Secure messaging for the quantum era. PQC Chat is the first consumer messaging app built with NIST-standardized post-quantum cryptography. While traditional encryption may be vulnerable to future quantum computers, PQC Chat uses ML-KEM-768 and ML-DSA-44 algorithms to ensure your private conversations remain private — today and tomorrow. Why Post-Quantum Security Matters Quantum computers pose a real threat to current encryption standards. Data encrypted today could be stored and decrypted later when quantum computers become powerful enough. PQC Chat protects you against this "harvest now, decrypt later" threat. Key Features • True End-to-End Encryption — Messages are encrypted on your device and can only be read by the intended recipient. Not even we can access your conversations. • NIST-Approved Algorithms — Built with ML-KEM-768 for key exchange and ML-DSA-44 for digital signatures, the same standards adopted by governments worldwide. • Secure Image Sharing — Photos are encrypted before leaving your device, ensuring complete privacy for all shared media. • QR Code Contact Verification — Verify contacts in person by scanning QR codes, preventing man-in-the-middle attacks. • Real-Time Messaging — Instant message delivery with read receipts and typing indicators. • No Phone Number Required — Create an account without sharing personal information. • Cross-Platform — Message friends on any device seamlessly. Privacy by Design - No message content stored on servers - No tracking or analytics - No ads, ever - Open cryptographic standards About Post-Quantum Cryptography PQC Chat implements the Federal Information Processing Standards (FIPS) 203 and 204, published by the National Institute of Standards and Technology (NIST) in August 2024. These represent the gold standard in quantum-resistant cryptography. Protect your conversations for the future. Download PQC Chat today. Terms of Use (EULA): https://pqcnow.com/terms-of-service
