Audit Password Strength & Shannon Entropy

Analyze password security with exact Shannon entropy bits, GPU cluster crack time estimates, and character diversity audits.

About This Tool

Password Strength & Entropy Analyzer evaluates passwords using mathematical Shannon entropy formulas, auditing character pool diversity (uppercase, lowercase, numbers, symbols) and estimating brute-force resistance against 100-Billion-hash/sec GPU clusters.

Key Features

Shannon entropy calculation in bits
GPU cluster crack time estimation
5-level visual strength indicator
Character diversity audit checklist

How to Use

  1. 1Type a password in the input field.
  2. 2Toggle password visibility using 'Show Password' if needed.
  3. 3Review the entropy score, strength meter, estimated crack time, and diversity checklist.

Why Use ToolSnippet Password Strength & Entropy Analyzer?

Evaluates real mathematical entropy rather than arbitrary complexity rules.
100% private and offline: passwords are never sent across any network.

Tips for Best Results

  • Aim for at least 60 bits of entropy and 14+ characters for sensitive master passwords

Frequently Asked Questions

What is Shannon entropy in passwords?

Shannon entropy measures the information density and randomness of a password in bits. Passwords with 60+ bits of entropy are considered strong.
