Amnezichat

Anti-forensic and secure messenger

Description:

An anti-forensic messenger offers significant benefits by enhancing the privacy and security of digital communications. It is designed to prevent forensic investigators or malicious actors from recovering, analyzing, or tracing messages and related metadata. By employing advanced encryption, secure deletion methods, and obfuscation techniques, these messengers ensure that deleted or hidden communications are nearly impossible to recover.

Features:

• 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 10 minutes

• Tor/I2P routing support

• Docker support

• Built in Rust

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

• Amnezichat Protocol 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
