VPN protocols

Ready to use a VPN service? Then you need to learn some info about VPN protocols to make sure your VPN provider gives you the top online protection and security.

Let’s start with the definition. A VPN protocol refers to a set of processes that VPN providers use to ensure you get a secure and fast connection to VPN servers and back. Simply stated, it is a method by which your device connects to a VPN server.

VPN protocols and which is the best to use - What is the safest VPN protocol?

KeepSolid VPN Unlimited offers a variety of protocols, each with unique capabilities and strengths. Consider what protocols your device supports, and whether any of them are blocked by your network. Then, choose the one with a balance between security, online freedom, and speed that is best suited to your needs.

By default, KeepSolid VPN Unlimited uses the optimal protocol for your network, but you can also configure your app to use other protocols. Just choose the one you would like to try in your VPN settings. Here is a chart with all possible options that are currently available:

Platform Available Protocols
Android IKEv2, OpenVPN, KeepSolid Wise TCP/UDP
Windows Standalone version IKEv2, OpenVPN, KeepSolid Wise TCP/UDP
Windows Store version IKEv2
Windows Mobile L2TP
iOS IPSec (for older OS versions), IKEv2, OpenVPN, KeepSolid Wise TCP/UDP
macOS IPSec (for older OS versions), IKEv2, OpenVPN, KeepSolid Wise TCP/UDP
Linux IKEv2 OpenVPN, KeepSolid Wise TCP/UDP
Google Chrome, Mozilla Firefox, Opera TLS encryption

You don’t need to settle for just using a single VPN protocol. For instance, if you’re an online gamer or just watching favorite live sports then connection speed is more important for you now. IKEv2 will be really useful for this case. And if your target is to keep your sensitive personal data extremely secure, go for OpenVPN.

Encryption

According to Edward Snowden, “properly implemented strong crypto systems are one of the few things that you can rely on.” This means that the encryption does work.

The encryption itself is a process of encoding messages or information that makes sense in such a way that only authorized parties can read it. For interceptors, the encoded message looks like gibberish. The commonly used encryption methods are 128-bit and 256-bit (in a key length). They are considered to be of military level, and are widely used by the US government to protect their “sensitive” data.

Generally, 128-bit encryption is uncrackable through brute force, and it is believed to be so for another hundred years or so. However, taking into account the scale of resources that the NSA seems to have thrown at cracking encryption, it is a good practice to upgrade cipher key lengths to 256-bit. This key would require twice as much computational power to break it as a 128-bit one.

That’s why KeepSolid VPN Unlimited uses the 256-bit encryption algorithm, to ensure the best security and performance.

Ciphers

A cipher is a mechanical operation, known as an algorithm, and used for performing the encryption or decryption of a certain information, such as video files, images, or simple messages. The encrypting/decrypting procedure depends on the key, a piece of auxiliary information which changes the detailed operation of the algorithm.

KeepSolid VPN Unlimited uses AES cipher that, today, is generally considered to be the most secure cipher for the VPN use, as well as for all other applications that now exist. It is highly efficient on a wide variety of hardware, from smartphones and tablets, to high-performance computers.

With the AES cipher together with the 256-bit key, KeepSolid VPN Unlimited makes our users strongly protected and secured while they are surfing the web.
