Password Security & Audit Tools
Understanding the mathematical strength of your credentials is essential for defending against credential stuffing, rainbow table lookups, and GPU cluster brute force.
Password Strength Checker
Evaluate any password in real time. Analyzes character distributions, calculates Shannon entropy, and simulates resistance against GPU attacks.
Password Entropy Calculator
Interactive mathematical calculator demonstrating how character pools and length combine to produce information entropy bits.
Password Crack Time Calculator
Simulate exhaustive brute-force attack durations across various hardware speeds, from web login throttling to nation-state supercomputers.
Password Length Checker
Audit passwords against 8, 12, 16, 20, and 24-character security thresholds in real time.
Password Complexity Checker
Check character set diversity, uppercase/lowercase distribution, digits, and special symbols.
