To make web browsing safer and more secure for users, there is a large set of precautionary measures and best practises. Messages in an onion network are encapsulated in layers of encryption, similar to the layers of an onion. Unlike onion routing, an encrypted packet can contain multiple packets (garlic cloves) with different destinations, and the sender is not required to specify a return path for the message. Onion routing is a method of communicating anonymously over a computer network. To be given, the secure packets must be received by routers selected by the sender, in the order provided by the sender. To protect the identity of the sender, messages are encrypted several times with the public keys of selected nodes on the network. It encrypts multiple messages together to make it harder for attackers to analyze traffic. The fundamentals of garlic routing and garlic encryption were developed by Michael Freedman and were improved and implemented by the developers of the I2P project. Garlic Routing is a variant of Onion Routing which I2P (Invisible Internet Project) uses.
