Password Strength Checker v1.0.1

Description

This Python program allows users to verify the strength of their passwords. Based on specific criteria such as length, the presence of uppercase letters, and special characters, the program assigns a strength rating to the password (“weak,” “average,” “strong,” or “very strong”). It also provides feedback on how users can improve their password strength.

Features

• Password Strength Classification:
  • Weak: Less than 6 characters.
  • Average: At least 6 but fewer than 8 characters, mixed letters and numbers, no symbols.
  • Strong: At least 8 characters, contains one uppercase letter, one number, and one special character.
  • Very Strong: At least 12 characters, contains one uppercase letter, one number, and one special character.
• Dynamic Feedback: Offers suggestions to improve password strength based on criteria.
• Loop for Reuse: Users can check multiple passwords in a single session.
• Secure Input Handling: Uses the pyinputplus library for password entry validation.
• Exit Option: Close the program by typing 'q'.

Changelog v1.0.1

Several flow improvements made to make code more readable and helps the code appear more organized.

• Created a second program Main.py to house the main control flow of the program.
• Kept all of the functions on Pass_Func.py for separation from the main program.
• Created main() which calls for user input and the the linked functions for checking the password.

---

Future Improvements

• Update password strength to a score based system to eliminate "hard coding" password requirements.
