write a program to perform password strength analysis by looking up a password in a common password table and/or calculating its strength rating by cakulating the “entropy” of a password.

INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

Hello, I need help creating a computer program that will test the strength of a password a user inputs. This program should be written in basic C++ language. All requirements will be attached.

Objective:

We have learned the basic C++ features needed to write structured programs so we can begin to focus more on program design and problem solution. The object of this assignment is to analyze a problem, design a sokition. then write a program to solve it. You are to design and

write a program to perform password strength analysis by looking up a password in a common password table and/or calculating its strength rating by cakulating the “entropy” of a password.

Instructions:

1. Ask the user to enter any password to have its strength checked.

A. If the user enters quit’ exit the program.

B. If the user presses enter with an empty line, ask for the password again.

2. Make sure the entered password is not in a list of common passwords.

A. The common password list is in a file named commonsswo,ds.dat ,. Do not ask the user to enter this (iJuawne..xode ¡t kto 

WARN ING: The common password list is built from reaNife password data and contains profana y, so if that would offend you do not visually examine the passwords in the list and do not enter profanity as passwords to test the program

B. The first entry In the common password file is the number of elements in the list.

C. You are to read this number from the file, then dynamically allocate a common password array to exactly the right size.

D. Read the data from the file into the array then close the file.

3. If the password is in the list, display its position in the list and reject it because it is a common password.

4. For passwords that are not rejected in the previous step:

A. CalcuLate the entropy of the password using the formula below.

B. Output the password strength rating based on its entropy using the Strength Rating table below,

5. For this program we will assume that passwords can consist of lower case, upper case, digits and special characters.

Challenge (optional):

If the user presses ‘enter’ with an empty line, randomly generate and display a “Strong” passwGrd (Entropy>. 60 but <128). then calculate and output the actual entropy of the password.

Entropy Formula:

E =  or Iog2(R”)

L = the length of the password”

R = the sum of the character pools represented in the password according to the following table”:
