You wrote "..... or one finds a good, reliable CSPRNG that is already publicly available for one's platform and which has been analysed by the cryptographic community and found to be fit for purpose." But an "analysis by the cryptographic community" that one can rely on can in my conviction only be the algorithm of the CSPRNG, e.g. what one reads in HAC. Software in closed-source is not trustworthy. Software in open-source has risks of the genre of Heartbleed. So one has IMHO to take one's own responsibility to implement oneself an algorithm from e.g. HAC. Is that clear? If you would prefer to let the discussion to be further carred out by Kylheku and me alone, that's certainly ok. However, his last post contained nothing of objective arguments, unfortunately. M. K.
