Updated my random number stream generator web toy.
Now using a freshly modified entropy collection method that doesn't totally crash Tor Browser and other runtime environments that have a generally lower time accuracy. Also now using ChaCha20 insteal of Salsa20.

To my surprise, this thing is actually working incredibly well for how I am abusing timers and OS task scheduler process interrupts in order to gather entropy for a reasonably random number source.

I've been experimenting with these types of tricks for a while. Maybe I will build it up into a proper -- somewhat cryptographically secure -- mixed random number pool source. I will have to look into how people go about doing that I guess.

Oh, well then, never mind, the *account* still works.

Fug.
