Quantum-secure encrypted messaging with ML-KEM-768. Future-proof your privacy
Post Quantum Secure Chat — description
The world's first mobile messenger with true Post-Quantum Cryptography.
While current encryption can be broken by future quantum computers, PQC Chat uses ML-KEM-768 and ML-DSA-65 — the same algorithms standardized by NIST for the quantum era.
