- For
- QR-system implementers and readers checking signed QR content
- Worth noticing
- The signed message joins context, header, and content in that order; the example uses Ed25519.
Field notes
The demo breaks the check into signed message, signature, and public key, and shows the exact bytes intended for verification. Its example uses an Ed25519 signature and a domain-published key described as part of a QRSig v1 JSON document. The extracted page still shows some values as “Loading…” and labels verification “Not checked,” so it does not establish that the example completes a successful check.
