InfoTc 1040 Introduction to Problem Solving and Programming Password Checker - Python 3.5

To keep a user account safe, its important to have a strong password. In this assignment, youll write a program that checks a users password and indicates how strong it is.

Requirements:

Well evaluate password strength based on the following criteria:

A password should contain

1. upper-case letters

2. lower-case letters

3. numbers

4. symbols (any keyboard character that is not a letter or number)

5. and it should not contain personal information or common words If a password meets

all 5 criteria, it should be rated as very strong

4 criteria, strong

3 criteria, moderate

2 criteria, weak

any less, very weak Passwords that are less than 8 characters long should not be accepted.

To check whether or not a password meets criteria #5, we should start the program by asking the user for their first and last names. Their password should not contain either name. The reason for that is that hackers often try to guess passwords by using personal information. A password that contains personal info is easier to guess. Likewise, there are many common words and phrases that people like to use in their passwords. Well say that a password fails criteria #5 if it contains any of these strings:

password 12345 qwerty letmein dragon baseball football starwars

The program should ask for and test a users password. It should then display the strength of the password and ask the user if theyd like to test another password. The next section contains sample output.
