Initially, VPN were only used as a way of connecting business networks securely over the web. But things have changed these days.

VPN have become very popular, and their uses have continued to diversify as more and more people look to access the web securely and privately.

What is VPN (Virtual Private Network) ?

Theinfowave- A VPN allows you to connect your smartphones, tablets, or computer to another computer known as a server somewhere on the web and browse the web using the internet connection of that computer.
Therefore, if the server is located in a different country, it will look like you are from that country, and you will be able to access the things that you wouldn’t normally.
You can use a virtual private network to:

  • Bypass restrictions on websites or video and audio streaming
  • Streaming media like Hulu and Netflix
  • Protecting your browsing activity on unsafe networks such as Wi-Fi
  • Browse the web anonymously by hiding your true geo location
  • Protect yourself while using torrents
How to Setup a VPN ?

Theinfowave- How you set up your VPN depends on device you would like to use and your VPN service.
Fortunately, most VPN services have easy set-up guides for the most common OS and major devices.

Here are simple steps on how to set up a VPN:
  1. Choose a reliable VPN service
  2. Purchase a subscription that suits you
  3. Download and install the software on your device
  4. Login into the VPN service
  5. Connect to the VPN server and start browsing the web securely and privately
Devices that use Windows, Mac, Android or iOS have a built-in VPN that uses IPSec/IKEv2 or IPSec/L2TP protocols in place of OpenVPN.
If you choose route, you will have to download VPN configuration files from your VPN service.
However, most people use Virtual Private Network through a VPN app or VPN client. This allows them to not only establish private networks but also access all the leak protection settings and features.

How Does A VPN Wok?

Theinfowave- One of the most common questions people ask ‘how do vpn works’.
A VPN works by establishing a safe, secure, and private network between the VPN client, which is your device, and the VPN’s private server.
This way, the encrypted data transmitted from your device to the internet appears as though it is coming from the VPN server and not your computer.

You can think of a VPN as a secure “tunnel” through which data is transmitted between the VPN client and VN server via the web.
Your online destination sees the data from your computer as coming from the location of the VPN service and not your real geographical location.

A VPN encrypts your data because you are using their software and goes straight your internet service provider in encrypted form then to the VPN server. Basically, the VPN server acts like a third party that connects to the internet on your behalf.

Any device that connects to the internet, whether it is a computer, iPad, tablet, or smartphone, has a unique IP (Internet Protocol) address. Your IP address and geographical location could easily be traced if you don’t use a VPN when connecting to the internet.
A VPN will replace your IP address with that of the VPN server to hide your real geographical location.

VPNs service providers have servers around the world, which gives you a wide range of options.


VPN Encryption And protocols

Encryption


AES, which stands for Advanced Encryption Standards, is a pretty common abbreviation in the tech industry.
Nearly all VPNs today use AES key, which can either be 128-bit or 256-bit. The 128-bit encryption remains the most secure in establishing private networks despite the recent advancements in quantum computing.

Protocol

There are a few VPN protocols you can use with your VPN application to create private networks.
But before we discuss them, let’s define a VPN protocol.
A VPN protocol is a set of instructions or rules used by VPN providers to establish a safe and secure connection between VPN client and VPN server.
Here are the most common VPN protocols:


OpenVPN

This is by far the most secure protocol. The open-source commercial software is compatible with many devices, which makes it a versatile protocol. In addition, it has a number of features and can be used over UDP or TCP ports.
OpenVPN utilizes a custom security protocol that uses OpenSSL and TLS for key exchange.


IKEv2/IPSec

IKEv2/IPSec (Internet Key Exchange version 2/ Internet Protocol Security) is a fast and high-performance VPN protocol. This protocol is pre-built into most Operating Systems and plays a key role in restoring lost connection.
On the downside, IKEv2/IPSec is not open-source as it is a creation of Microsoft and Cisco.
But it remains the best option for mobile devices mainly because it is lightweight, fast, secure, and quickly re-establishes lost connections.


PPTP

PPTP (Point-to-Point Protocol) is an obsolete VPN protocol built into most Operating Systems. The downside of this protocol is that it has many security vulnerabilities.


L2TP/IPSec

L2TP/IPSec (Layer 2 Tunneling Protocol/ Internet Protocol Security) is another popular VPN protocol.
It is more secure than PPTP, but it is not fast as it double-encapsulates data packets. L2TP/IPSec is pre-configured into most Operating Systems and commonly used on mobile devices.


WireGuard

This is the latest protocol that promises better security and enhanced performance.
WireGuard is a free open-source software app protocol that implements VPN techniques to establish a safe and secure point-to-point connection in bridged or routed configurations.
Each protocol has its pros and cons, but the most reliable and widely used is OpenVPN. This is because it is an open-source software application that delivers excellent performance.
Most VPN providers will allow you to choose the protocol you want to use. But when using VPN on your mobile device, you will only have access to a limited number of protocols.
