comment Are there any Javascript CSPRNGs?
Your question is not clear: you say you want a CSPRNG, and then you talk about an entropy source. Do you need a CSRNG (unpredictable, i.e. at least seeded with a sufficient entropy source), or a CSPRNG (i.e. deterministic, but predictable only by knowing the secret seed)?

comment AES CTR rekeys rapidly, does this produce patterns?
I'm having trouble following the algorithm description you've posted here. Where does the seed at step 3 come from? In step 10, where does the “at random” come from, is that the one from step 7? (“At random” is intrinsically unclear when you're describing an RNG!) It would be easier to follow if you provided math or pseudocode alongside the English.

I guess you meant if the counter value is repeated, not the “input” (plaintext)? That's true (with the added qualification that it's when that happens with the same key), but not obviously relevant here, since each counter generation happens at the same time as a new key generation.
