Read the original article Hit count: 234

On the NIST website, there is a tool called sts (Statistical Test Suite) that allow us to rest the validity of a pseudo-random number generator based on a stream of bits in input.

When running the program, there is two variables I am not sure to understand : the stream length and number of bitstream.

Is the stream length the size of the file ? The number of bit inside ? The size of a bitstream ?

Are the bitstreams subset of the whole file ? Chosen how ?

Let say I have a text file containing 1,000,000 bits in ascii. What should be my arguments ?

You can find the user manual here if needed (I didn't find explanation about what are these variables in it).

Thank you
