Adobe ADEPT DRM for EPUB circumvented

You can actually get one off the ADE website. Look for sample books. Several of the epubs are drm'd

I've got the same problem as avid does. Windows 7 64bit. I run ineptkey.pyw and nothing, doesn't generate a .key file. I've tried the 64 and 32 bit versions of python and pycrypto (2.6 of python and 2.01 of pycrypto).

Any ideas anyone? Thanks!

Change this:

    userkey = userkey.decode('base64')
                  userkey = AES.new(keykey, AES.MODE_CBC).decrypt(userkey)

To this:

    userkey = userkey.decode('base64')
    userkey = AES.new(keykey, AES.MODE_CBC).decrypt(userkey)

The indent is causing the script not to run.

I installed ADE, Python2.6.4, the appropriate PyCrypto, all without problems on Windows XP home.
Downloaded an epub book with DRM free from Adobe, can see it fine in ADE.

Double click on ineptkey.pyw (both versions 2 and 3), and nothing happens - both with ADE running and closed.
Opened IDLE and ran the module there - gives me a Syntax error in both versions of ineptkey.
Any thoughts? I uninstalled and reinstalled all programs and the same result. I obviously haven't tried ineptepub as I don't yet have the key.
Thanks

PS - I am able to use dedrm for Mobi without problem - but I do that in Linux. Not sure what to do to troubleshoot this situation.

Question, I have used this method on epubs from the Sony store and from Shortcovers/Kobo. Then I exported them from Stanza into Word docs and saved them as HTML so I could remove the extra line breaks and other sloppy formatting. On both, the title of the book appeared at the end of every chapter, which was fine. But on Kobo, all those little page numbers did too and that is going to be a pain to edit out! Why did this happen on these pubs when it did not on the Sony ones? Any advice to easily remove them? It does make me reluctant to buy from Kobo again...

I have purchased ePub from Kobo when they were Shortcovers. I've never had an issue with page numbers showing up.

But when you are editing the ePub to fix the formatting, you don't need to load them into Word. The best thing to do is edit the CSS and that will fix most of the formatting problems (if not all). What I do is load the various files into Notepad++ along with the CSS and see what styles are used where so I can then go to the CSS and fix what needs fixing. Notepad++ supports tabs so I can load multiple files at the same time. I can even search/replace all the loaded files at the same time.

Did anybody try to use this with wine under linux?
ADE seems to run fine for me (I was able to download and view sucessfully a test drm'd pdf from booksonboard), but the key retrieval script failed with the error "Error: Incorrect padding".

I am aware that I will not be able to remove the drm from the pdf, but I assume the adeptkey script should work independtly of whether I have ePubs on my computer or not?

I'm getting this error when I try decrypt an epub I just bought: "Error: Error -3 while decompressing: invalid code lengths set".

The script does produce an epub, but some of the XHTML files in it seem to be missing. All the pictures are there, and most of the XHTMLs, but not all.

Now it's been a while since I've used the ineptepub.pyw file to decrypt an epub, I've been busy reading up on my backlog and more than a few wonderful public domain books from MobileRead, but I know it worked for me before.

I've also tried to decrypt this under Linux (I already have the adeptkey.der file). I downloaded the PyCrypto source code, compiled and installed it. The test suite seems to run fine. But I get the same error when I try to decrypt.

Anyone got any ideas? I have a DRM-laden epub and I don't want it to be DRM-laden.

[Valloric]

OK it seems three of the images in the original epub file are corrupt and the CRC check fails when extracting them, even with WinRAR. The script then stops processing other files in the archive.

Baaah, now I have to hack on the script to get it to decrypt the other files...

[peanutbuttah]

I have a question... I've successfully gone through all the steps and have a decrypted file saved. I moved it to my Kindle- the Documents folder- but it's just NOT there. I have made sure my Kindle is displaying "all my items".

It's definitely saved on my Kindle- I see it fine when opening the documents file while it's connected to my computer. I just can't see it when using the Kindle?

Any advice?

Have you converted the file to .mobi format? The Kindle won't read epub files natively. Happily they usually convert quickly, easily, and well - use Calibre (or mobigen/kindlegen if you aren't CLIphobic) to get something you can read on your Kindle.

No...? Haven't done this- I didn't realize it was neccesary! I have never used Calibre. So I can't just use a script of some kind to convert it?

You can use Calibre if you prefer a GUI, or grab kindlegen from here or here. The conversion process is quick, painless, and generally gives good output.

[peanutbuttah]

Thank you- I'll try Calibre. I hadn't realized I needed to do this.

Thanks again for your help!

Yup, that did it- and very painless. Thank you SO much!!

Note that if you prefer to do the conversion via a script, Calibre includes command-line scripts.
The one for book conversions is called ebook-convert.exe and is under the main Calibre directory.
This page describes how to use the various commands:
