Module mldsa 

ML-DSA

ML-DSA is a post-quantum key signature scheme, specified in FIPS 204.

use bssl_crypto::mldsa;

// Generate a key pair.
let (serialized_public_key, private_key, _private_seed) = mldsa::PrivateKey65::generate();

// Send `serialized_public_key` to the verifier. The verifier parses it:
let public_key = mldsa::PublicKey65::parse(&serialized_public_key).unwrap();

// The signer signs a message.
let message = &[0u8, 1, 2, 3];
let signature = private_key.sign(message);

// Send `message` and `signature` to the verifier. The verifier checks the signature.
assert!(public_key.verify(message, &signature).is_ok());
