Hi there,

part of text from our website:

"Prime numbers have patterns and rules, maybe NSA uses that for making hash functions with "tunnel" (making (bits rotate, bits shift, bits xor and add input) function which dont break rule in every iteration). Tunel is rule which can, for specific output in hash function, predicts field of possible inputs or field of impossible inputs (like Beal conjecture) and dramatically reduce speed of brute force attack. Theoretically, this is possible only if NSA knows secret (unpublished) rules similar to Beal conjecture etc, (Why NSA everytime uses primes for making hash functions?  )''

What do you think about this?
