ineptepub.pyw error: Problem decrypting session key

 

hello everyone,

I had no problems installing and then removing the DRM from epub and PDF files, however, sometimes this method does not work. I get an error message saying 'Error: problem decrypting session key'. Does anyone know how to get around this?

Many thanks in advance!

I am getting the same problem as the last post for the two books I have tried to remove DRM from:

I followed all the procedures described originally and every thing works fine until after selecting the files in the dialog box for input and output and clicking decrypt I get the error: Per an earlier post on the same issue I unzipped one of the EPUB files I was attempting to remove the DRM from and found this code as the first line of the rights.xml file:
I am now at a loss as to what to try.

If you try to remove DRM from B&N ebooks, see the following thread:
How to remove DRM protection from B&N (Barnes & Noble) EPUB ebooks


Another problem is that ADE 1.7.2 changed how the key information is stored. If you have adeptkey.der generated prior to ADE 1.7.2, you can use it to remove DRM protection from ebooks downloaded before updating ADE to version 1.7.2.

You can also re-download EPUB ebooks that were downloaded when using ADE prior to 1.7.2, then generate new adeptkey.der with inteptkey v.4.3 or ineptkeymac v.1. After that you can remove DRM protection using one ineptepub or aineptepub.

It is recommended to use ADE 1.7.2 and re-download ebooks (instead of downgrading ADE to v.1.7.1.)

Yeah, I had already found that suggested fix from another source. Unfortunately I went through the suggested procedure of removing the latest version of Digital Editions, installing the older version, and registering that. I then generated the new key file, but still encountered the same error: as before. It was not a Barnes and Noble EPUB book; it is one I just recently purchased from Sony. So unless there is something else I’m doing wrong I guess I am out of luck. Thanks for your attempt to help though.

Slight rant. I actually have no problem with DRM as a means to protect intellectual property rights to prevent others distributing free copies of copyright material. What I object to is that if I buy an ebook from Sony I can view that on a Sony ebook viewer, but not on any other device. So if I replace my Sony with, say a Kindle, I have to buy the same book again. If this keeps up with each ebook viewer manufacturer having a proprietary format for ebooks that can only be viewed on their device it will severely restrict the growth for all.

Please try to do the following again. I haven't seen any problems with the following solution yet:

1. Uninstall the new version of ADE
2. Delete the ADEPT folder in the Registry.
   HKEY_CURRENT_USER>Software>Adobe>ADEPT
3. Delete the "My Digital Editions" folder in "My Documents".
4. Reboot computer.
5. Re-install the old version provided in the link below
   
   Code:

6. Reactivate ADE.
7. Run the Ineptkey again to obtain the Adeptkey.der.
8. Then you should be good to go.

Some users even tried the update again, and still were able to remove DRM.

In frustration I put this whole business aside for a few days. The break inspired me to fresh thinking about the problem. The epub books I was having a problem with I had downloaded some time ago onto my previous computer. When I bought my new computer I just copied the files over. So anyway I deleted these old files and then downloaded them once more from my Sony ebook store account. Problem solved. The procedure worked perfectly to strip the DRM. Thanks so much for your help. Now if I could just remove the DRM from a couple of books I have in PDF format. ;).

I used Solution #1 without success. However, when I went back and used Solution #2 (involving editing the registry), it worked like a charm. You can even upgrade back to 1.7.2 after retrieving your key in 1.7.1 so you can download new material. As long as you don't try and grab your key again, all is ducky. I made several copies of my key and scattered them around various machines and drives just so that I would always have available in case I did something stupid, like double-clicking the wrong file. :)

While this thread has been very helpful in some regards, I am still having one problem.

I am going for Solution 2 in this case.

When I run ineptepub.pyw or ineptpdf.pyw, the input section does not recognize any of my files which I need to break the DRM of!

Am I doing something wrong? Do the files I need 'decrypting' need to be in a specific folder?

Re: ineptepub.pyw error: Problem decrypting session key

 

Where did you buy your ebooks and in what format?

Re: ineptepub.pyw error: Problem decrypting session key

 

Sorry for the delay on this.

I bought these books from infibeam.com, these are Adobe Digital Editions and epubs.

Hope this is sufficient information.

Thanks, anyway!
