Verify an anchoring receipt
Upload a receipt JSON and, if you have it, the manifest file it covers. The checks run against the certificates embedded in the receipt itself.
Receipt JSON (required)
Manifest file (optional)
What gets checked
The page rebuilds the receipt's signed core, verifies Lumethic's signature over it, verifies the independent RFC 3161 timestamp that covers that signature, and, when you supply the manifest file, recomputes its hash and re-derives the summary the receipt claims. The bytes are the truth. The receipt only summarizes them.
You do not need this page
The receipt embeds every certificate required for offline verification. An expert can run the same checks with standard tools such as openssl, without trusting Lumethic or this page. The hosted check is a convenience, never a requirement, and receipts are never revoked, so there is no status to look up.
