PQCryptography.de offers independent assessment of post-quantum cryptography and quantum computing technologies.
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 →A concise, non-technical explainer that shows why Post-Quantum Cryptography (PQC) should be adopted now as the internet-scale foundation, how Quantum Key Distribution (QKD) complements it on select high-assurance links.
Read Abstract →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 →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.
