🔐 Password Strength Analyzer

A defensi tool that e password strength using rule-based analysis and entropy estimation, pro transparent feedback on why a password is weak or strong.

This project is designed to demonstrate secure coding practices, input , and security-aware software design.

🔐 Password Strength Analyzer

✨ Features

🧠 How It Works

Password strength is e using two complementary approaches:

1️⃣ Rule-Based Analysis

Checks for:

Password length

Character (upper, lower, digits, symbols)

Repeated characters

Sequential patterns (e.g. abc, 123)

Each rule adjusts a score and produces an explanation if weaknesses are found.

2️⃣ Entropy Estimation

Entropy is calculated using:

entropy = length × log2(character_pool_size)

This estimates resistance to brute-force attacks and prioritizes length o, aligning with modern security guidance.

▶️ Usage
python cli.py --password "Tr0ub4dor&3"

Example output:

Strength: Moderate (63/100)
Entropy: 57.21 bits

Issues:

JSON output:

python cli.py --password "Xy9!fQ2$LmR@p" --json

🧪 Running Tests
python -m pytest

🔒 Security & Ethics

Passwords are processed in memory only

No passwords are logged, stored, or transmitted

This tool is intended for defensive and educational use

Inspired by real-world authentication systems

📌 Future Enhancements

Crack-time estimation

Configurable password policies

Unicode character support

Packaging as a pip-installable tool
