Hello! I wanted to test digital signature using PDFBox. I downloaded pdfbox-app-2.0.1.jar 7.9MB on my local computer. In Netbeans 8.1, I created new project and from main class I am calling TestCreateSignature.testCreateVisibleSignature(). I generated new pfx key using Adobe reader DC and used that for my test. New (output) PDF is getting generated but when I open the PDF it says that the signature is invalid. How can I get this to work? At this time, I am using PDFBox just for testing to see if we can use it for real life. I am attaching my input and output pdfs. One more thing, I had to change following code from CreateSignatureBase.java, as was not getting compiled in Netbeans.
Original Code: Modified Code: Any help would be greatly appreciated! Thanks Naresh From: [email protected] To: [email protected] Date: 04/28/2016 08:54 AM Subject: WELCOME to [email protected] Hi!
