Hi All,
Does anyone have any good reccomendations for tools or process testing to find
good RNG entropy? Is Diehard still a thing, (Dieharder?)
Context:
I recall quite some years back, folks here testing some hardware RNG's with me.
On a lark, a hardware person I know just whipped up some hardware RNG
prototypes, still playing with them, (usb thingies spewing bits).
Anyhow, it's been a while, and I'm interested in testing and test methodology,
but can't for the life of me remember how we tested quality of entropy before.
Thanks!
Best,

Note, while you can prove that a HW RNG isn't totally busted,
short fo reverse engnieering it with an electron microscope,
you can't prove it's not backdoored.
Noted!
The thing I find useful about this one, the person making it is just soldering
one together with parts they have lying around (on a lark). Even a knucklehead
like me can visually inspect the circuit.
A PIC chip is dumping to serial, perhaps that's the one tricky thing to
validate?
I'll let em' finish and get it working before going into that fun :)
keep us updated - sounds like a fun project! it makes me wonder how i
could pair something like this with my new flipper zero the missus got
me for the holidays.
