RustCrypto: ML-KEM
Pure Rust implementation of the Module-Lattice-Based Key-Encapsulation Mechanism Standard (formerly known as Kyber) as described in FIPS 203 (final).
About
ML-KEM is an algorithm which uses public-key cryptography to securely transfer a symmetric key between two parties who want to establish encrypted communications with each other. It uses algorithms which resist potential attacks by hypothetical future quantum computers which, when such computers are sufficiently mature, pose a problem for the algorithms we typically use for secure key establishment using public-key cryptography such as (EC)DH and RSA key encipherment.
Originally developed as CRYSTALS-Kyber (a.k.a. "Kyber"), ML-KEM is a refinement of the original Kyber algorithm after it was selected for standardization by NIST's Post-Quantum Cryptography (PQC) competition. The Kyber algorithm received considerable feedback as part of the standardization process and as such, ML-KEM includes many changes from the original Kyber. It can be though of as the official successor of Kyber.
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.
Features
The following features are provided by this crate:
zeroize— Enables memory zeroing for all cryptographic secretspkcs8— Enables PKCS#8 encoding/decoding traits for encapsulation and decapsulation key typesalloc— Enables allocating PKCS#8 encoding functionspem— Enables PEM encoding/decoding support for PKCS#8 keyshazmat— EnablesEncapsulationKey::encapsulate_deterministic. Useful for testing purposes. Do NOT enable unless you know what you are doing.
The default features are [] (nothing).
