Can VPN traffic be decrypted?

VPN services are used by over 100 million people worldwide. According to Google trends, the frequency of queries about VPN is 82 out of 100. This is a high indicator. People are worried about their safety. With the help of VPN services, you protect your Internet connection and hide it from third parties. This is good because it will make it harder for hackers to break into your traffic. And when connected to public Wi-fi, you won't have to worry about being hacked.

VPNs are protected with encryption keys. In this article we will tell you what it is and how it works. Reading time - 5 minutes.

Can VPN traffic be decrypted?

How encryption works The encryption works

Process like this: you connect to a VPN server. Go to the Internet and enter a request in the search bar. But the request is not immediately sent to the search engine, but to a special secure server. There, traffic is encrypted and already redirected to the search engine. The information received is encrypted again and then shown to you. All this happens in seconds. Therefore, there will be no delays when using top-end VPNs.

Usually services use AES encryption. It is used in the banking system and in the US military armies. This is a clear example of its reliability.

Here is a detailed video on how encryption works:

How a VPN is hacked

To hack a VPN, attackers need to find an encryption key and a sequence of numbers and letters. With AES-256, this is almost impossible to do because this encryption has 1.1 x 1077 combinations. It will take several years to determine a possible combination.

But VPNs get hacked anyway. They do this through protocol vulnerabilities. PPTP is often hacked because it is already 20 years old and does not provide any protection. But the OpenVPN protocol is difficult to crack: it is constantly being improved and modified. OpenVPN has two flavors: UDP and TCP.

UDP improves traffic protection, but some sites will be unavailable. And the internet speed will decrease. TCP keeps the internet speed high, but reduces the security level.

How to protect yourself from traffic hacking

To protect yourself from hacking, we recommend using trusted VPNs. They are ExpressVPN and Nord VPN. We haven't seen a single negative review where people talked about hacks. Here are some more methods of protection against hacking:

  • Do not use free services. They often sell user traffic or encrypt it poorly. If you don't need a VPN subscription, take advantage of the money-back guarantee. It is available in almost all services and is valid for 30 days from the date of purchase.
  • Do not use public networks. Through public Wi-fi, hackers gain access to your device.

What services are better to use

We have tested over 30 VPN services. We recommend 2 of them: ExpressVPN and NordVPN.

Our Top Product Picks

  • Network Lock. If the VPN connection drops, inbound and outbound traffic is blocked. Therefore, confidential information will not be made publicly available.
  • Split-tunneling. Traffic is routed through encryption channels and through regular servers. This is convenient if you need to access certain sites from a real IP.
  • Does not store logs. It is important. Because hackers can steal your data from the company's archives if it keeps logs. ExpressVPN does not record any information, so your data will not be found anywhere.

Released in 2008 in Panama. It has been downloaded by 5 million people. According to Forbes magazine, NordVPN is recognized as the # 1 traffic protection service.

The service uses NordLynx, PPTP, L2TP / IPsec protocols. L2TP and IPsec also work on smartphones. And NordLynx is on computers. NordLynx is a protocol built on top of WireGuard. It's a good protocol, but it's built for speed, not security. Therefore, it loses to OpenVPN in terms of security.
