I have a pdf document (an electronic transcript from school) which, as the website from which the pdf file was downloaded says, "are certified PDFs that contain a digital signature and other security features", and "utilizes Adobe's secure certified PDF technology and therefore may only be viewed using the free Adobe Reader".
I can open it in Adobe Acrobat Pro on Windows. But I am using Ubuntu only.
I tried to open it in Evince in Ubuntu, but Evince says the file is locked and required a password. Is there a way to view it on Ubuntu?
I printed from Adobe Pro using some pdf printer, and the output pdf file can be viewed in Evince, but has "VOID" added as watermark as well as the text is rasterized (not searchable), which is undesirable.
