Drop in any supporting document. Your browser computes its SHA-256 fingerprint and compares it with every certificate in the registry on Base. The file never leaves your device, and no AICYBER server is involved.

  1. Choose a file; its fingerprint is computed on your device
  2. The registry contract is read directly from Base
  3. See the matching certificate and document number

The result appears here. The check reads the registry contract on Base directly; no AICYBER server is involved.
