@cnewsgrp
what software are you using? are you trying to remove DRM from ePub or PDB ebooks?

Ok, but do you have ePub or PDB ebooks from B&N? This method works with EPUB files only.

If you get the "B&N User Key not found. Unexpected DB format?" error, you can try to remove the "ClientAPI_v012.db" file, then re-authorize BNReader with your account information. Alternatively you can use the key-derivation script (ignoblekeygen). Both ignoblekey and ignoblekeygen will produce the same output when they work correctly.

Also make sure you use the name from the Credit Card, not your B&N username.

If you need to remove DRM from PDB files, read the following thread:

The books are ePub books. I have tried this several times now and still not working. From your comment (Also make sure you use the name from the Credit Card, not your B&N username.) it seems that I am doing something wrong.

How am I supposed to run this? I have done following things
1) Downloaded BN eReader for PC, logged in and downloaded my ebooks. I see them under "C:\Users\MyName\Documents\My Barnes & Noble eBooks\MyEmailAddress"
2) Downloaded and installed Python 2.6.
3) Downloaded "ignoblekey.py"
4) I double click and see the error "B&N User Key not found. Unexpected DB format"

What am I doing wrong?

I have Windows 7 PC. Also want to add that I have tried deleting ClientAPI.db file multiple times and that the file is always called ClientAPI.db - not ClientAPI_vXXX.db. File location is C:\Users\MyName\AppData\Roaming\Barnes & Noble\BNDesktopReader

I am all set. I can still not get ignoblekey.py to work, but ignoblekeygen.pyw works.

For the confused people like me. Here are instructions in plain english.
1) Go to http://i-u2665-cabbages.blogspot.com...-for-epub.html
2) Download ignoblekeygen.pyw and ignobleepub.pyw
3) Download and install Python 2.6 and pycrypto-2.1.0 in that order
4) Login into bn.com and write down your user name (not the email address) and credit card # on file.
4) Double click ignoblekeygen.pyw. Enter your user name (not the email address) and credit card # on file. It should generate bnepubkey.b64 file if all is well.

5) Double click ignobleepub.pyw. Enter input file (epub file with DRM downloaded from BN). Output file (any file name)

Ok, i am COMPLETELY lost. I've downloaded the python 2.6, and went to bout the websites (ignoblekeygen and ignobleepub), but they both tell you to go to the same voidspace page (http://www.voidspace.org.uk/python/m...shtml#pycrypto)
and download the same thing (PyCrypto 2.1 for python 2.6)and name it 2 different names.

I installed python 2.6 and the pycrypto file, ran both and was never asked to enter the name and cc# for my key. I really have no idea what I'm doing (hence the username lol), and would appreciate any help on figuring this out.

Thank You
