What is encryption?
Encryption is the quiet engine behind almost all online privacy, including Tor. The concept is simpler than it sounds.
Scrambling with a key
Encryption turns readable data into scrambled nonsense using a mathematical key. Only someone with the right key can turn it back. Without the key, intercepted data is useless gibberish.

Why it powers the dark web
Tor wraps your traffic in multiple layers of encryption so each relay only sees what it needs. And .onion addresses are themselves derived from cryptographic keys. Encryption is what makes the whole system private and self-verifying.
