# Amnezichat

<img src="banner.png" width="1200">

## Anti-forensic and secure messenger
<!-- DESCRIPTION -->
## Description:

Amnezichat offers a highly secure and privacy-focused messaging experience by ensuring that no logs are retained and all message data is stored exclusively in the server's RAM. This approach significantly enhances user privacy because RAM storage is inherently volatile data is automatically erased when the server is powered down or restarted, leaving no trace of already end-to-end encrypted past communications.

<!-- FEATURES -->
## Features:

- Client-side quantum-resistant E2E message encryption

- Forward and backward secrecy for one-to-one chats

- Group chat support using PSK (pre-shared-key)

- Server runs even on cheapest hardware

- Each message is stored encrypted in server's RAM and wiped after 24 hours

- All traffic is routed over Tor/I2P network by default

- Docker support

- Built in Rust

## Comparison chart with other messengers:

## Technical details:

- Defense against AI-guided Traffic Analysis (DAITA) by sending encrypted dummy data at random intervals and padding all messages to a fixed length except files

![packet_capture](packet_capture.png)

- [Amnezichat Protocol](PROTOCOL.md) for end-to-end encryption
- Stores identity keys in local storage encrypted with ChaCha20-Poly1305 and Argon2id KDF with an user specified password

### Amnezichat Protocol:
- EdDSA and Dilithium5 for authentication, ECDH and Kyber1024 for key exchange, encryption using ChaCha20-Poly1305
