Entropis

Quantum computers will soon break the encryption protecting every password and message sent today. Entropis makes post-quantum cryptography accessible — a web studio and public API that encrypts data using ML-KEM-768 (FIPS 203) and AES-256-GCM, hardened by a 40-stage key derivation function built on Ramanujan tau functions, Riemann zeta, and 38 other number-theoretic algorithms. We built the entire math layer from scratch in JavaScript — 19 modules, 40 functions, verified against 51 invariant tests — with a Next.js frontend featuring interactive 4D tesseract visualizations and a Node.js backend deployed on Render. The biggest challenges were getting the math right at BigInt precision, debugging token lifecycle issues across OAuth and anonymous sessions, and bridging the gap between localhost and production across three different origins.
