Generate memorable, high-entropy passphrases using EFF wordlists.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Select 4 to 8 words (70+ bits entropy recommended).
Choose hyphen, underscore, or space.
Copy generated secure passphrase with zero network egress.
Multi-word passphrases offer high entropy against brute-force attacks while remaining easy for humans to remember and type.
Yes, 100% of randomness is sourced from window.crypto.getRandomValues() in your browser.
Zero-egress companion tools in the Security & Network suite
Measure cryptographic randomness, Shannon entropy (0-8 bits/byte), Chi-square test, and byte distributions.
Brute-force all 256 single-byte XOR keys with automated English frequency & chi-squared scoring.
Audit CSP, HSTS, X-Frame-Options, and security headers with OWASP grading (A+ to F).
Compare memory hardness, GPU ASIC resistance, and security parameters across KDF standards.
