Summary

`pqcrypto` is unmaintained: upstream PQClean project being archived

Details

The pqcrypto crate and the entire pqcrypto-* ecosystem wrap 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, algorithm updates, or bug fixes will be applied to the upstream implementations.

As a result, this crate and all dependent crates in the pqcrypto-* ecosystem will no longer receive updates. Users should migrate to actively maintained alternatives. Pure-Rust replacements are available for several algorithms:

ML-KEM (FIPS 203): ml-kem
ML-DSA (FIPS 204): ml-dsa
SLH-DSA (FIPS 205): slh-dsa
FN-DSA (FIPS 206): fn-dsa
