How to Crack Secured PDF Files and eBooks in Four Easy Steps

Are you using a textbook PDF for one of your classes that has a million limitations? I know I did and quite frankly I could not stand the fact that I was unable to read the textbooks I paid for on my iPad. After a little digging and some trial and error I found a method to decrypt secured PDF files, sealed PDF’s, and encrypted PDF’s so that you can enjoy them on any device without restrictions. I will use the guide below to explain to you how this works and show you how to hack your secured PDF’s. If you have any comments or questions please use the comments form at the end of the article.

Note: The PDF files you wish to extract must have printing enabled for this to work. Also because we pass the print spool to a PDF the document will lose the ability to search etc. I am in no way shape or form encouraging anyone to use these copied PDF’s to violate copyright law. All I am showing you is how you can remove these ridiculous restrictions from an eBook you paid for so that you can use it on other devices like the iPad.

How This Works

Spool files exist to hold information that is on its way to a location on your computer, in this case your printer. Because a printer can only print one item at a time the computer creates a spool file that contains the information form the file you are printing. This spool file is slowly fed to the printer as it is printing. When you print an SPDF (secured PDF file) the spool file is unencrypted unlike the SPDF file so what we do is grab that spool file and print it to a PDF printer like Foxit so that we can convert the Spool file to a PDF file we can use. The resulting PDF file doesn’t have any of the restrictions associated with the original file.

Here’s a diagram to break it down for you.

We are able to extract the spool file because we print to a non-existent virtual printer. This allows us to extract the unencrypted PDF spool using SPLView. In this guide rather than create a fake printer we will simply empty the paper tray which forces Windows to store the spool file until the printer begins printing.

Step 1: Download and Install Applications

Before you proceed you will need several applications in order for this to work. All applications have been tested and can be removed after you hacked the PDF files.

Foxit (download) This application is used to print the spool file to an unrestricted PDF.

SPLView (download): This is used to open the spool files so that we can print it to the PDF printer.

Please download and install these applications before proceeding.

Step 2: Open the Secured PDF File and Print

1. Open the protected PDF and click on the Print button in the Acrobat window, not the browser.

Note: SPDF’s requiring authentication with the server will open within the browser window using the Acrobat viewer. If you use the browser’s print button you will not be able to extract the SPDF, you must use the print button from Acrobat.

IMPORTANT – Remember to remove all paper from the printer’s paper tray. This is necessary so that you can access the temporary spool file for the following steps.

2. Select the fake printer we created and click OK to print the SPDF. This will create the spool files necessary to extract the SPDF in the next set of steps.

Make sure that the print job was completely sent before proceeding to the next step.

Step 3: Open SPLView to Print the Spool File

Open the SPLView application.

Note: Spool files (.spl) are located in C:>Windows>System32>spool>PRINTERS.

7. When the print job opens you will notice that it is the SPDF file you printed. Verify that the file is intact (images, text, and formatting match the original SPDF).

When you are ready click on File to open the menu.

8. Click Print from the menu.

    I placed this comment below, but I believe it is a pressing enough issue that i should make a separate post about it. When I was trying to access the spool file, I received an error message complaining about insufficient privileges.

    To solve this error, I needed to open the folder where it saved the printer spool files (c:windowssystem32spoolPRINTERS) and manually make a copy of the spool file, as my printer was continually trying to access it, preventing SPLView from working its magic. I hope this helps!

      Thanks for the feedback, I will incorporate it as a note in the guide.

    hey it didnt work for me. When i clicked “open the job” on SPLView, it says “insufficient rights to read the file”…what is the reason behind?

  • Mdjbhouse

    I seem to be missing something where in step 2 it says to print to the fake printer we setup??
    splview is also giving me some grief about security to the spool folder (Vista) I’ve navigate to that folder and I should have permissions now but still can’t to open my spool file (which is with me printing to my real printer just with no paper in it).

      You should do this as an administrator. Regarding the printer, you will need
      to install a virtual printer as instructed in the guide.

    Hi, Can you tell me, exactly which version of Foxit I need to download. Thanks

    • http://www.gilsmethod.com Gilberto J Perera

      Zafar,

      I downloaded the latest version of Foxit at the time when I wrote the
      article, so the latest version should suffice.

    Thanks but It wouldn’t work on my windows 7 computer. The SPL viewer says “there are insufficient rights to print from file or folder.” Stupid DRM

    • http://www.gilsmethod.com Gilberto J Perera

      If the file has Print disabled, this method will not work…

    • boodrm

      My file is printable and I still get this error message.

    • http://www.gilsmethod.com Gilberto J Perera

      Could be a different DRM that is used that is not allowing this method to work. Not sure what else you can try here. If I find anything I will post it here.

  • Cbradley

    i keep getting the spooler file could not be opened… Insuf rights from read folder etc with the spl viewer.
    Back to the Foxit…i think if you download the OCR file it becomes searchable.

    anyone got any other ideas?

    • Vince

      There’s other print-to-pdf programs available that might bypass it. I usually use PrimoPDF, but it kept kicking back on error with this one particular file, which is how I ended up here.

    • http://www.gilsmethod.com Gilberto J Perera

      Did it work for you though?

  • http://tdmachinetools.com LUKI

    Printed the spdf with foxit pdf creater. Didnt need to do anything else. Shame its not searchable though.

    • http://www.gilsmethod.com Gilberto J Perera

      Glad it worked for you. Yes it is a shame that it is not searchable.

      You have to run OCR text recognition on the final pdf to make it searchable. In Adobe, it’s under the “Edit” tab. In FoxIt, it’s available under the “Tools” tab.

      Thanks for the tip.
