KeySigned What KeySigned is

Verify a vehicle condition record

Check that a sealed condition record has not been altered since it was signed. Everything happens in this browser. Nothing you add is uploaded, and checking makes no network requests, so it keeps working saved to a disk and opened offline.

Drop the evidence pack here

Either the -evidence.zip file, or the loose checksums.json, evidence.json and manifest-signature.json files from the evidence folder.

Not got a record to hand?

Both are built from sample files rather than a real vehicle, and this page will say so even when every check passes.

Optional: confirm the signing device

A record is sealed by one specific device. Paste the device fingerprint the business published (on their invoice, letterhead or website) and this page will confirm the record was sealed by that device rather than merely by some device. Leave it blank if you do not have one.
