Although I must admit I am still confused Ill try to answer. Dk2ReadRandom numbers is just a rng generator. It produces output by 2 arguments, the length of data and the seed of data.
From what I seen it should allow 0-FF seeds and the asic itself can produce "unlimited" data but it does slow down so theres a point where its to slow to consider a security device worth having. Dk2ReadRandomNumbers is the api your looking for, just use that api with dk2id, seed value (this is 0-FF) and u wont need any special developer codes to access this api.
