I am majoring in computer science but I have recently become obsessively interested in information theory and cryptography. I have read some articles about entropy and random number generators.
I find few algorithms online to generate 128-bit entropy supported random number generator. As I can tell from other discussion in this website that random number generator does not change the entropy.
It seems that N-bit-entropy-support random number generator only depends on how many bit of initial state supported by the algorithm. If my understanding is correct, I wonder if it is possible to figure out the how many bit of entropy supported by any given random number generator if we don't know the algorithm (like testing it in a black box)?
