How to remove DRM from NookStudy PDF


 
I downloaded a book from barns and nobel. I have it on my nookstudy software. I found the pdf file but its drm protected. How can I remove it?

Is it a PDF file or a PDB file? Have you purchased this ebook or rented it?

I'm in the same boat. I've thought I was purchasing a book, and now it turns out that I've only rented it and I can't even put it on my mobile reader.

Can you open this PDF file with Adobe Digital Editions?

mrnagrom 09-20-2010 09:04 AM

Re: how to remove drm from nookstudy pdf


 
nope.

you open it in the nookstudy application and i've been poking around in the prefs dir and i only see an sqlite db called clientapi.db with a bunch of obvious information and an email address/password/device_id and some other information that's seemingly encrypted.

Heres a link to the files I have used to crack Nookstudy.

Keep in mind, this skitters the border of illegal as it gets around the rental agreements.

First thing, download the B&N reader program and Nookstudy.

Run the key retrieval .py and then run the other .py and use the key you got from the first script. Run it on your PDF and done.

So I highly recommend to delete the DRM free PDF file after your rental period is over.

DRM removal should only be used to read your PDF file on a Nook or some other eReader. Please do NOT abuse rental licenses!

you first have to open adobe digital editions and authorize with adobe.com, but your barnes and noble account id and your adobe id have to be the same.

then it works the same way as the regular digital editions drm removal from PDF.
Hopefully B&N will allow Nook Study books to be read on Nooks, since this seems to be exactly the reason why most of their customers try to remove DRM from NookStudy PDF files.

Re: How to remove DRM from NookStudy PDF


 
I am going through the same issue. I need to have the PDF for NookStudy to be able to get it on my Nook. I tried several things including doing the epub removal which didn't work really needless to say. I bought the nook because I was lead to believe that I could read it on it. One would assume. Also that link that takes you to the mediafire thing isn't working right now.

The link is working now. It will rip out any of the encryption for NookStudy PDFs.

I'd like to thank Deamos for their help. You really helped me out. I had a problem getting it to work at first, but it turns out that activating Adobe Digital Editions does make a difference in the outcome. I also had Nook and Nook Study running and logged in, although I don't know if that was necessary.

Can you explain this a little more clearly?

I downloaded the mediafire file.
I have Nookstudy
I found the drm protected pdf
I installed python 2.7
I installed pycrypt
Now what?

You need to download the mediafire link.
Have installed and be viewing either the rental or the "purchase" Find the pdf. For the sake of simplicity make a folder on your drive close to your root. Install python 2.7. Download and install PYCRYPTO. the O is important. http://sourceforge.net/projects/pycrypto/files/
Move the mediafire stuff in the folder with the pdf.

Now open the file within NOOK App. Run BNKeyretreival you can simply double click it if you have followed the above directions. Now you should see the "adeptkey.der" in the directory with your pdf and BNKeyretrieval. Now run "ineptpdf2" again you should be able to just click on it.

Now if you did it right the key will be autofilled, if not, fill it in. If you dont have the key you have skipped a step. Next select your file. Then select your output. For gods sakes do not make them the same. Wait a bit, be patient. You will have an un-DRM version of whatever. It is up to you to use this only on books you own. You have been warned.

Re: How to remove DRM from NookStudy PDF


 
Could somebody post step-by-step instructions on how to do this for non-computer savy people? I'm having a hard time figuring out what to do. I installed those two programs but they don't seem to exist anywhere other than add/remove programs. I couldn't get anything to run so I uninstalled and deleted everything as I was worried about what I had downloaded. Someone said something about being sure everything is in the same root but I don't know what that means? Should I copy and paste the pdf file from My Barnes & Noble Ebooks into another folder on my desktop then install everything else there? I have Adobe Digital Edition installed and authorized and can open my textbook in that program, but I don't see the pdf of the textbook in My Digital Editions, only in My Barnes & Noble. Some extremely detailed, step-by-step instructions would be GREATLY appreciated as I have a week to get a book I purchased through Nookstudy on my Nook Color! I don't want to be tied to my computer in order to read my book that I paid for, this is why I got a Nook Color! HELP!

