Hi Guys,
Hope you are doing great. After doing some digging and not getting the
desired results i thought that why not contact the developers of the
PDFBOX. I have a situation where there is a PDF which is password
protected. I know the user and owner password and i need to digitally
sign it. I successfully got the hang of signing part for unrestricted
file. Now when i try to add signature to a secure file i get the
following exception:

I hope that you guys can point me in the right direction. I am using
PDFBOX 2.0.0 and i used the code given in the example.
Looking forward to your response.
Sorry, known problem, it isn't supported yet, see also
