Ah yes... you are right.. sorry, made a mistake in my code.

Random.org's solution is to take a commercial quality radio (i.e. not great
signal, not low noise) tune it to a frequency where there is no station
(they hope it stays that way) and capture noise. The simple coin-flip
corrector scheme, although doing a great job at fixing the bias, tends to
leave residual correlations.
Fourmilab.ch's solution is just a receiver on a much greater frequency!
Does anyone know what additional post processing they do to either whiten
the data or improve the actual entropy?
Thus for either solution I would assume a fairly low entropy content and
then entropy compress the data aggressively before using it.
Finally, for both solutions, the main concern I would have would be whether
someone diverted my data download to some static site with no entropy. Does
anyone know if they sign their bits?

I would be EXTREMELY surprised if the nationality of the submitters was a
factor in NIST's decision. For one, there is no need and for two, if it ever
leaked, it would be very embarrassing.

I know a part of the permanent key and would like to find the rest.
The key is used to hide IP packets content, it just combined with
data by XOR operation. As far as I know the beginning of each packet
I could find the beginning of the key.
I tried to find all the key in the executable and than in core dump.
But seems like it's not a predefined sequence but some hash(?)
function.
So, the question is, which function might generate the following
sequence:
160, 112, 205, 2, 44, 135, 43, 214, 190, 149, 184, 170, 68, 209,
163, 245, 37, 153, 2, 30, 179, etc. (64 known values)
Is there any software to dig up such sequences?
Thanks a lot.
