Tor: The Onion Router and its Hidden Services
We live in a time when everything we do online is watched. Every time we click on something, it is recorded. Every time we search for something, it is written down. The information about what we do online is sold to whoever is willing to pay the most for it. This makes it feel like it is impossible to have any privacy when we are online. It is, like a story that people tell, but it is not real. As we have the Tor browser.
But what is Tor? Well, many people talk about Tor when they talk about hackers and the dark web. But Tor is not just something that is used by these people only. It is a good tool that helps keep people’s online activities private. Many journalists use Tor, activists use Tor, and regular people also use Tor. They all use Tor because they believe that what they do online is their business, and nobody else should even know about it. So, in general, Tor is used by people who think that their online activities should be private.
What is Tor?
Tor is a program that helps people talk to each other on the internet without anyone knowing who they are. It is like a road for your internet to travel on. When you use a browser like Chrome or Safari, it is like sending a postcard. The people who help get the postcard to where it’s going can see who sent it and what it says.
Tor is different from the usual browsers like Google and Bing. It is like putting your message in a lot of envelopes, one inside the other. By the time your message gets to where it’s going, the person who gets it does not know who sent it. The people who help get your internet to where it’s going also do not know what you are looking at.
Tor was made because the people who created it think that being able to keep things private is a basic right that everyone should have. They wanted to make a new way for people to look at the internet without leaving a trail of information about what they’re doing. Tor is like a way to browse the web without leaving any clues behind about what you’re doing. The people who made Tor want to help people use the internet without being tracked.
How Does Tor Work?
The name “The Onion Router” is not just a name; in reality, it is the technology that actually works. The Onion Router works by using something called Onion Routing. When you use the Tor Browser, your information does not go straight from one place to another. It takes a path that goes back and forth through a network of servers that people volunteer to run. These servers are called nodes or relays.
The first stop is the entry node to which your computer is connected. This node knows your computer address. It does not know what you are sending or where you are sending it. Then, it goes to the middle node from which the information is passed to the relay. This node is like a person in the middle who does not know who started it or where it is going; it only knows who gave it the information and who to give it to next. After that, the last stop is called the exit node, which is the part of The Onion Router. In this node, the information is sent to the website you want to visit. The website sees the address of The Exit Node, not your address.
Each time the information jumps from one node to another, it is encrypted again. It is like peeling an onion; each node only looks at the address, it does not look at the whole path. No one node knows the path from you to the website, not even The Tor Browser itself, only that the information is going through The Onion Router.
What Does Tor Do?
Tor is like a shield and a key. The main things Tor does are:
- Hiding Your IP Address: This means it keeps your identity hidden, so websites do not know where you are or what you do on the internet.
- Bypassing Censorship: In some countries, the internet is very restricted. Tor helps people get to news sites and social media that are blocked.
- Preventing Traffic Analysis: even if someone is looking at what you do, on the internet, they cannot see what you are doing; they only know you are using Tor.
- Accessing .onion Sites: Tor is the way to get to the “Tor Hidden Services”; this is a part of the internet that you cannot find with Google Tor is the key to getting to these .onion Sites.
Who Created Tor?
Surprisingly, Tor, the tool that helps people stay online, wasn’t created by a secret group of people in a hidden place. The United States Government actually developed it purposely. In the mid-1990s, mathematicians and computer scientists at the U.S. Naval Research Laboratory, including Paul Syverson, Michael Reed, and David Goldschlag, worked on onion routing.
Their goal was to protect U.S. Intelligence communications. The idea was simple: if only the military used the network, it would be easy to identify. So they needed a network that everyone could use to help keep their agents hidden. In 2002, the project was made a source. Later in 2006, The Tor Project, a non-profit organization, was founded to maintain Tor.
Pros & Cons of Tor
The Pros
Using Tor is a trade-off, and you get a lot of privacy. The internet does not feel as modern. Below, we have mentioned the good things about Tor:
- It really helps to keep you anonymous, and this is probably the best way to hide who you are online.
- It is free to use. You do not have to pay any money to use Tor.
- A lot of people work together to make sure Tor is safe. Because Tor is a source, thousands of experts look at the code to make sure there are no secret ways for people to get in.
- You can usually get to the websites you want. It is very hard for governments to completely block Tor.
The Cons
- Slow Speed: When you use the internet with Tor, it is really slow because your information has to go to three computers all around the world. This makes browsing the internet feel like it did a time ago when we used dial-up.
- Website Breakage: Some websites will not work properly with Tor because they do not like the way Tor works. Tor does not allow some things to happen on websites for safety reasons, so some websites will not load correctly.
