`pqcrypto-sphincsplus` is unmaintained: upstream PQClean project being archived
This crate provides Rust bindings to SPHINCS+/SLH-DSA (FIPS 205) 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 slh-dsa crate, which provides a
pure-Rust implementation of SLH-DSA (FIPS 205).
