pq-crystals/kyber

pq-crystals/kyber is the definition of infrastructure-grade software. It represents the culmination of a decade-long NIST competition to define the next generation of global encryption standards. Its defensibility is near-infinite because it is not just code, but the standardized reference for a mathematical protocol that has undergone intense global peer review. While competitors existed (NTRU, SABER, McEliece), Kyber emerged as the NIST selection for general-purpose encryption. Frontier labs (OpenAI, Google) are consumers of this technology, not competitors; they are currently integrating this exact math into Chrome, Android, and internal communication protocols via libraries like BoringSSL. The quantitative metrics (1,100+ stars, 280+ forks) are extremely high for a niche C-based cryptographic primitive, signaling its status as the 'gold standard' implementation. The only realistic threat to this project is the discovery of a fundamental mathematical flaw in the Module-LWE (Learning With Errors) problem, which is a risk shared by the entire field of lattice-based cryptography, or the eventual transition to a newer standard decades from now.
