🔐 Password Strength Checker

📌 Project Description

This is a simple command-line tool that evaluates the strength of a password based on five security rules:

✅ Minimum 8 characters

✅ At least one uppercase letter

✅ At least one lowercase letter

✅ At least one digit

✅ At least one special character (!@#$%^&*(),.?":{}|<>)

It uses regular expressions (re module) for pattern matching and secure password input (getpass module) to hide the password while typing.
