Random value generator

This tool generates random values in your browser while reseeding the local CSPRNG with fresh entropy from physical SDR radio noise.

Where does the randomness come from?

Standard random number generators built into operating systems and programming languages (PRNG) rely on deterministic algorithms. They are fast and useful for simulations, but their sequences may be predicted if the initial state or seed is known.

Big Bang Entropy uses physical electromagnetic noise, including Johnson-Nyquist thermal noise, quantum noise in components, and cosmic emissions received by SDR stations. Samples are passed through SHA-512 conditioning to reduce statistical bias.

⚠ Cryptographic notice

For SSH, RSA, or cryptocurrency private keys, mix external entropy with the local system source (`/dev/urandom` or `crypto.getRandomValues()`). Do not rely solely on a single external API without local mixing.

Frequently asked questions (FAQ)

Are generated values stored on the server?

No. Values are generated in your local execution context after entropy seeds are fetched. The server does not store generated passwords or history.

How can I fetch raw entropy through the API?

Fetch raw bytes in binary format with `GET /raw?bytes=64` on the API server.
