What cryptography does WireGuard utilize?

WireGuard is built upon modern high-speed cryptographic primitives: Curve25519 (for ECDH key exchange), ChaCha20-Poly1305 (for authenticated encryption), BLAKE2s (for hashing and PRF), and SipHash24 (for hashtable keys).

Are my private keys sent to any server?

Never. All WireGuard key pairs, pre-shared keys, and client configs are generated 100% locally in your browser using the Web Cryptography API. Your keys never touch a remote network.

What is a WireGuard Pre-Shared Key (PSK)?

A Pre-Shared Key (PSK) adds an extra layer of symmetric encryption on top of the Curve25519 key exchange to provide post-quantum resistance against future quantum computer harvest-now-decrypt-later attacks.

Why WireGuard Outperforms OpenVPN & IPsec

Created by Jason A. Donenfeld, WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. With fewer than 4,000 lines of code (compared to over 100,000 lines for OpenVPN), it resides in the Linux kernel space, offering immense throughput, instant roaming connections, and sub-second handshake speeds.

WireGuard abandons complex certificate authority handshakes in favor of cryptokey routing: pairing fixed Curve25519 public keys with permitted IP addresses.

Frequently Asked Questions

What does AllowedIPs = 0.0.0.0/0 do?

Setting AllowedIPs = 0.0.0.0/0, ::/0 enables a full tunnel, routing 100% of your device's internet traffic through the WireGuard VPN gateway.
