Generate High-Entropy Passwords, Bearer Secrets & 256-Bit Keys Locally

Q: How is this different from Math.random() password generators?

Math.random() is not cryptographically secure. This tool uses window.crypto.getRandomValues(), which draws directly from your operating system entropy pool.

Powered by browser hardware CSPRNG (window.crypto.getRandomValues) with real-time Shannon & pool entropy bit calculation and offline crack-time estimation.

How to Use the Password & Key Gen

STEP 01

Choose your desired secret length (16 to 64 characters) and character pool.
STEP 02

Copy any of the 10 freshly generated cryptographic secrets or API tokens.
STEP 03

Verify the calculated entropy bits (128+ bits recommended for production signing keys).
