How to remove DRM protection from B&N (Barnes & Noble) EPUB ebooks

[jen456]

When I run the ignobleepub script, I get the message 2940000719480.epub: not an B&N adept EPUB. Most of my B&N books have numbers not a title. Any ideas what I need to do?

Make sure such EPUBs are from B&N. Also make sure they are DRM protected (you can convert them to other formats using Calibre if they are not)

Like StreamRecorder says, I found that not all B&N books are DRM protected. I had also assumed they all were, and got the same error once.

There is an opensource ePub editor called Sigil [windows and mac]. I highly advise getting it, because you can use that to test if an epub has DRM or not, as it won't open DRM works. If there is no DRM it will open the file, and then you'll know.

NOOK App is just an updated version of BN eReader (BN Desktop Reader).

The NOOK app is used to read Barnes & Noble eBooks on your handheld device or computer. It allows to read Barnes & Noble eBooks. B&N eBooks are encrypted to protect the authors' work. Thus, other eBook Readers will not work with Barnes & Noble eBooks. The NOOK app can display styled text (italicized, underlined, etc.) and formatting as well as perform functions not found on other eBook readers. The NOOK app is FREE and is supported on multiple devices

If you have BN Reader v.2.5, then when you run ignoblekey v.2, you can get the following error:
"Could not locate B&N Reader installation".

Please someone help me. I just want to read my book. When i run the Decrypter It comes up with this " Error: error 3 while decompressing invalid code lengths set" Also i can't get the 'ignoblekey.pyw' to work. I keep getting the error 'error could not locate b&n reader installation.' I have the newest one so i think that's the problem there.
This sucks, i don't know what i'm doing.

This is confusing... trying to find up to date instructions across several threads and multiple posts.

First question:
Do I need pycrypto to use ignoblekey or is that just for ignoblekeygen.py?

Second question:
With nook desktop reader 2.5.1.xxx, will ignoblekey work at all?
It is not clear from the seemingly conflicting posts on the threads.

I was getting the "Error: Could not locate B&N Reader installation"
I made the following modification to ignoblekey.pyw
BN_APPDATA_DIR = r'Barnes & Noble\BNDesktopReader'

and got the "Error: Problem locating B&N Reader DB". I made the following modification:
dbpath = glob.glob(os.path.join(bndir, 'ClientAPI*.db'))

and got the "B&N User Key not found. Unexpected DB format?"

I deleted ClientAPI.db from by Application settings, but all the Nook reader asks for is my B&N
account email and password. Which does not seem to fix the error. Am I supposed to do something with my account setting on the B&N Website?

Update:
ignoblekeygen worked, so the question still stands has the current versions of the nook desktop reader broken ignoblekey even after updating the directory/file names?

All right, my fine folks, I've searched around and have been unable to find any solutions for this particular snag: when I run ignoblekeygen I get an error message that reads "Error: [Errno 13] Permission denied: 'bnepubkeyb64'". I saw one other post with someone reporting this error on the I<3 Cabbages blog, but there were no answers given, and the author hasn't commented on it in a GOOD long while.

Particulars: running Windows 7 x64, python 2.7.1 (32-bit, as per instructions), OpenSSL 1.0.0 (also 32-bit). Also installed pycrypto to see if that would make the difference, but no dice.

Any help is appreciated! Thanks, everybody!

I'd suggest trying the latest tools in the tools v3.0 archive (latest link always on my blog - see my profile), and if you still have problems, asking there, which where the maintainers of the scripts hang out.
