PQCryptography.de offers independent assessment of post-quantum cryptography and quantum computing technologies.
This article explains why TLS 1.3 is vulnerable to “harvest-now, decrypt-later” attacks—and how the hybrid ML-KEM-768 + X25519 key exchange delivers quantum resilience today while RSA remains sufficient for authentication.
Read Abstract →This playbook distills the BSI’s latest quantum-safe cryptography guidance into three phased actions for German GmbHs, tying in NIS2 compliance triggers and pointing out federal funding to reduce migration costs.
Read Abstract →From browsers to mainframes, post-quantum cryptography is already safeguarding production traffic—and regulators worldwide are turning it into a hard requirement.

PQCryptography.de is built by Dr. Chen, PhD in Quantum Information and Quantum Cryptography, with years of hands-on experience in QKD, quantum computing, and post-quantum cryptography. Our expertise combines deep mathematical foundations with practical knowledge of quantum algorithms (Shor's, Grover's), classical cryptosystems (RSA, ECC), and their post-quantum successors—bridging theoretical quantum security with real-world implementation challenges.
