Furious after book download to PC from Angus&Robertson here in Australia would not let me transfer to my Blackberry, I combed the web, not being a competent hacker or python programmer.
Your amazingly helpful instructions and downloads helped like a dream, and I was then able to convert to PDFs using Calibri.
I am very grateful to those selfless hackers like yourself who give of their time and expertise for the benefit of us knuckleheads.

Thank you.

Hi, I am having some problems. I use a Mac with OS X (Ver. 10.6.4) installed. I have already successfully downloaded Python and Pycrypto to my computer. However, when I wanted to run the scripts, (ineptkey and ineptepub), I couldn't. I tried double clicking them, even after changing the file extension to .pyw from the .txt file that they originally came in, but they would not run. Am I doing something wrongly? Please help!

Worked perfectly on a Windows 7 installation. It was so fast that I didn't believe it had done anything.

DMR is evil! When I pay good money for an eBook, I want the flexibility to view and archive the material as I see fit.  Now I can use the ePub books (that I legally have a right to view) with my favourite eBook reader and on all my mobile devices.

Thank You!!

Everything is okay until I run the Automated Inept epub script.  Points to the correct input path with two downloads with EXT ACSM and the output path.  Click <Decrypt> button, but nothing happened - no decrypted files in the output directory?  Don, can you clarify this?  Many thanks in advance for your time.

reply

How about renaming the .txt file to ineptkey.pyw? If you get a decryption key error you have to create the adeptkey.der file with the newest ineptkey again.

Btw. the aineptepub script of course doesn't work the the acsm files. These files are only download files for ADE. You have to at least open the foo.acsm file one time with ADE to download the real encrypted pdf.

It worked ok with the drm protected epub I've bought and downloaded from bol.com. This epub I could read with Adobe Digital Editions, but not on my Foxit eSlick e-reader (it does not support epubs-with-drm).
Thanks for this "how to"!

Because I read here no reactions on the "Error: problem decrytping session key" message, I will make a guess.
The Remove-ePub-drm-use-python-script.rar file includeds 2 epubs-with-drm. When I try to remove drm from these example files, I get the same error message.
My guess is that first-step ineptkey.pyw gets the key from Adobe Digital Editions (and not from the epubs). And that therefore second-step
ineptepub.pyw only is able to remove drm from your own ADE epubs and is not able te remove drm from the included sample epbus.

Hi,
I have also followed the instructions to the letter, on both an old XP machine and a Mac.
Everything seems to work, I get the adeptkey file, and then run ineptepub, chose the key, chose the folder that contains my adobe digital editions ebooks, chose an output folder, click decrypt and then nothing. Absolutely nothing happens.
Can anyone help?
Thanks

When I double click either the ineptkey.pyw or the ineptepub.pyw each gives a tiny glips of the "hourglass" then nothing. Am I supposed to have something else running?  ??
reply
01/14/2011 21:14:12
"Absolutely nothing happens."?
if you can create the adeptkey.der file, you can also remove drm from epub files.
But he ineptepub.pyw just remove drm from ADE protected epub, when the folder contains a epub not protected, the script will stop.
The ePub Drm Removal can skip the none-drm epub to remove all drm protected epub, you can download it to have a try!

This works! I couldn't open up an e-book, well I couldn't retrieve an e-book because the ascm file on my laptop wasn't able to retriev the info, so I downloaded the book on my desktop, retrieved the book there, transferred the epub book to my laptop, and lo, and behold, it opened up there, as well as on my e-reader. Amazing! Thank you, thank you. I intend to make a contribution to my library, as it's not my intent to use this work around to steal. I just wanted to be able to read things on my netbook, and now I can! Adobe, and my library couldn't find a fix for my inability to read DRM protected books on my laptop; now I can.

works fine without this error, so I guess it has something to do with how the script you links to gets the file list. Unfortunately, I don't speak Python.

I am running Python 2.7.1 on linux. (Seeing as python 2.6.X is no longer maintained by my (or any recent?) distro.

There is a bug in aineptepub.pyw that affects Mac OS X (and possibly other *nix). The script checks if it is a Windows or *nix system but always return a windows system.

The quick and dirty fix for Mac-users is to comment out line 319-324 and insert the following two lines:
        inpath=inpath+'/'
        outpath=outpath+'/'

The section should look like this when you are done.

        inpath=inpath+'/'
        outpath=outpath+'/'
#        if re.match('//',inpath):
#            inpath=inpath+'//'
#            outpath=outpath+'//'
#        else:
#            inpath=inpath+'\\'
#            outpath=outpath+'\\'

Firstly, the instructions fail to mention that the decrypted ebooks may only be read on certain readers.  I found ebook, free open sourced reader, worked best on android--but think is on many devices.

Secondly, some books work and other do not.   Trying epubee, the fail too, however, this program puts out a log.  I believe it said something didn't match a following part.  One book was 2 megs, and the garbage decrypted book was only one quarter of 2 megs.

I wonder if an alternative py would work on these failed books.
