How to get info of digital signature in a pdf document


I have a requirement to check the digital signature info (at least the total of digital signatures) in the specific pdf document.

So the user use Adobe to put their signatures and we need to check the signatures info (total, the identity if possible) with Aspose.pdf library.

Is this possible? Would be nice if you able to provide a sample as well.


Aspose.PDF API has support of adding and retrieving signatures in the PDF document. SignatureField class allows to retrieve the content, please refer to this help topic: Extract Signature Information
