About Encryptorium

What Encryptorium is

Encryptorium is an independent applied cryptography research platform. We produce original research, technical analysis, and open resources focused on post-quantum cryptography and post-quantum zero-knowledge proof systems. Our work is grounded in established PQC standards and guidance: NIST, IETF post-quantum and hybrid TLS standardization, NCSC, and CycloneDX CBOM.

We are not a cybersecurity vendor and we do not sell products. Encryptorium exists to publish research, track standards, and provide practitioners with the analysis they need for the quantum transition. Our focus is on PQC migration as an architectural and lifecycle problem, not just an algorithm swap. We also offer advisory services for organizations planning that work.

Who

Encryptorium is founded and run by Andreas Renz (@0xLoopTheory), a cryptologist and cybersecurity researcher based in Switzerland. He holds an MSc in Business IT from ZHAW and is CISSP certified.

His peer-reviewed work is in usable security: two first-author papers on the user experience of smart speaker authentication, published at Mensch und Computer 2022 and in i-com. That work is not cryptography. His current work is on deployed post-quantum cryptography, including a systematization of knowledge on the post-quantum security of zero-knowledge proof systems (see research, DOI 10.5281/zenodo.21425310). That report is self-published and has not been peer reviewed.

Publication record: ORCID and dblp.

What we cover

• PQC migration analysis: Standards tracking, adoption measurement, cryptographic inventory methods, and migration guidance aligned to NIST FIPS 203/204/205, NCSC's 2028/2031/2035 migration milestones, and CycloneDX CBOM — all under the harvest-now-decrypt-later (HNDL) threat model.
• Post-quantum ZK: Security analysis of deployed zero-knowledge proof systems under quantum threat models. See our research.
• Standards tracking: NIST, NCSC UK, ETSI, and IETF standardization progress. See the PQC timeline.
• Open resources: Free assessment methodology, curated reference library, and open-source tooling.

The book

The Encryptorium Book of Post-Quantum Cryptography is a practitioner's book in seven parts, running from the quantum threat model through lattice-based, hash-based, code-based, and isogeny-based constructions to migration, deployment, and post-quantum zero knowledge. Forty-one chapters, 281 verified code blocks, 301 cited sources. The ML-KEM, ML-DSA, and SLH-DSA implementations are built from scratch and checked against the official NIST vectors; the code-based and isogeny-based builds are pedagogical, and each chapter states how its code differs from the scheme it models. It is free to read at book.encryptorium.com, with the prose under CC BY-SA 4.0.

Fiction

Andreas Renz also writes fiction under his own byline. His debut novel, Cleartext, is a near-future techno-thriller about post-quantum cryptography and institutional oversight. Available now in paperback and ebook. More at cleartextnovel.com.
