What is a VPN? And How does it work?
What is this VPN?
VPN is full meaning, ‘Virtual private network’ (Virtual private network) When multiple computers (or separate networks) are brought under the same network through a public network, they are called VPN. It serves as a way to secure communication and encrypt data. We usually use VPNs to protect our privacy online.
Types of VPN?
There are several types of VPNs available to Internet users. And each VPNE offers security and opportunities from different angles. VPN gula is divided into different categories according to their protocol and usage. So if you have an idea about all types of VPN, it will be helpful to find the one you need.
PPTP: PPTP is a very common point-to-point tunnelling and has been used since Windows 95. PPTP is very easy to set up but due to its age, it is easy to find vulnerabilities and can be attacked by hackers.
SSTP: The full form of SSTP is a secure socket tunnelling protocol. Which supports Microsoft’s protocol and Windows. It uses SSL v3 and can bypass the firewall. SSTP is considered to be more secure and effective than PPTP.
L2TP / IPsec: Layer 2 Tunnel Protocol does not actually offer any encryption. This is considered effective encryption but all traffic is encrypted from L2TP and then added to the top resulting in slower operation than other options.
Open VPN: Open VPN is used in open search technology such as: SSL, V3 / TLS v1 protocol and OpenSSL encryption library. Open VPN is highly configurable and one of the safest options on the web.
IKEv2: Internet Key Exchange version 2 also called IKEv2. It was created in 1997 through a partnership with Microsoft Cisco. Which uses the X.509 certificate in the pairing protocol for authentication.
Why use VPN?
VPN is used for three main reasons:
1. Privacy (So the main function and purpose of VPN is to protect your privacy online
2. unblocking (The second purpose of using VPN is to unblock! You may know that there is some content that can only be viewed or used in certain countries (such as PayPal)! So you can unblock that blocked content through VPN!
So if your purpose is only unblocking then there are some good VPNs for you: Turbo VPN, Super VPN, VPN Master, Hola VPN, Secure VPN, Droid VPN etc! And if your purpose is privacy, then these normal VPNs are not for you! This will ruin your privacy! So some good VPNs for you are: HMA VPN, Cyber Ghost VPN, Unseen Online, VPN Hub etc!
And if you are a Cyber Expert or hacker, then the purpose of using your VPN is privacy + secure! Without these two, a hacker is never safe! In this case, if you use the first-line VPN, you will be caught unawares! So some good VPNs for you are Express VPN, Nord VPN, Whoer VPN, Hide.me VPN etc!
So let’s say we need to buy a VPN, or free VPN is enough ??? The answer is very simple if your purpose is unblocking and privacy then free VPNs are enough but free VPN is not at all safe to have privacy + secure! You can be trace at any time, which a hacker would never want! So you must buy a VPN! And now almost all VPN sites can be paid with Bitcoin, Ethereum, Paypal, which almost all of us have!
So far today. Forgive the mistake.
