Strong Passwords Need Entropy is entropy calculator, password’s strength and survivability checker and a strong password generator. The program analyzes your password and displays statistics about its length, character frequency, symbols, lowercase+uppercase letters, and digits. Based on this information, it calculates the password entropy, or the number of trials needed to find it and the time to crack the password.
Note that this analysis doesn’t take into account “dictionary attacks” or use of words. For example, “ambassadorconjure” is long but not necessarily hard for a computer to guess.
