Uppercase (A-Z) Lowercase (a-z) Digits (0-9) Symbols (!@#$)

🔬 Password Entropy & Strength Analyzer

Enter a password to see its strength.

Entropy: 0 bits

Time to Crack (Online): ~0 seconds

Time to Crack (Offline): ~0 seconds

Assumptions: Online attacks at 100 guesses/min; Offline at 10 billion/sec.

🧮 Visual Bcrypt Hash Generator & Verifier

Important: This is an educational demo. Real-world hashing MUST be performed on the server-side to be secure.

❓ Understanding The Toolkit

Is This Password Tool Safe & Private?

Yes, 100%. This is a **client-side** application, meaning all calculations happen in your browser. No passwords, hashes, or any data is ever sent to our server. Your privacy is absolute.

What is "Password Entropy"?

Entropy is a measure of a password's randomness, measured in **bits**. A higher bit count means more combinations, making it exponentially harder for an attacker to guess.

What is "Time to Crack"?

This estimates how long it would take to guess your password. We show two scenarios: **Online Attacks** (slow, like guessing on a website) and **Offline Attacks** (super-fast, on a stolen database).

Why is a Client-Side Bcrypt Demo useful?

While real hashing should ALWAYS be server-side, this demo is an invaluable **educational tool**. It visually shows how Bcrypt's "cost factor" makes it slow and strong against attacks.
