By the way, thanks Thomas... I've always enjoyed and benefitted from your "CSPRNGs are essentially a stream cipher, and now you finally also understand what a stream cipher really is" explanations on HN over the years. I remember the first time I grokked it from one of your comments, and it was much clearer than anything I could find on Cryptography Stack Exchange (yes, I know!). Since then, I've used the AES-CTR trick for non-critical random generators for many user space fuzz test harnesses, and it's helped speed them up while also being stronger than a PRNG, without a repeating period.
