How to add UBLDocumentSignatures in UBL Extension? #39

Closed kurbhatt closed 3 years ago

kurbhatt commented 3 years ago

I have created 1 UBL document InvoiceType. It has all the required details. Now I want to add a Signature to the UBL document. The Extension will be used for this AFAIK. I have tried to find out this but I am not able to find the solution.

I tried with xades4j but there's 1 issue, it creates a Signature directly in Document(using ds:Signature), not in the Extension. I passed the UBL XML string to xades4j. I want it to be in structure:

`

urn:oasis:names:specification:ubl:dsig:enveloped:xades urn:oasis:names:specification:ubl:signature:1 urn:oasis:names:specification:ubl:signature:Invoice ` Please suggest me way to add a signature in the UBL extension.

I recommend to use the DSS library to add electronic signatures. See https://github.com/esig/dss/ for details.
