Protected Against Tomorrow's Threats
While other apps scramble to upgrade their security for the quantum era, Qu-Chat is already quantum-safe with NIST-standardized cryptography.
The Quantum Threat is Real
Within the next decade, quantum computers will be powerful enough to break the encryption used by WhatsApp, Signal, Telegram, and virtually every messaging app today.
Adversaries are already harvesting encrypted communications today with the plan to decrypt them later—a strategy called "harvest now, decrypt later".
If your messages are encrypted with traditional cryptography, they're vulnerable.
Military-Grade Cryptography
ML-KEM-768
(CRYSTALS-Kyber)
NIST-standardized quantum-resistant key encapsulation mechanism. Used for securely exchanging encryption keys between you and your conversation partners.
AES-256-GCM
Symmetric Encryption
The gold standard for symmetric encryption. Used to encrypt your actual message content with keys derived from quantum-safe key exchange.

What We Guarantee
No One Can Read Your Messages
Not us, not hackers, not governments, not even future quantum computers.
No Central Point of Failure
Decentralized architecture means no servers to hack or shut down.
Your Keys, Your Data
Private keys never leave your device. Only you control your conversations.
Standardized & Auditable
NIST-approved algorithms that have been thoroughly vetted by the global cryptography community.
Future-Proof Cryptography
NIST-standardized algorithms designed to withstand quantum attacks.
No Metadata Collection
We don't track who you talk to, when, or for how long.
Our Commitment to Security Standards
We believe security through obscurity is no security at all. That's why:
- ✓We use only NIST-approved cryptographic standards
- ✓We document our encryption implementation in detail
- ✓Our cryptography follows industry best practices
- ✓We prioritize transparency in our security architecture
Experience Quantum-Safe Security
Your messages deserve military-grade protection.
