summary: "Layered encryption as implemented in Kovri / I2P"

The Basics

@garlic-encryption is @I2P's implementation of @message based @layered-encryption (similar to flow-based Onion-Routing).

By @encrypting @messages in layers, this allows a @message to be routed through a sequence of proxies without allowing the proxies (or any intermediaries) to read the contents of the @message. @Layered-Encryption is a fundamental feature in @Kovri, @I2P, and Tor and is the cornerstone for securing anonymity within these overlay-networks.

In-depth information

For @garlic-encryption, the primary difference between @Kovri/@I2P and Tor is:

• @Kovri/@I2P bundles multiple @messages together to form garlic "cloves"
  • any number of messages can be contained in a "clove" instead of only a single message
• @Kovri/@I2P uses ElGamal/AES @encryption for @messages and @transports