Re: How to remove DRM from NookStudy PDF


 
Okay, disregard my previous post, I DID IT! Woo hoo! I now have a DRM-free pdf of my book! Sweet! (can you tell, I'm a little excited).

Now I have a new question. Am I going to have to do all these downloads every time or if I save these files, will they work on all my books? Thank you to whoever figured out how to do this! Of course, now that I have decrypted my book I bet NookStudy will get opened up to the Nook ereader devices. Oh, well! At least I have my book for the beginning of classes. Thank you!

Not sure I understood your question correctly. If you save DRM-free files, you should be able to open them on many devices.

p.s. I like that Nook Color has a color touch screen, but since it is an LCD screen, not an eInk screen, I prefer to use Kindle.

Re: How to remove DRM from NookStudy PDF


 
Am I going to have to download the mediafire files, Python, and Pycrypto every time I want to remove DRM from a downloaded NOOKstudy book?

Also, I am REALLY hoping for better PDF file management with the next update. I hope that they add highlighting, searching, and bookmarking! Anyway, I am glad I found this site, I've learned a lot.

You can leave them on your computer. Sometimes you may need to download the updates of the scripts; But if the old ones work for you, you don't have to do that.

Re: How to remove DRM from NookStudy PDF


 
Okay, I have been trying to follow the instructions posted here, but no luck.

I am using a computer with 64-bit Windows 7. I tried using both the Python 2.7 AND 2.6 versions and their Pyrocrypto counterparts, but I cannot get Pyrocrypto to install. I get the following error: "Requires Python 2.6, which was not found in the directory" or "Requires Python 2.7, which was not found in the directory". But I have installed both of these versions and allowed them to be placed in C:/Python26 and C:/Python27. Pyrocrypto will not allow me to type the directory in the box provided.

What am I doing wrong?

Thanks for your help.

Re: How to remove DRM from NookStudy PDF


 
Hello! I'm having a bit of a problem with this DRM-removal technique and I was wondering if anyone knew why. I followed all of the steps exactly, installed what I was supposed to, and the PDF that I bought from NookStudy converts into a DRM-free version... at least, half of it does. Every odd-numbered page is there and in great shape, but every even-numbered page is just a nice white sheet of nothing.

I tried using Python 2.6 and the version of PyCrypto that goes along with it, but still I'm missing half of my book. I went up and started working with the inept scripts that make use of Python 2.7 and its version of PyCrypto, but there is no difference. I've redownloaded the book from inside the NookStudy program, but that doesn't help either.

It's funny how I can't read my NookStudy books on my Nook Color. Does anyone know any solutions, or even what the problem is?

I'm having a similar problem. When I go to run the first script it says I still need to install pycrypto even though it appears to have installed correctly in the site-packages folder. I've also tried both versions, and I'm also using 64-bit Windows 7...

Try to use Python 2.6 32-bit and PyCrypto for Python 2.6.

Try to use a Calibre plug-in first. If it doesn't work for you, then try to read the readme files for standalone PDF (Adobe Digital Editions) DRM removal programs:
DRM Tools Archive for ebooks

The archive comes with readme files. Reading sticky may also help.

I can not figure it out! I am sooooo confused. I have been trying this for an hour or so. Is it possible for you to do it for me. The name of the ebook through nook is criminal procedure, 8th edition by Joel Samaha. Please please please. That would be awesome!!!

I remember that I used a program that can copy a PDF from the protect PDF, and the new one can be read and edit without any DRM.

What program was that? And what kind of protection was used in your PDF files?

I've just updated my Nook Study app and I am not able to decrypt anything. I suggest you don't download the new version of the B&N app. :(
