english: Now, the National Institute of Standards and Technology has a set of guidelines which have some rules of thumb for measuring entropy, but they don't have anything too specific, and the reason they only have rules of thumb is it turns out they don't actually have any good data on passwords.
non_english: Nacionalni institut za standarde i tehnologiju ima niz smernica koje daju neka opšta načela za merenje entropije, ali nemaju ništa previše određeno, a razlog zašto imaju samo opšta načela je to što oni zapravo nemaju  neke kvalitetne podatke o šiframa.
