WebMay 23, 2024 · Chi-square test cannot prove that a random number generator is cryptographically secure. All it can do is show that the RNG is not subject to certain types of biases — but this is not even sufficient to show that it's a good PRNG, let alone that it's secure! – user149341 Apr 12, 2013 at 0:02 Add a comment Your Answer Post Your Answer WebCryptographically secure hashes usually work on bitstrings of arbitrary length and output a fixed length bitstring.
