They are already defined. I think you just want to add something like:


If (key.getAlgorithm().equals("ML-KEM") || key.getAlgorithm().equals("ML-DSA")) {
   return ((NamedParameterSpec) key.getParams()).getName();
}


Not urgent, but useful if one of these algorithms were to weaken or be broken for some reason.
