Fileopen DRM for PDF circumvented

[orange99]

Found and fixed the issue. Had to check for 'update', in addition to 'Update' and others, in the urlresult in two places. Thanks for your work!

Tetrachroma thanks for banging out this script, you didn't want to have any fun anyway! Orange99 thanks for the timely debug.

Skillsoft decide to wrap their study guides in FileOpen DRM. Bad thing if you use an OS that Adobe, and therefore FileOpen, doesn't support! Here is the response I received on the issue. With your code working I have no need to wait on them any more.

I can only apologize for this. There’s a code signing issue with R9 and haven’t been able to determine whether the issue is in our code or Adobe’s. We had hoped to get it sorted out in the Reader X beta process. But Adobe decided not to create Reader X for Linux, so now we’re back to trying to make the plug-in work in 9. I have two engineers on the problem, hopefully it won’t fester much longer.

Best,

Sanford

I've just switched from a Sony eReader to a Kindle. I had a load of .epub files, which I converted (thanks!!). I've got one file which actually has a .pdf file extension. The method I used (Python scripts) doesn't work. Is there another way? TIA!

Never mind, I found it, I needed the ineptpdf.pyw script from here,

Huge thanks to everyone that's helped to make these methods work :-D

hi guys,

I'm using ineptpdf 8.4.51 on a pdf with Fileopen protection and keep getting the Error: "Cannot find decryption key". I keep the PDF opened in Reader 9.4 when trying.

Any suggestions?

Getting the same Error: "Error" message. What did you "update" to resolve this?

Hi,

first of all the script works perfect.

But i have on question:

Do anybody notice it, when i remove the protection (PDF-File protected with File Open).

I ask, because the removing only works with internetconnection.

Thanks and kind regards.

Hi, I've been trying to use indeptpdf 8.4.51 to decrypt a FileOpen protected pdf but am getting the following error in the debug log:

2nd preresultRetVal=0&Reason=BadUserPwd

The user/pw used are 100% correct and I can open the pdf with acrobat reader. Any hints of what the issue could be/how to resolve this?

I suggest you ask wherever you found the ineptpdf script.
