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.

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.
