KronoSeal, an API for reproducible certified primes
KronoSeal turns an index into the same certified prime on any platform, with generation, validation, and audit evidence exposed through an API.
Field notes
KronoSeal’s workflow separates prime generation from local cryptographic libraries: a client submits an index, then receives a prime string, validation result, request ID, and server timestamp. The page says the same index produces the same result across environments and supports clients from browsers to smart cards. It documents a ceiling of 1,000 digits, while warning that the public demo is unreliable at that size and that inputs above 600 digits need a dedicated plan.
