Struct MlDsaSigner 

pub struct MlDsaSigner { /* private fields */ }

Available on crate features signatures and ml-dsa only.

ML-DSA-65 signer.

Uses the FIPS-204 ML-DSA-65 parameter set for post-quantum digital signatures.

Key Format

Keys are represented as 32-byte seeds. A seed deterministically derives both the signing and verifying keys via ML-DSA.KeyGen_internal (FIPS 204).

Implementations

impl MlDsaSigner

pub fn from_bytes(seed_bytes: &[u8], signer_info: SignerInfo) -> Result<Self>

Create a signer from a 32-byte seed.

The seed deterministically derives the full signing and verifying keys.

Arguments

• seed_bytes - The 32-byte seed
• signer_info - Information about the signer

Errors

Returns an error if the seed is not exactly 32 bytes.

pub fn generate(signer_info: SignerInfo) -> Result<(Self, Vec<u8>)>

Generate a new random ML-DSA-65 key pair.

Returns the signer and the encoded public (verifying) key bytes.

Errors

Returns an error if key generation fails.

pub fn public_key_bytes(&self) -> Vec<u8>

Get the public (verifying) key bytes.

pub fn secret_key_bytes(&self) -> Vec<u8>

Get the secret key seed (32 bytes).

Security Warning

Handle seed bytes with care. Do not log or expose them.
