# 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`).
