Onion routing is a technique for anonymous communication over a computer network. In an onion network, messages are encapsulated in layers of encryption, analogous to layers of an onion.

There is a large set of precautionary measures and best practices to make web browsing safer and more secure for users. Let’s say that you send an HTTPs request to a server and someone intercepts that request but that person can’t know what that message says because its encrypted. But you are still not satisfied with this level of security and want to take this to the next level i.e. you don’t even want anyone sniffing on your network to know which server you are contacting and if you are making any requests or not. This is where onion routing comes in.
