Function keygen 

pub fn keygen<P: Params>(
    rng: &mut dyn CryptoRng,
) -> Result<(Vec<u8>, Vec<u8>), MlDsaError>

Generate an ML-DSA key pair.

Implements Algorithm 1 of FIPS 204 (ML-DSA.KeyGen). Draws 32 random bytes from rng and delegates to keygen_internal.

Returns (pk, sk) as byte vectors.

Errors

Returns MlDsaError::RngFailure if the RNG cannot provide bytes.
