Pure Rust implementation of the Module-Lattice-Based Key-Encapsulation Mechanism Standard
(formerly known as Kyber) as described in [FIPS 203].

## About

ML-KEM is a cutting-edge post-quantum secure key encapsulation mechanism (KEM). KEMs play a vital
role in modern cryptographic systems by securely exchanging keys between parties, ensuring
confidential communication over insecure channels.

Originally developed as Kyber, ML-KEM inherits the foundation of its predecessor while introducing
refinements and optimizations to enhance its security and efficiency. ML-KEM and Kyber are
intimately related, with ML-KEM representing a refined and evolved version of the original Kyber
algorithm. While Kyber pioneered lattice-based cryptography and provided a reliable framework for
secure key exchange, ML-KEM builds upon this foundation, incorporating advancements in
cryptographic research and addressing potential vulnerabilities.

In summary, ML-KEM stands at the forefront of post-quantum cryptography, offering enhanced security
and efficiency in key encapsulation mechanisms to safeguard sensitive communications in an era where
quantum computers potentially pose a looming threat.
