kyber-nz: ML-KEM (FIPS 203) in Rust

kyber-nz is a pure Rust implementation of the FIPS 203 (Module-Lattice-Based Key-Encapsulation Mechanism) standard, formerly known as CRYSTALS-Kyber.

This project aims to provide a readable, modular, and compliant implementation of the NIST specifications for post-quantum cryptography.

📦 Features

• FIPS 203 Compliance: Faithfully implements the algorithms specified in the official standard.
• Full Security Level Support:
  • ML-KEM-512
  • ML-KEM-768
  • ML-KEM-1024
• Pure Rust: No C dependencies, ensuring memory safety and portability.
• Integer Arithmetic: No floating-point operations, guaranteeing reproducibility across all architectures.
• Modular Architecture: Clear separation between arithmetic layers (polynomial), encryption (pke), and encapsulation (kem).
