Hi,
I was reading through the secrets documentation in Python 3.6 and noticed that
it uses /dev/urandom but I'm unsure if that means it'll use a hardware RNG or
just one provided by the operating system (Linux / Windows / etc) in software.
The question is is it possible to determine the source of the randomness from
os.urandom if there was ever a flaw found in a particular hardware RNG? Plus
systems could have a third party hardware RNG that was an external addon card
or similar which might be better than the one found in Intel CPUs.
I'm just a bit curious about the whole "will always use the strongest source
for pseudo-random numbers" when research could change that assumption overnight
based on discovered flaws.
This is probably a really stupid question and if it is I apologise but I'm
somewhat confused.
Thanks for any help.
