Can I Use WireGuard® with CyberGhost VPN?
What Is WireGuard?
WireGuard is a high-performance, open-source VPN protocol created by security researcher Jason A. Donenfeld. It was first developed for Linux in 2015 and later expanded to other major platforms, including Android, iOS, Windows, and macOS.
How Is WireGuard® Different from Other VPN Protocols?
WireGuard® is newer and simpler than older protocols like OpenVPN and IPsec. This makes it faster to connect, lighter on your device's battery and CPU, and easier to security audit.
WireGuard® is known for its speed and security. Several key differences set it apart from OpenVPN, IPsec, and legacy protocols:
A few key differences:
- Smaller code base: It uses around 4,000 lines of code compared to over 100,000 in OpenVPN or IPsec. Less code means fewer potential vulnerabilities and better performance.
- Faster authentication: Instead of certificates that need to be renegotiated, WireGuard uses simple cryptographic keys to authenticate devices instantly.
- UDP only: It sends all traffic over UDP, which is faster than TCP-based protocols and reduces battery drain and delays when switching networks.
- Modern encryption: It uses a fixed set of up-to-date encryption methods rather than the older, more complex cipher suites used by OpenVPN and IPsec. This makes it both more secure and more efficient.
