Aox VPN official website technology blog: The past and present of VPN encryption

The past and present of VPN encryption

VPN encryption technology has experienced more than 20 years of development. From the original simple PPTP to today's WireGuard, each generation has made a qualitative leap.

First generation: PPTP (1995)

PPTP developed by Microsoft is the earliest VPN protocol. It is fast but has extremely poor security. MPPE encryption has been cracked many times. In 2020, Microsoft officially recommends against using PPTP.

Second generation: IPSec (1998)

IPSec security is much better than PPTP, but the configuration is extremely complex and the implementation is error-prone. There are also problems with NAT traversal, and the connection is often unavailable behind a firewall.

Third generation: OpenVPN (2001)

OpenVPN is based on OpenSSL and solves the configuration problem of IPSec. But 100,000 lines of code brings more potential vulnerabilities, and the performance is not ideal.

Fourth generation: WireGuard (2018)

WireGuard has only 4,000 lines of code, uses the most advanced encryption algorithm, is fast, secure, and simple. AoxVPN chose WireGuard precisely because it completely outperforms the previous generation in all aspects.

VPN technology is constantly improving, and Aox VPN always uses the most advanced solutions. Go to the official website for details.
