Entropy source

Picking a source changes the story on the receipt, never the quality: anything below class A is mixed with the OS CSPRNG before it reaches you. This result actually came from NOAA Space Weather.

There is no same-seed re-render here. Recomputing a secret from a kept seed is exactly the thing this generator refuses to make possible, so every change of parameters draws fresh entropy.

seed token withheld

Nothing to keep: no token is issued for a generator that makes secrets.

Class C · Observational cached

Planetary K-index 2.33 — the field was unsettled when this was made.

Carries only tens of bits of genuine surprise. Always mixed with the OS CSPRNG.

This generator makes secrets, so it is never given a shareable link. A password with a replayable URL is not a password — anyone holding the link could recompute it byte for byte, forever. The seed token is discarded the moment the response is written; nothing here is stored, logged or recoverable.

seed · withheld by design · numbers.password is marked sensitive

This page and /api/v1/g/numbers.password run the same code. There is no private endpoint.
