    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.

    Hi Anil,

    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.

    Hope this could help you!

    Hi Duo,

    We need to Create a pdf by merging multiple pdfs and one of them is the pdf signed by one span.
    We use dynamic pdf http://www.dynamicpdf.com/ for merging.

    We found that when a pdf is signed by one span it is password protected, which prevents the extraction of pages from the signed pdf.

    The dynamic pdf merger tool need the password to merge the signed documents.

    so do you know what would be the password used when a document is signed by one span.

    Please find the images of password info and restrictions on a sample pdf signed with one span solution.

    Anil,

    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:

    GET /api/packages/{packageId}/documents/{documentId}/pdf?flatten=true

    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.

    Hope this could help!

    Hi Duo, Thanks for the response. Just want to know if the flatten version of the pdf has digital signature?

    Hi Anil,

    The attachment is a sample flatten pdf that you can expect, where the sealed signatures are converted into plain texts and images.
