Seems surprising that the number hasn't been calculated exactly. I'd have guessed it's a mechanically solvable but tedious combinatorics problem, but obviously not.

#3Someone have claimed that this is broken: https://github.com/Sc00bz/break-uheprng
The first criticism, while valid, is an anachronism as there wasn't Web Crypto when this RNG was written. The other criticisms are fully valid though and should at least make everyone do a double take whether this is fine for their needs or not.

#4Something about using a PRNG with a large internal state just to generate an output in a large space of possibilities feels wrong to me. If you have enough entropy to fill a high entropy RNG, why not use all that entropy to generate the output in the first place?
Also I'm curious how they generate the latin squares, their claims require a uniform distribution of some kind, which is interesting.

What's wrong with Shieldsup? My experience is that it works perfectly fine.

I still use the DNS speed finder.

#8Sorry to belabor something lots of readers already know: The long key may (or may not) be packed with entropy. But a pseudo-random number generator at best preserves the entropy in the key.

Very well put and worth reinforcing by thinking of PRNGs as entropy reduction functions on the original seeds, that ideally loose as little entropy as possible per generation cycle.

#10Can someone explain to me the value of this? Like, is there value in the "pseudo" that you don't get from a "real" one?
Like, I'm thinking of e.g. the Cloudflare lava lamp thing, and like, isn't that better in every way?
