Quantum computers will break today's encryption. We research what comes next.
Independent assessment of post-quantum cryptography & quantum computing
Learn the basics — from public-key cryptography to quantum threats — in our beginner-friendly guide. No prior knowledge needed.
Start Learning →This new Google white paper sharply lowers the estimated quantum cost of breaking the elliptic-curve cryptography behind Bitcoin and Ethereum, making the post-quantum transition feel much closer—and much more urgent—than many assumed.
Read Abstract →Hybrid TLS key exchange (X25519 + ML-KEM-768) is becoming the first large-scale post-quantum defense on the Internet—this article explains how it works and why it matters.
Read Abstract →Code signing anchors software supply chain security, but current algorithms are quantum-vulnerable. This article explores the rising threat of supply-chain attacks, the transition to ML-DSA, and why migration must begin before 2030.
Read Abstract →NIST’s new post-quantum standards are stable; the hard part is fitting them into constrained devices without fragmentation chaos.
Read Abstract →The quantum threat to blockchain is real, and Bitcoin is not immune. This article explores the risks and potential solutions for preserving the security of your digital assets in a post- quantum world.
Read Abstract →TLS 1.3 uses both key exchange and digital signatures—but the "harvest now, decrypt later" threat only makes one of them an urgent post-quantum priority.
Read Abstract →Experience the difference between classical and post-quantum TLS handshakes. Our interactive simulation shows real performance metrics and size comparisons between traditional cryptography and quantum-safe alternatives.

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.
