Struct MlDsa 

pub struct MlDsa;

ML-DSA-87 (NIST FIPS 204, security level 5).

ML-DSA (formerly Dilithium) is a lattice-based signature scheme standardised by NIST. It is the recommended default for most signing applications.

Sizes

Object	Bytes
Public key	2,592
Secret key	4,896
Signature	4,595

Pros

• Compact signatures (~4.5 KB) and fast signing and verification — practical for high-throughput or bandwidth-sensitive applications.
• NIST-standardised (FIPS 204); broad library and hardware support.
• Deterministic signing (no per-signature randomness required).

Cons

• Lattice-based: security depends on Module-LWE/SIS. Strong, but a newer assumption (~10 years) compared to hash-based alternatives.

Implementations

impl MlDsa

pub fn keypair() -> Result<(PublicKey, SecretKey)>

pub fn sign( message: impl AsRef<[u8]>, secret_key: &SecretKey, ) -> Result<Signature>

pub fn verify( message: impl AsRef<[u8]>, signature: &Signature, public_key: &PublicKey, ) -> Result<()>
