Privacy Encrypted Messenger

The Privacy Encrypted Messenger provides secure, metadata-resistant off-chain communication. Messages are end-to-end encrypted with ephemeral key exchange, and metadata obfuscation techniques prevent traffic analysis. Core technical components:

• Ephemeral Key Exchange: Uses Diffie–Hellman key agreement with per-message key rotation.

• Metadata Hiding: Implements batch routing, cover traffic, and uniform packet sizing to thwart timing and size correlation attacks.

• Decentralized Relay Network: Message relays operate in a peer-to-peer mesh with reputation-based routing to avoid single points of failure.

• Integration SDK: JavaScript and Rust libraries for embedding secure chat in web and mobile clients.
