Struct MlDsaSignature 

pub struct MlDsaSignature { /* private fields */ }

ML-DSA signature

A quantum-resistant digital signature produced by ML-DSA. Signatures are non-deterministic (include randomness) for enhanced security.

Size Requirements

• ML-DSA-44: 2420 bytes
• ML-DSA-65: 3309 bytes
• ML-DSA-87: 4627 bytes

Examples

use saorsa_pqc::api::sig::{ml_dsa_65, MlDsaSignature, MlDsaVariant};

let dsa = ml_dsa_65();
let (public_key, secret_key) = dsa.generate_keypair()?;

// Create signature
let message = b"Document to sign";
let signature = dsa.sign(&secret_key, message)?;

// Serialize for transmission
let sig_bytes = signature.to_bytes();
assert_eq!(sig_bytes.len(), 3309); // ML-DSA-65 signature size

// Deserialize received signature
let received_sig = MlDsaSignature::from_bytes(MlDsaVariant::MlDsa65, &sig_bytes)?;

// Verify
assert!(dsa.verify(&public_key, message, &received_sig)?);

Implementations

impl MlDsaSignature

pub const fn variant(&self) -> MlDsaVariant

Get the variant of this signature

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

Export the signature as bytes

pub fn from_bytes( variant: MlDsaVariant, bytes: &[u8], ) -> Result<MlDsaSignature, PqcError>

Import a signature from bytes

Errors

Returns an error if the byte slice has an incorrect length for the specified variant.

Trait Implementations

impl Clone for MlDsaSignature

fn clone(&self) -> MlDsaSignature

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Drop for MlDsaSignature

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for MlDsaSignature

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
