This is a small collection of C or C++ files to simulate or test some cases just to proof something.
This program fill "rounds" times a 32 bytes buffer (256 bits) with random data
from /dev/urandom in each round the program count the amount of bit that are in
1 or ON inside the buffer.
The output is the sumary of times that each number of bit was filled and its
percentage value.
In general the amount of times that the program fill 128 bits in 1 is near of
the 5% The other bits are also near of that percentage but in a decending way.
random output:
1 times 89 bits in 1, this is 0.000001

This program fill "rounds" times a 32 bytes buffer (256 bits) with random data from the RNG of libgmp in each round the program count the size in bits that are needed for each number The output is the sumary of times that each number landing in some bit range and its percentage. In general the amount of times that the key lands in 256 bits is near of the 50% all decrementing bits are the half of the previous value
