Open Source · Tor-Powered · Zero Metadata

Peer-to-peer group chat that routes all traffic through the Tor network.
No accounts. No logs. No persistent keys. When the session ends, nothing remains.

Core Features

Built for Privacy by Design

Every architectural decision in Haze is made to protect your identity and communications.

Zero Identity

No usernames stored, no accounts, no registration. Your identity exists only for the duration of a session.

Tor-Only Transport

All traffic enters and exits through the Tor network via ephemeral hidden services. Your IP is never revealed.

End-to-End Encryption

X25519 ECDH key exchange, ChaCha20-Poly1305 cipher, HKDF-SHA256 key derivation with per-message nonces.

Ephemeral Sessions

Session keys are generated fresh each run and never written to disk. When the session ends, nothing persists.

Panic Button

One click wipes session keys, terminates all connections, and forces immediate exit via os._exit(0) — bypassing all cleanup handlers.

Multi-Language

English and Turkish interface support. Native desktop UI with animated Tor circuit visualizer.

Architecture

How Haze Works

Anonymous peer-to-peer communication through layered encryption and Tor routing.

Client A
Tor Circuit
Encrypted + Anonymous
Host .onion hidden service
Tor Circuit
Encrypted + Anonymous
Client B
01

Host Starts a Session

The host launches a Tor ephemeral hidden service. A .onion address appears in the title bar — share it through a separate secure channel.

02

ECDH Handshake

Each client performs a one-pass X25519 key exchange. The session key is wrapped under a per-connection derived key — plaintext keys never appear on the wire.

03

Encrypted Messages

All messages are encrypted with ChaCha20-Poly1305 using per-message random 12-byte nonces and framed with a 4-byte length prefix.

04

Session Ends, Nothing Remains

When the session ends, the ephemeral hidden service is removed, keys are wiped, and the Tor data directory is deleted. No trace.

Security Model

Every Layer Hardened

A rigorous security model with cryptographic guarantees at each level.
