    Description copied from class: Parameters
    
    Returns true if a key created with the parameters in this object has to have a certain ID when it is in a keyset.
    In Tink, certain keys change their behavior depending on the key id (for example, an Aead object can prefix the ciphertext with the big endian encoding of the key id). If this is the case, such a key should require a unique id in Key.getIdRequirementOrNull() and return true here.
