6 Password Strength Checker

Description 📄

This project is a Password Strength Checker implemented in Python. It securely checks the strength of a user-provided password against predefined criteria and provides suggestions for improvement if the password is weak.

---

Features 🚀

1. Secure Input: Uses getpass to hide the password while typing.
2. Strength Validation: Checks for:
   • Minimum password length (8 characters)
   • Presence of lowercase and uppercase letters
   • Presence of at least one number
   • Presence of at least one special character (!@#$%^&*())
3. Interactive Feedback: Provides clear, actionable suggestions to improve the password.
4. Loop Until Strong: The program continues prompting until a strong password is entered.

---

Technologies Used 🛠️

• Python 3
• getpass: For secure password input
• re (Regex): For pattern matching and validating password criteria

---

How to Run 💻

1. Clone the Repository:

   git clone https://github.com/yourusername/password-strength-checker.git
   cd password-strength-checker

2. Run the Script:
   Run the Python file in your terminal or any Python IDE:

   python password_strength_checker.py

3. Input Password:
   Enter your password when prompted. The program will validate it and guide you to strengthen it if necessary.

---

Example Run 📋

Enter your password: ********
Weak password. Improve it by fixing the following:
- Add at least one uppercase letter (A-Z).
- Add at least one special character (!, @, #, $, %, ^, &, *, (, )).

Enter your password: StrongPass123!
Password is strong! No one can hack your account.

---

Password Strength Criteria ✅

A strong password must satisfy the following conditions:

1. Minimum Length: At least 8 characters.
2. Lowercase Letters: Contains at least one lowercase letter (a-z).
3. Uppercase Letters: Contains at least one uppercase letter (A-Z).
4. Numbers: Contains at least one digit (0-9).
5. Special Characters: Contains at least one symbol (!@#$%^&*()).
