When validating signatures on a signed/filled pdf document using Document Security I cannot get no signature field name nor SignatureInfo attributes like signer, contactInfo, reason or date, although such information is present and visible inside pdf document. All I am getting from such fields is a lot of question marks (???????????????????????), i.e. sigInfo.date returns a string containing 67 question marks. Needles to say this same thing happens on different pdf forms, and signature fields.
I want to be able to get information about the signer of a certain signature field and which fields were not signed or invalid.
