Module dilithium 

Constants for Module-Lattice-Based Digital Signature Algorithm (ML-DSA)

This module implements the parameter sets defined in FIPS 204 (August 2024) “Module-Lattice-Based Digital Signature Standard” https://doi.org/10.6028/NIST.FIPS.204

All constants in this file are taken directly from the final FIPS 204 standard, NOT from earlier CRYSTALS-Dilithium submissions or draft specifications.
