Tor and VPNs are two of the most powerful online privacy tools available

What is a VPN?

Virtual Private Network, or VPN, is a technology that protects your privacy when you use the Internet by routing your connection through a server that hides your IP address and encrypts your online communication.

How do VPNs Work?

A VPN consists of a network of servers, typically located in multiple countries around the world. When you use a VPN, information sent from your computer passes through one of the VPN provider’s servers before going to its online destination, such as your online banking account. Similarly, information sent to your computer from outside your network passes through the VPN server before reaching your device.

As a result, you’re able to send and receive data without giving up your online location. The online destination will only see traffic coming from the VPN server, not your device or true location. Additionally, messages sent from the server are encrypted, blocking unwanted access from third parties.

VPN Advantages

Using a VPN to protect your privacy has some big advantages over using an unprotected connection. They are full message encryption, ease to install, usually faster.

Full message encryption


VPNs encrypt all messages passing between their servers and your computer. This prevents anyone (such as your ISP) from spying on your connection and intercepting your data. This is especially important in countries with high levels of censorship, or when you’re sending particularly sensitive data.

VPN Disadvantages

Using a VPN can provide good security against most kinds of surveillance. However, there are ways that your privacy can be know to the provider you use. I suggest not using free one when you use a VPN. You need to check your VPN provider to ensure they are not keep logs and They are using strong encryption such as 256BIT

Tor

Tor provides anonymity.

When you use the Tor network you don’t have to trust anyone. The design of Tor makes you virtually anonymous when you go online. While no system is 100 percent foolproof, it would be exceedingly difficult for anyone to identify you when you use the Tor network.

A VPN is a network of servers that protects your privacy by encrypting your messages and hiding your IP address. Your VPN provider controls both the VPN software on your computer, and the servers in their network. You have to trust your VPN service to protect your privacy when you use their network.

Tor is a network of servers that you communicate with anonymously. No one organization controls both the Tor software on your computer and the individual servers in the network. You don’t need to trust anyone to use Tor safely. As much as anything else, the fact that you don’t need to trust anyone when you use Tor is what makes it distinct from a VPN.

How Does Tor Work?

The Tor network is designed so that no server can know both who you are and what you do. The network consists of thousands of independent servers run by volunteers around the world. Here’s what happens when your computer wants to send a message using the Tor network.

With Tor your computer selects more than one TOR server and the process uses Exit Node which encrypts the message that only it can decrypt. This process and service each encrypt your messages more than one time this is called the guard node and the message is sent. Each server will decrypt the message until it to it final service so no one know who sent it.

This is key to understanding Tor so let’s look at what each server in the path knows.

No one server knows or can know both where the message came from and what it says. This is how Tor provides anonymity.

Tor Onion Routing vs. VPN Encryption

The way messages are routed within their networks is the key difference between VPNs and Tor.

Tor uses Onion Routing, a more complex approach. Onion Routing requires the message to pass through at least three, randomly-selected Tor servers before it gets sent to its final destination. Before the message leaves your computer, the Tor software encrypts the message multiple times. The effect is to give the message layers of encryption that must be peeled, similar to layers of an onion.

As the message passes through the network, each server decrypts one of the layers. When the final server in the path peels away the final layer of encryption, it exposes your original message, and forwards it to its destination outside the Tor network.

As a result of the encryption and the way Tor servers pass messages between each other, none of the servers can know both who sent the message, and what the message says. This makes you anonymous within the network. Tor software in your computer chooses new servers to use approximately every 10 minutes.

Tor Advantages

Using Tor to connect to the Internet offers several advantages over an unprotected connection.

Most Tor servers are run by volunteer privacy advocates. To shut down Tor, you would have to go after each individual server in the network. This makes trying to shut down Tor about as practical as stopping thousands of servers that are independently owned.

Tor Disadvantages

While Tor is a great system for using the Internet anonymously, it isn’t a perfect solution. Here are some disadvantages to using Tor. It can be very slow because of all server you have to connect with and it is run by volunteers who could have old computer or software.

Some different between VPN an TOR. TOR is free and is anonymity while VPN is not completely anonymity and companies are now charging to use VPN’s.

I perfer a VPN that I trust over TOR especially if you are trying to buy something online. With TOR no one know who you are so cannot usually buy somethings. With VPN’s you go straight to your providers server and no one should be able to see what you are doing. This is especially important if you use public Wi-Fi services that anyone can use and see what you are doing
