Check a Wizzad record

Every Wizzad record is signed, and the key that checks the signature is published. This page checks it in your browser — nothing is sent anywhere, and none of Wizzad's code is involved. Read what a record is before you rely on one.

1 · The record

Paste the record's link and fetch its documents (from the link's own origin)

or paste the two documents by hand:

The signed record — the /api/proof/shared/<token> document The published keys — /api/proof/keys, or the issuer's did.json

2 · A file you hold

If the student brought a piece in as a file, or the record names a recording, the record carries the file's SHA-256. Hash your copy here (it stays on your machine) and see whether it is on the record.

Drop a file here, or choose one

3 · An Open Badges credential

A task's credential carries a Data Integrity proof (eddsa-rdfc-2022), which needs RDF canonicalisation to check. That is a larger library than belongs in one page, so check credentials with the command line: npx wizzad-record credential credential.json --keys did.json.
