a smoother, more reliable VPN experience.
WireGuard authentication explained
WireGuard uses public key cryptography instead of usernames and passwords. Each device has a private and public key pair. The public key is shared with peers, while the private key stays hidden. When a connection is made, keys are exchanged and verified to authenticate devices securely.
How WireGuard authentication works
Authentication happens through a secure handshake using cryptographic key pairs. The client sends encrypted data signed with its private key, which the server verifies using the client’s public key. Once both sides verify each other, an encrypted VPN session is established automatically and securely.
