# Signature Scheme Auditor

> Audit classical signature schemes — generic ECDSA across curves, Schnorr/ BIP-340, EdDSA/Ed25519, RSA-PSS and PKCS#1 v1.5 — for verification-equation correctness, malleability, canonical encoding, public-key validation, and hash/prehash semantics. Use for standalone signature library review outside Ethereum application encoding, BLS, or threshold protocols.
