The program analyzes your password and displays its length, the character frequency and the number of symbols, lowercase and uppercase letters and digits. Based on this information, it calculates the password entropy, the number of trials needed to find it and the time to crack the password. You can also verify if your password is in the list of '10,000 Worst passwords'.
