Password Strength Checker

Abstract

1. Introduction

A comprehensive password strength checking tool with both GUI and CLI interfaces. This application helps users create and validate secure passwords using advanced strength checking algorithms.

2. Objective

A comprehensive password strength checking tool with both graphical and command-line interfaces

This project demonstrates how Python can be applied to a real-world Cybersecurity & Ethical Hacking problem.

3. Key Features / Modules

• Dual Interface: Choose between a user-friendly GUI or efficient CLI
• Password Strength Analysis: Uses the zxcvbn algorithm for realistic password strength assessment
• Password Generation: Create strong, random passwords of customisable length
• Comprehensive Checks:
• Minimum length requirements
• Character complexity (uppercase, lowercase, numbers, special characters)
• Common password detection
• Banned password detection
• Improvement Suggestions: Get specific recommendations to strengthen weak passwords
• Export Functionality: Save password check results to JSON (GUI mode)

4. Technology Stack

• Python 3.x
• tkinter (included in standard Python distribution)

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Python 3.8 or later
• pip / virtualenv for dependencies
• VS Code, PyCharm or Jupyter Notebook
• Git (to clone the repository)

6. Installation & Setup

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

1. Clone the repository:
2. Install dependencies:
3. Ensure you have the required wordlist files:
4. weak_passwords.txt: List of commonly used weak passwords
5. banned_passwords.txt: List of banned passwords

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

pip install zxcvbn

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add logging and alert notifications (email / Telegram)
• Write a threat model document for the tool
• Package it with Docker for safe lab testing

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.
