We have a requirement to merge the singed document to create a report. for that we need to extract few pages of the Signed doucment.
But we could see that the signed document is password protected for extraction.
What is the password of the signed document created after users successfully sign the document.
What kind of information you want to extract from signed document?
Does it some field values signer input during Signing Ceremony? If so, you can elicit these date from package metadata.
Or if you still want to unlock the document and extract from there, here’s a thread where has a solution by using iTextSharp.
In this case, you can use a flatten version PDF(which are akin to images) to merge into your report. There’s an API for you to download the flatten pdf document:
This is currently not a function in .Net SDK, so if you want to apply this solution, I can create some sample code using REST call for you.
Or you can use tools like iTextSharp to unlock the pdf at your side.
