# Password Strength Checker
2+
3+
This is a simple Python script that evaluates the strength of a password based on complexity and security. It checks for various criteria like length, presence of uppercase letters, lowercase letters, digits, and special characters.
4+
5+
## How to Use
6+
7+
1. Run the `password_strength_checker.py` script in your Python environment.
8+
2. You will be prompted to enter a password for evaluation.
9+
3. The script will check the password against the following criteria:
10+
- At least 8 characters in length.
11+
- Contains at least one uppercase letter.
12+
- Contains at least one lowercase letter.
13+
- Contains at least one digit.
14+
- Contains at least one special character (e.g., '@', '_', '!', '#', '$', '%', '^', '&', '*', '(', ')', '<', '>', '?', '/', '|', '}', '{', '~', ':').
15+
4. Based on the criteria, the script will provide feedback on whether the password is strong or weak.
16+
17+
## Criteria for a Strong Password
18+
19+
To be considered a strong password, the password must meet all of the following conditions:
20+
1. Be at least 8 characters in length.
21+
2. Contain at least one uppercase letter.
22+
3. Contain at least one lowercase letter.
23+
4. Contain at least one digit.
24+
5. Contain at least one special character.
25+
26+
## How to Run
27+
