🎯 About This Experiment

This subdomain (pqc.pqcrypta.com) demonstrates pure post-quantum cryptography in action. Unlike traditional TLS which uses RSA or ECDSA, this site uses ML-DSA-87 (Module-Lattice Digital Signature Algorithm) for certificate signatures—a NIST-standardized quantum-resistant algorithm.

Certificate Signature ML-DSA-87 (NIST Post-Quantum Standard)
Key Exchange ML-KEM-1024 Capable (Hybrid Mode)
Encryption AES-256-GCM
Security Level NIST Level 5 (Highest)

💡 Why Post-Quantum Cryptography Matters

Quantum computers threaten current encryption methods. RSA and ECDSA can be broken by Shor's algorithm on a sufficiently powerful quantum computer. Post-quantum cryptography uses mathematical problems that remain hard even for quantum computers:

This site proves that quantum-resistant TLS is not just theoretical—it works today, providing protection against future quantum threats.
