Enum MLDSA 

#[repr(u32)]
pub enum MLDSA {
    MLDSA44 = 2,
    MLDSA65 = 3,
    MLDSA87 = 5,
}

Security levels for the ML-DSA post-quantum digital signature algorithm.

ML-DSA (Module Lattice-based Digital Signature Algorithm) is a post-quantum digital signature algorithm standardized by NIST. It provides resistance against attacks from both classical and quantum computers.

Each security level offers different trade-offs between security, performance, and key/signature sizes:

• MLDSA44: NIST security level 2 (roughly equivalent to AES-128)
• MLDSA65: NIST security level 3 (roughly equivalent to AES-192)
• MLDSA87: NIST security level 5 (roughly equivalent to AES-256)

The numeric values (2, 3, 5) correspond to the NIST security levels and are used in CBOR serialization.

Variants

MLDSA44 = 2

ML-DSA Level 2 (NIST security level 2, roughly equivalent to AES-128)

MLDSA65 = 3

ML-DSA Level 3 (NIST security level 3, roughly equivalent to AES-192)

MLDSA87 = 5

ML-DSA Level 5 (NIST security level 5, roughly equivalent to AES-256)

Implementations

impl MLDSA

pub fn keypair(self) -> (MLDSAPrivateKey, MLDSAPublicKey)

Generates a new ML-DSA keypair with the specified security level.

Returns

A tuple containing the private key and public key.

Examples

use bc_components::MLDSA;

let (private_key, public_key) = MLDSA::MLDSA44.keypair();

pub fn private_key_size(&self) -> usize

Returns the size of a private key in bytes for this security level.

pub fn public_key_size(&self) -> usize

Returns the size of a public key in bytes for this security level.

pub fn signature_size(&self) -> usize

Returns the size of a signature in bytes for this security level.

Trait Implementations

impl Clone for MLDSA

fn clone(&self) -> MLDSA

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MLDSA

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

Formats the value using the given formatter.

impl From<MLDSA> for CBOR

Converts an MLDSA value to CBOR.

fn from(level: MLDSA) -> Self

Converts to the numeric security level value (2, 3, or 5).

impl Hash for MLDSA

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MLDSA

fn eq(&self, other: &MLDSA) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<CBOR> for MLDSA

Attempts to convert CBOR to an MLDSA value.

fn try_from(cbor: CBOR) -> Result<Self>

Converts from a CBOR-encoded security level (2, 3, or 5).

Errors

Returns an error if the CBOR value doesn’t represent a valid ML-DSA level.

type Error = Error

The type returned in the event of a conversion error.
