Hi Tilman,

Thank you so much for your reply. my test code was from PDFBox 2.0.0; 
which I replaced with PDFBox 2.0.1; now I am not getting "Invalid 
Signature" message anymore. I do see the stamp "Original" in my signed 
PDF, the signature is on that stamp.jpg; I wanted to see the actual 
digital signature, trying to figure out how to remove the stamp and 
display the actual "Digital Signature". I am kind of new to Netbeans and 
java as such.

There must be some problem, because this is the top of 

class CMSProcessableInputStream implements CMSTypedData

that file is in

Did you include that file in your project?

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!
