🔒 Secure Password Checker

This is a Python-based password security tool that checks whether a given password has been exposed in past data breaches using the Have I Been Pwned API.

🚀 Features

✔ Uses SHA-1 hashing to keep passwords secure
✔ Leverages Have I Been Pwned API without exposing full passwords
✔ Provides real-time results on password security
✔ Helps users avoid using compromised passwords

📌 How It Works

1. The password is hashed using SHA-1 encryption.
2. The first 5 characters of the hash are sent to the API.
3. The API returns a list of potential password hashes.
4. The script checks if the full hash exists in the database.
5. If found, it informs the user how many times the password has been leaked.

⚠️ Security Note

This tool never sends your full password to an external server, ensuring privacy and security.
