Custom Python Script to Check and Improve Password Strength

Project Title: Custom Python Script to Check and Improve Password Strength

Overview:

This Python script is designed to help users assess and enhance the strength of their passwords. By evaluating various aspects like length, complexity, and randomness, the script provides an easy-to-use tool for both checking the strength of existing passwords and offering suggestions for improvement.

Key Features:

Password Strength Checker: The script evaluates a password against common security metrics, such as length, use of upper and lower case letters, numbers, special characters, and checks against common password databases to assess vulnerability.

Suggestions for Improvement: Based on the evaluation, the script provides actionable suggestions on how to improve the password, such as adding more characters, mixing in different types of characters, or avoiding common phrases.

Password Generator: It can generate strong, random passwords that meet recommended security criteria, helping users create robust passwords effortlessly.

Customizable Rules: Users can adjust the script to enforce specific password rules, such as a minimum number of digits, special characters, or uppercase letters.

Security Recommendations: Offers tips on best practices for password creation, such as using a password manager and enabling two-factor authentication.

Technologies Used:

Python 3.x

re (Regular Expressions) for pattern matching

random for password generation

hashlib for cryptographic hashing (optional, for advanced features like checking password hashes)

Third-party libraries like zxcvbn or password-strength-meter for advanced password analysis (optional)

Use Cases:

Individual Users: Strengthen personal password security for online accounts.

Security Auditors: Evaluate and ensure password policies in organizations are robust.

Developers: Integrate the script into web applications or systems for real-time password validation.

Benefits:

Improved Security: Users can ensure that their passwords are hard to crack, reducing the likelihood of account breaches.

User-Friendly: Provides clear feedback on password quality and improvement suggestions.

Versatile: Can be used for personal, professional, or organizational purposes.
