Verify a deletion certificate

Check a deletion certificate or a signed export receipt from Harmonyx Solution Co., Ltd. (OurGrowth Kairos). The file stays in your browser and is never uploaded. The page fetches only the published key list.

The page checks that the key list is signed by the root key you entered, that the document's key is on that list and was valid and not revoked on the document's date, and that the signature matches. The same check from a terminal: node scripts/cell-teardown.ts verify <file> --key-list https://records.ourgrowth.ai/.well-known/deletion-keys.json --root-key-id <id>.
