Generate cryptographically secure API keys, auth tokens, and secret seeds.
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.
Enter an optional prefix like sk_live_ and select Base64URL, Hex, or Alphanumeric format.
Select 128-bit, 256-bit, or 512-bit cryptographic randomness.
Bulk generate up to 20 secret keys and copy them with one click.
Yes, keys are generated using the browser's cryptographic window.crypto.getRandomValues CSPRNG engine.
