Zero-Knowledge Cryptography
Cryptographic Password Suite
Generate NIST SP 800-63B compliant passwords, EFF multi-word passphrases, and test existing credential strength offline. Computed 100% inside your browser's CSPRNG (window.crypto). Zero data leaves your device.
Password Strength: Ultra Strong
Shannon Entropy: 128 bits
Brute Force Resistance: Centuries
Pool: 94 chars

100% Client-Side CSPRNG
Every byte is produced with the Web Cryptography API (crypto.getRandomValues) directly within your device's memory. Zero network packets transmitted.
Real-Time Entropy Metrics
Calculates true Shannon information entropy \(H = L \cdot \log_2(N)\) and offline cracking resistance based on trillions of guesses per second.
Enterprise Compliance
Complies with NIST SP 800-63B, ISO 27001, and PCI-DSS requirements for password entropy, complexity, and unpredictable randomness.
