DCQL query: QESAC

When to use

Use this skill when you ask a holder to authorise a qualified electronic signature. QESAC is the Qualified Electronic Signature Authorisation Credential. The holder keeps it in the wallet, and it points to a signing credential that a qualified trust service provider holds.

The query is small on purpose. It asks for one claim, credentialId, which names the signing credential to use. The document that the holder signs does not travel in the DCQL query. It travels in the transaction data of the verification request, as a hash.

Use this skill when you build:

• a "sign this contract" flow in a browser or an app;
• a signed PDF flow, where the server stamps the returned signature into the document.
