Adobe ADEPT DRM for EPUB circumvented - Page 57

tetrachroma · 08-21-2010, 03:47 PM

The bulk processing epub decryption script (aineptepub 5.2) has been updated to be able to keep up with ILC release. This release can handle special directory cases and should work for the Mac as well.

Now it is possible to decrypt whole directories (of epubs) again. Enjoy ...

What about 5.2 is better than 4.1 (which never stopped working on whole directories)...?

As far as I can see it's mainly about Mac improvements (works without PyCrypto) and the regular expression recognition is improved. Try to decrypt a directory which contains a directory called 'bla.epub' ...

Thanks, joblack. Since I don't have a Mac and wouldn't know a "regular expression" (except maybe "Hello, how are you?"

), I'm probably fine with 4.1.

The old ainept script doesn't distinguish between files and directories. If you have a directory which is called something.epub the old script will stop.

Anyway, as I haven't written the improvements I cannot say if there are other improvements I can't see on the first glimpse.

Well, regular expressions (RE) are something different. One of them is 'ls *.epub' (or to be more precise only the '*' is a RE - > example for Mac/Linux) - in that case you want to see all files (and directories) with the epub extension.

I have an epub that I bought and sadly can't seem to shake the DRM. I get the adeptkey with no problem, however when I go to do the ineptepub I get this.... "error: ciphertext too large"

I made sure the pycrypto I got was for the correct python version, uninstalled and reinstalled, located different ineptkey and ineptepub's and tried those, all to the same error. And I cruised around google for awhile trying to find an answer and got no where.

So any help from anyone would be most appreciated, since I'm completely lost.

Thank you!

update: Nevermind I got it, I found different versions of ineptkey and ineptepub's that worked. Not sure why, but I'm not complaining.

Of course you would have known what (newer) version to use if you would have read in this forum thread for 5 minutes

Wow, you can read a 57 page thread in 5 minutes? Care to give us any tips?

Sure read from the last entries backwards ... I doubt you need more than 5 pages to find the required information.

On trying to run ineptpub_v5.2.pwy, I get the error message that the file name in the directory and header differ.

I tried unzipping the epub to another folder, and rezipping it with epub zip, where I got the error that it wasn't an adept epub. I checked, but the DRM hadn't been removed.

I tried with several books, same errors in each case.

Has anyone else run into this problem?

KevinH · 09-27-2010, 06:56 PM

Hi,

Yes, your zip archive has a central directory name that does not match the file name. This is a bug in how the epub was zipped up. It is actuyalloy a security issue but no one at Adobe seems to be interested in properly fixing it. This has nothing to do with DRM itself so I don't feel bad explaining.

Simply unzip it, fix the name of the file manually (to match its opf file name) if necessary, and ****properly**** re-zip it. My guess is you are simply not re-zipping it back up properly

The key to properly re-zipping it is to add the files to the zip archive in the proper order, without compression for some files, and obviously in the proper directories. You can find directions via Google how to do this by hand on the web.

There are tools available to make this easy for both Mac and Windows users.

On Windows - a simple google search gives me the following link. I have never tried it but it should work and if not, the author should be able to help.

On Mac's - a simple google search gives me the following and I have used this on my Mac OS X and it works wonderfully!

There are ways to do with with the command line unzip program by turning on the repair option for users of Linux.

Something here should properly fix the zip archive.

Okay, I just did something really, really stupid.

I updated my ineptkey - meant to hit " ineptepub.pyw" and hit "ineptkey.pyw" instead, updating it. Augh! Now my ineptepub script doesn't work! Can some kind person explain how to rectify this stupid mistake? I know it has something to do with the new ADE version. I'm afraid to mess with things too much without a plan in case I make things even worse.
Thanks for any help.

The latest ineptkey script should crack the latest Digital Editions. I haven't been blocking updates or anything and I've had no problems. I've been using ineptkey v4.3.

Leep · 10-03-2010, 08:29 PM

If you re-download the ebook, the newer copy should work with your new key.

cheers

Jane A · 10-03-2010, 09:17 PM

Thanks SpiderMatt and Leep. I gave you karma for your support.

The fix ended up being much easier than I thought and now I'm good to go. Redownloading the book file didn't work, but I upgraded everything to the latest version and now it all works again. I guess I ought to stop and think rather than panicking.

It just took me SO long to figure the script out in the first place that I thought I had a real problem on my hands.
