The modern VPN protocol that's faster, simpler, and more secure than legacy alternatives. Here's why AkcaVPN chose it.
WireGuard is a next-generation VPN protocol created by Jason A. Donenfeld. It lives inside the Linux kernel and is designed to be simple, fast, and use state-of-the-art cryptography. Unlike bloated legacy protocols, WireGuard's entire codebase fits in about 4,000 lines of code.
This minimal attack surface means the entire protocol can be audited by a single person. Compare that to OpenVPN's ~100,000 lines or IPSec's ~400,000 lines, and you begin to understand why WireGuard represents a generational leap in VPN technology.
| Metric | WireGuard | OpenVPN | IKEv2/IPSec |
|---|---|---|---|
| Lines of Code | ~4,000 | ~100,000 | ~400,000 |
| Handshake Time | 1 RTT | 6-8 RTT | 4 RTT |
| Encryption | ChaCha20, Curve25519 | AES-256, RSA | AES-256, DH |
| Throughput | 1011 Mbps | 258 Mbps | 283 Mbps |
| Ping Overhead | +0.4ms | +3.1ms | +1.2ms |
| In Linux Kernel | Yes (since 5.6) | No (userspace) | Partial |
| Auditable | 1 person can audit | Team required | Team required |
The entire WireGuard protocol is ~4,000 lines. This tiny surface area means fewer bugs, fewer vulnerabilities, and easier security audits.
WireGuard establishes connections in a single round-trip. No multi-step handshakes. Connect instantly, roam seamlessly between networks.
Kernel-space execution and modern ChaCha20 encryption achieve near-wire-speed performance. 3-4x faster than OpenVPN in benchmarks.
Uses only proven, modern primitives: Curve25519 for key exchange, ChaCha20-Poly1305 for encryption, BLAKE2s for hashing, SipHash24 for hashtable keys.
While WireGuard is fast and secure, its packet signatures can be detected and blocked by Deep Packet Inspection (DPI) systems used by restrictive governments (China, Russia, Iran, etc).
AmneziaWG is a modified WireGuard implementation that adds packet obfuscation, making VPN traffic indistinguishable from regular HTTPS traffic. It randomizes packet sizes and timing to defeat DPI fingerprinting.
AkcaVPN supports both standard WireGuard (for maximum speed) and AmneziaWG (for censorship-heavy environments). You can switch between them in the app settings depending on your network conditions.
