`pqcrypto-mlkem` is unmaintained: upstream PQClean project being archived
This crate provides Rust bindings to ML-KEM (FIPS 203) via C implementations from PQClean. The PQClean project is being archived in or after July 2026 (see PQClean/PQClean#604), after which no further security patches or bug fixes will be applied to the upstream implementations.
As a result, this crate will no longer receive updates. Users should migrate
to the ml-kem crate, which provides a
pure-Rust implementation of ML-KEM (FIPS 203).
