# Pqc Signature Auditor

> Audit post-quantum signature implementations — ML-DSA (FIPS 204), SLH-DSA (FIPS 205), FN-DSA/Falcon (pending standardization), and stateful hash signatures XMSS/LMS/HSS (NIST SP 800-208) — for rejection-sampling correctness, hedged/deterministic signing modes, verification bound enforcement, and one-time-signature state management. Use when reviewing PQ signing, verification, or OTS index/state persistence.
