🔐 Password Strength Checker - Modern GUI Implementation

This PR implements a comprehensive password strength checker with both CLI and GUI interfaces, addressing the request to improve the existing password checker with a modern, user-friendly GUI using customtkinter.

✨ New Features Added

🖥️ Modern GUI Application (password_checker_gui.py)

  • Beautiful Interface: Clean, modern design using CustomTkinter framework
  • Real-time Feedback: Password strength updates instantly as you type with visual progress bar
  • Password Visibility Toggle: Show/hide password with eye icon (👁/👁‍🗨)
  • Visual Strength Meter: Color-coded progress bar and strength indicators (red to green)
  • Smart Suggestions: Dedicated scrollable section with actionable improvement recommendations
  • Password Generator: Configurable length (8-32 characters) with special character toggle
  • Clipboard Integration: One-click copy functionality with visual feedback (📋 → ✓)
  • Theme Toggle: Light/Dark mode switching (🌙/☀️ button)
  • Responsive Design: Adaptive layout that works on different screen sizes

💻 Enhanced CLI Interface (password_checker.py)

  • Core Logic: Robust PasswordStrengthChecker class with comprehensive analysis
  • Interactive Menu: User-friendly CLI with options for checking and generating passwords
  • Detailed Analysis: Score (0-100), strength level, feedback, and improvement suggestions
  • Secure Generation: Cryptographically secure password generation using secrets module

🎯 Password Analysis Features

The checker evaluates passwords based on multiple criteria:

  • Length: Minimum 8 characters recommended, 12+ for strong passwords
  • Character Types: Uppercase, lowercase, numbers, special characters
  • Common Passwords: Checks against database of known weak passwords
  • Pattern Detection: Identifies sequential or repetitive patterns
  • Entropy Calculation: Overall randomness and unpredictability scoring

Strength Levels

  • 🔴 Very Weak (0-19): Critical security risk
  • 🟠 Weak (20-39): Easily guessable
  • 🟡 Medium (40-59): Basic protection
  • 🟢 Strong (60-79): Good security
  • 🔵 Very Strong (80-100): Excellent security

📁 Files Added

  1. password_checker.py (280 lines) - Core CLI functionality with reusable PasswordStrengthChecker class
  2. password_checker_gui.py (459 lines) - Modern GUI using customtkinter
  3. requirements.txt - Python dependencies (customtkinter, pyperclip)
  4. password_checker_README.md - Comprehensive documentation with usage examples
  5. password_checker_gui_demo.png - Screenshot demonstrating the GUI interface
  6. .gitignore - Proper Python gitignore to exclude build artifacts

🚀 Usage Examples

CLI Usage

python3 password_checker.py

GUI Usage

pip install -r requirements.txt
python3 password_checker_gui.py

Programmatic Usage

from password_checker import PasswordStrengthChecker

checker = PasswordStrengthChecker()
result = checker.check_strength("MySecureP@ssw0rd2024!")
print(f"Strength: {result['strength']} (Score: {result['score']}/100)")

🛡️ Security Features

  • No Password Storage: Passwords are never stored or logged
  • Secure Generation: Uses secrets module for cryptographically secure randomness
  • Memory Safety: Passwords cleared from memory after analysis
  • Offline Operation: No network requests required for core functionality

🎨 Technical Implementation

  • Modular Design: Clean separation between GUI and core logic for reusability
  • Real-time Updates: 300ms debounced input handling for smooth user experience
  • Error Handling: Graceful fallback to CLI if GUI fails to start
  • Cross-platform: Works on Windows, macOS, and Linux with proper tkinter support

📸 Visual Demo

Password Checker GUI

The GUI demonstrates:

  • Live password strength analysis
  • Visual progress indicators
  • Generated strong password with 100/100 score
  • Clean, accessible interface design

This implementation provides a production-ready password checking tool that exceeds the original requirements with excellent user experience and comprehensive security analysis.
