Main Concept

This application attempts to determine the security of a password, in the context of an attack by brute-force methods. That is, assuming a smart cyber-criminal is performing two billion guesses per second with unlimited tries, would it be reasonable for this person to simply guess a password? The difficulty of guessing a password grows exponentially with the number of characters the password has, and how many different types of characters it includes. Passwords which consist of only numbers or only letters are much weaker than those that contain both. It is also better if the password isn't a word found in the dictionary and doesn't contain one as a substring.
