Struct SoftwareMlDsa65Signer 

pub struct SoftwareMlDsa65Signer { /* private fields */ }

Software-only ML-DSA 65 signer (NIST FIPS 204, security category 3). Wraps the ml-dsa crate’s SigningKey<MlDsa65>. Debug redacts the signing key — only the verifying key bytes appear in Debug.

Key material is in-memory only — never serialize the signing key (process protection guide: docs/pqc-software-only.md).

Implementations

impl SoftwareMlDsa65Signer

pub fn from_seed(seed: [u8; 32]) -> Self

Construct a signer deterministically from a 32-byte seed. FIPS 204 ML-DSA.KeyGen_internal — same seed yields same key pair.

Trait Implementations

impl Debug for SoftwareMlDsa65Signer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PqcSigner for SoftwareMlDsa65Signer

fn sign(&self, msg: &[u8]) -> Result<Vec<u8>, PqcSignError>

Sign msg and return the canonical encoded signature bytes. For ML-DSA 65 this is exactly 3309 bytes (FIPS 204 §4).

fn verifying_key_bytes(&self) -> Vec<u8>

Encoded verifying-key bytes for header pinning. For ML-DSA 65 this is exactly 1952 bytes (FIPS 204 §4).
