VPN Encryption for Supreme Privacy: Essential Details Here
VPN Encryption. If you haven’t heard of this word, you’re missing out big time, as this is one of the most notable technologies deployed to safeguard the digital presence of the end users. Seeing its massive contribution to online security, many consider VPN a godsend.
It has become so mainstream that, as per Security.org, nearly 68% of US adults are using VPN. Before you think of using one, understanding ‘how does VPN work’ is crucial. In this post, we will spill every bean on VPN encryption and explain its essential aspects. So, let’s get started.

How Does VPN Encryption Work?
A VPN without robust VPN encryption is useless as its absence will expose all the online activities of the end-users. It’s the VPN encryption that protects the digital privacy of the end-users.
These stages begin with getting connected with the VPN, following the workflow as under:
|
Step 1 |
Plain and readable text |
As soon as the user and server are connected, encapsulation of data as encrypted packets begins. |
|
Step 2 |
Well-encrypted or ciphertext |
These encrypted data packets pass through the highly encrypted tunnel. The tunnel features multiple VPN encryption protocols and transports the data traffic to the remote VPN server. |
|
Step 3 |
The decryption of text and converting it into plain and readable form |
The powerful server decrypts it, converts it into simple, readable text, and sends it to the requested website. |
Using this workflow protects the online privacy of the end user and makes the online domain a safer place to be. The anonymity of the end-user is maintained throughout the encryption domain VPN usage duration.
While all this happens, factors like the best VPN encryption algorithms, protocols, ciphers, VPN encryption types, and many others play an essential role. Let’s have a quick yet crisp understanding of them.
What are the Types of Encryption?
The most commonly used VPN encryption is of two kinds, symmetric and asymmetric. Here is a detailed explanation of these two customary encryption types:
- Symmetric Encryption
It is a private key-based encryption algorithm that deploys the same key for plaintext encryption and ciphertext decryption. To make this encryption work, having the same key for the sender and receivers is imperative.
Users of this VPN encryption must exchange the data decryption keys with others. It is the most common type of VPN encryption. But, there is a drawback as well. For instance, if anyone gets to hold the private key used, he can decrypt the entire encrypted data in no time.
- Asymmetric Encryption
In this kind of encryption, two different keys, public and private, are used.
It’s also known as public-key cryptography. The discreet private and public keys are exchanged using the internet or an extensive network in this kind of VPN encryption. The public key is accessible to everyone, while the private key is a secret preserved.
Regarding speed, understand that this encryption is slower than symmetric VPN encryption because the keys are long and complex calculations.
Keeping keys safe is an easy and more doable job in this kind of VPN encryption. So, you will get an extra bout on online safety.

How Many VPN Networks Offer Data Encryption?
When we talk about security and encryption, the kill switch is something we can’t put in the back seat as this plays a crucial role in one’s online safety. This unique feature keeps your data safe in case internet connectivity blurs in the middle.
The sudden absence of an internet connection to the VPN network allows hackers to barge into your online presence and steal crucial information. The kill switch feature gets automatically activated and provides the default IP address to the end user. This way, your online presence remains safe from beginning to end.
In the next minute, we’ll explain some of the best VPNs that offer a great VPN kill switch.
| ExpressVPN needs no introduction as this VPN has won many hearts with its extensive server and high-end security features. The excellent Express VPN encryption facility includes an automatic kill switch that keeps the network traffic far away from accessing your crucial details. | |
| NordVPN is our second-best bet, as its cutting-edge encryption and features grant excellent online traffic security. It features double encryption and Tor for added online protection. Its kill switch keeps the traffic protected and is capable of safeguarding your online identity. | |
| This VPN is one of the most notable commercial VPNs with a kill switch. Along with an automatic kill switch, it protects against IP, DNS, and WebRTC leaks. It’s a safe bet to make as it uses cipher (256-AES-GCM), Open VPN encryption, IKEv2/IPSec, and WireGuard to protect the end-user. | |
| If you’re looking for a fast and reliable kill switch for Windows and Mac, then IPVanish is here to help. People in more than 60 countries can easily use it. Its kill switch is highly powerful and gets active immediately. The use of 256-bit encryption and a no-logging policy ensures that the end user’s privacy is unharmed. |
How to Test VPN Encryption? The List of Recommendations
By now, it must be clear to you that if you want to feel protected in the online world, then the VPN encryption domain should be strong. But, as a layman, you can’t get into the details and find out how to do the VPN encryption test. Well, we’re going to teach you this as well.
Take the help of Wireshark
For beginners, Wireshark is a very famed data-analyzing software featuring more than two thousand protocols. With the help of this tool, it’s easier to figure out the data packets used for traffic and help you decide whether or not the VPN encryption is dependable. The best part of using this tool is that it explains the results in very plain and understandable language.
Here are the steps to follow to use this tool:
- Get the tool on the desired device and run it.
- Turn on the VPN and connect it to the server of your choice.
- Connect it using Ethernet or WiFi and record its performance.
- Go to the Protocol section and select OpenVPN; if you want to check another encryption protocol, then select that one.
- Right-click on the encryption and check the kind of port it’s using.
If there is no mention of scrambled or unreadable data, it means that VPN is not encrypting the data correctly. It’s better to change the VPN service provider.
Bring Glasswire into action
If you want to know ‘how to test my VPN encryption strength’ in the least possible hassles, then the right move to make is using Glasswire. It is another valuable tool for checking the viability of VPN encryption. Follow these steps to make it work for you.

FAQs
Internet Key Exchange version 2 or IKEv2 is a type of tunneling protocol that uses IPsec for encryption and authentication. It is a key exchange protocol using Diffie-Hellman key exchange. It works well in using acknowledgments, error processing, transmission control, and a built-in Network address translation traversal. When clubbed with IPsec, it becomes faster and safer.
