| Convert Evidence to VC | The DP prepares the diploma evidence according to the pre-defined XML schema. The service then converts the received canonical evidence in the XML format and converts the data into the JSON-LD format of the Verifiable Credential. | VC |
| Digitally sign the VC | The diploma evidence in the JSON-LD format is submitted to the HL Aries agent deployed on the DP side to attach the proof field, i.e. to append the digital signature to the VC by using the EBSI-compliant DID. An important prerequisite for this step is that the EBSI-compliant DID is registered in the EBSI DID Registry, and that the underlying DID document is imported to the HL Aries agent upon Authority Agent startup. | VC |