- Stigma: Some people think that Tor is bad because it can be used for things. If your internet company or boss sees that you are using Tor, they might get upset with you.
- Exit Node Risks: When you use Tor to visit a website that’s not very safe, the last computer that your information goes through can see what you are doing. This is called the Exit Node. It is a problem because Tor cannot keep your information safe if the website is not using HTTPS.
Is Tor Safe?
Is Tor a safe thing for the internet? Well, the answer is unclear. It is like a really good disguise for your internet activities. When you use Tor, it is like you are wearing a mask. It is a tool that helps you stay anonymous if you know how to use it correctly. The biggest problem comes with Tor when people do not use it correctly. If you use Tor to get a file and then you open that file while you are still on the internet, that file might send your internet address to someone else.
The computer in the chain of computers that makes up the Tor network is called the Exit Node. This node sees all the information that you send through Tor when you are done using the network. If you are looking at a website that is not encrypted, which means it does not have HTTPS in the address, then the person who runs the Exit Node might be able to see what you are doing. They could even see what you are sending to the website. This is a problem because it means that your information is not safe.
You have to be careful when you use Tor and make sure that you are using websites that are encrypted. Tor is like a tunnel that helps you stay safe on the internet. You have to make sure that you are using it correctly.
How to Protect Yourself When Using Tor?
If you’re going to step into the world of onion routing, you need to follow the rules of the road.
- Do not change the size of your browser window because when you do that, you are telling people what your screen resolution is. This is something that people can use to figure out who you are. It is called fingerprinting.
- You should not use torrents because the Tor browser is not meant for sharing files quickly. It is really slow, and some torrent programs do not even use the Tor settings, so they can show your internet address.
- Always make sure the website you are visiting has a picture of a lock on it, which means it is using HTTPS.
- Do not add any plugins to your browser because they can be used to spy on you. Just use what comes with the Tor browser.
- Check the security level of your browser, which is like a slider that says Standard, Safer, or Safest. To be the safest, you should choose the option which means it will not use JavaScript.
What are Tor Hidden Services?
Most of us use websites with names that end in .com, .org, or .net. Some special websites on the Tor network end with .onion. These websites can only be accessed through the Tor network. Their web addresses are usually very long. Have lots of random letters and numbers like vww6ybal4bd7szmgncyruucpgfkq.onion.
The good thing about these websites is that they help keep people anonymous. Some examples of the Tor hidden services are:
- Places where people can report secrets, like SecureDrop. Also, The New York Times and Guardian use tor too.
- Search engines that care about privacy, like the onion version of DuckDuckGo.
- Facebook and the BBC have .onion versions. This way, people in those countries can safely access news and social media.
The Dark Side of Tor
When you are using the Tor network, there are real dangers that you should be aware of.
- The Dark Web is like a place with no rules. If you get scammed, you will not get your money back. There is no one to help you. There are lots of websites that want to steal your Bitcoin.
- You might also see bad things. As there is no one to monitor websites like Google or Facebook. You can easily come across graphic or illegal things if you are not careful about what you click on the Dark Web.
- You can get the wrong software on your computer. If you download something from a website on the Tor network that you do not trust, it is like playing a game where you might get lucky. You might get hurt. The Tor network is not a place to download things from websites that you do not know.
Tor vs. VPN Services: What’s the real Difference?
A VPN keeps your data safe from hackers when you use Wi-Fi. It also hides what you’re doing online from your internet service provider. Tor helps you stay anonymous online. This is useful for people who want to make sure nobody can link what they do online to who they are. Lots of people wonder if they need both a VPN and Tor. So, let’s see the difference between these from a clear chart:
| Features | VPN (Virtual Private Network) | Tor (The Onion Router) |
| Speed | Fast, good for streaming/gaming. | Slow; uses for basic browsing. |
| Trust | You must trust the VPN provider. | No need to trust any single person. |
| Anonymity | High (Multi-layered routing). | Limited (The provider sees IP). |
| Cost | Monthly Fees | Free |
| Ease of Use | Set it and forget | Needs specific browser behavior |

Is Tor Right for You?
Tor is not for everyone. If you only want to watch Netflix from another country, you should use a VPN. If you do not want your internet service provider to know that you like to shop for shoes, you can use Incognito mode or a VPN.
But, if you live in a place where the government watches what you say, or if you are a journalist who needs to keep a source secret. Or if you think that people should be able to use the internet without being watched, then Tor is the best tool you can use.
Tor is a reminder that even when everyone is watching, you can still keep to yourself. It is not perfect. It is not fast, but Tor is very important for people who want to be free on the internet. Just remember, always use Tor, the way to keep your security settings high, and do not try to learn more about Tor than you need to know.
