MLDSA44

ML-DSA-44 (Module-Lattice-Based Digital Signature Algorithm, 44 parameter set) as specified in NIST FIPS 204.

This is a post-quantum signature scheme providing NIST security category 2, which is roughly equivalent to the security of SHA-256 or AES-128.

Key sizes:

Public key: 1312 bytes
Secret key: 2560 bytes
Signature: 2420 bytes

Example usage:

const kp = MLDSA44.KeyPair.generate();
const msg = "Hello, post-quantum world!";
const sig = try kp.sign(msg, null);
try sig.verify(msg, kp.public_key);
