The Password Checker Script is a Python tool designed to check the security of passwords by consulting the Pwned Passwords API. This script allows users to evaluate if a password has been compromised in previous data breaches.

The script is divided into several modules to enhance code organization and maintainability:

• api_utils.py: Contains functions related to making requests to the Pwned Passwords API.
• hash_utils.py: Includes functions for hash-related operations, such as generating SHA-1 hashes.
• password_checker.py: Implements the main logic for checking passwords against the Pwned Passwords API.
• main.py: The main script that interacts with user input and executes the password checks.

This module provides utilities for interacting with the Pwned Passwords API.

• request_api_data(query)
  • Requests data from the Pwned Passwords API for a given hash prefix.
  • Args:
    • query (str): The first 5 characters of the SHA-1 hash of a password.
  • Returns:
    • requests.Response: The response object from the API.
  • Raises:
    • RuntimeError: If the API request fails (status code other than 200).

This module handles operations related to password hashing.

• get_password_leaks_count(hashes, hash_to_check)
  • Parses the response from the Pwned Passwords API and returns the count of compromised passwords.
  • Args:
    • hashes (requests.Response): The response object from the API.
    • hash_to_check (str): The remaining part of the SHA-1 hash to check.
  • Returns:
    • int: The count of compromised passwords for the given hash.
• sha1_hash(password)
  • Generates the SHA-1 hash for a given password.
  • Args:
    • password (str): The password to hash.
  • Returns:
    • str: The SHA-1 hash of the password.

This module contains the core logic for checking passwords against the Pwned Passwords API.

• pwned_api_check(password)
  • Checks if a password has been compromised using the Pwned Passwords API.
  • Args:
    • password (str): The password to check.
  • Returns:
    • int: The count of compromised passwords for the given password.

The main script orchestrates the password checking process.

• main(file)
  • Checks a list of passwords for compromise using the Pwned Passwords API.
  • Args:
    • file (str): The path to the file containing a list of passwords.
  • Returns:
    • str: A message indicating the completion of the password checks.

1. Clone Script Repo:

   • git clone https://github.com/Mubarak1A/passwordChecker.git

2. Environment Setup:

   • Make sure you have Python 3 installed on your system.

3. Install Dependencies:

   • Install required dependencies using the following command:

     pip install requests

4. Sample File Content:

   • Customize the sample passwords by modifying the ```sample.txt`` file. The script reads the content from thi file and execute the main function base on the passwords in the file.

5. Run the Script:

   • Execute the script using the following command:

     python3 main.py <path_to_password_file>

     Replace <path_to_password_file> with the path to the file containing a list of passwords.

• Ensure that the Pwned Passwords API server allows requests from your environment.
• Use secure methods for handling and storing sensitive information, such as credentials.

Feel free to customize the script or modules based on your specific use case and security requirements.
