What Is Onion Routing?

Onion routing is like an advanced form of proxy routing. Instead of routing through a single unprotected server, it uses a network of nodes that constantly encrypt your data packets at every step. Only at the end of this “chain” of onion nodes does your data become decrypted and sent to the final destination. In fact, only this “exit node” has the power to decrypt your message, so no other node can even see what you’re sending.
Due to the multiple layers of encryption, which not-so-coincidentally resemble the layers within an onion, it’s extremely difficult to trace your information back to you as the source when you use onion routing.
