What is Onion Routing (TOR)
Hey guyz Learn Hacking is back with something new for you guyz as usual. Today we are going to discuss about Onion Routing.
Well what according to you could it be… ONION ROUTING… sounds new right. Well just read on.
How many of you have ever used proxies on internet for any reason like accessing blocked websites from your school/college/office or just hiding your actual identity from the world of internet. I guess many… But do you actually know how a proxy works. The image below depicts its working clearly.
Thus a proxy server hides our identity by acting as an intermediary between us and the web server that we are accessing. But this is not that anynomous as we think… Why?
Well the answer is pretty simple. There is only one intermediary between us and the world of Internet. Suppose we break into a server using a proxy server thinking that we are anonymous. But what if owner of web server starts enquiring about the clients connecting to it using the proxy server and it is possible that owners of proxy server might reveal our identity. This means we cant actually rely on proxy servers for being anonymous online.
Here comes the concept of THE ONION ROUTING (TOR) into picture. By using this , the client traffic is supposed to be passed from three different servers or nodes before reaching to actual web server. It may randomly take any path through any three nodes.
Lets consider it has taken path shown by green arrows. Now
* Node 1 knows only actual origin(client) but not actual destinantion(web server).
*Node 5 neither knows actual origin nor actual destinantion.
*Node 9 knows actual destination but not actual origin.
Thus no one exactly knows which client is accessing which web server. So it is highly anonymous and secure. Thus it becomes far better than using Proxies. Now the next question that comes in ming is that, How Can We Actually Do That.. the answer is pretty simple.
Installing and Using TOR.
Note: You need to install a Mozilla firefox add on which is included in package you have downloaded to use TOR ( The Onion Routing)
Step 2. Open the ‘Vidalia Control Panel’ from the task bar and Click on ‘Start TOR’
Step3. Now open Mozilla Firefox browser, single click on red highlighted ‘TOR Disabled’ on right corner of browser and it will turn to green highlighted ‘TOR Enabled’.
TIP:-To check if its working properly or not, just go to ‘www.whatismyip.com’ and you will see your new public IP address that will keep changing after an interval of time according to the path randomly taken by web traffic through three different nodes.
