Mobipocket Decoder Tool

Nate the great · 02-08-2008, 11:35 PM

I apologize in advance for the frustration this will cause.

There is a new DRM stripper for Mobipocket ebooks out on the web. It's written in Python, and it works. Unfortunately, I can't help you find it.

Our forum policy on DRM removal tools is that I can mention the name, and give vague instruction on how to find it. I can't provide a link to the tool. Unfortunately, the new tool doesn't have a name yet. In fact, it hasn't been released or announced or anything. What I have is not the tool, but the source file. A link to the source was posted by a member. The source file is currently on www.pastebin.com. Look there if you want, I doubt you will find it.

So here I am. I can't tell you the name or location, just that it exist. That's not very helpful, I know. I'm sorry.

P.S. I like our forum policy. This is the first time that I've been blocked from helping people.

I've tried it on the freebie 'Around the world in 80 days' from Fictionwise & it works quite well.

It is interesting that all this takes is a 150 line python script.

Based on the source code, it should be called mobidedrm.py:

Code:

print  "MobiDeDrm v0.01. Copyright (c) 2008 The Dark Reverser"

There's a new tool for all mobipocket users out there called MobiDeDrm. It's written in Python, and can apparently be found through a google search.

That's quite frustrating : I'm apparently not that good at googling hidden stuff

tompe · 02-09-2008, 06:50 AM

So that means that the MobiPocket format now has the same status as the lit format. It is a format you can buy things in since you then can convert it to anything else. So now the Sony Reader definitely has most books available to buy.

Could you give us mobi decoder rings instead ? if you could put them inside cereal boxes that would be perfect. also then maybe we could all have secret identities and wear capes while making (or un-drm-ing) ebooks. that would make me really happy.

Google "pastebin MobiDeDrm". All you get is the source code for a Python program, so you may have found it without realizing what you had.

The last time a Mobipocket decoder was available, it was shut down pretty quickly with the threat of a lawsuit, so don't expect this one to be available for a long time.

You won't find it searching through the link that Nate provided, but there are other clues in his posting that will help you figure out where to look. It took me about 30 minutes last night to figure it out.

The decoder works a treat! And it's funny, but I feel like my DRM Mobipocket books are worth more to me now and I'm more willing to spend the money on them because now I know I will not be constrained in using them - I never realized how much I hate DRM.

More clues please... I must be stupid...

But wasn't that because copyrighted code was used? In what respect is this program different from ConvertLit that has not been removed?

DMcCunney · 02-09-2008, 11:16 AM

The magic word "m40582493" might help in locating it...

Anemic Oaks posting was a pretty big clue for me (thanks Anemic Oaks).

I don't know much about the specific reason the other decoder was removed. This decoder is really not a program at all. It is lines and lines of Python code that is not compiled into a program, so you'll need to install Python to your computer (http://www.activestate.com/Products/activepython/) before you can run it. Nonetheless once you connect all the dots, it is fairly easy to run and works quite well. It does not extract the HTML files like converlit, it only removes the DRM.

Well, it is a program. It is just not in a form that is directly executable. To execute the program you have to run an intepreter.

convertLit as i understand it constists of two part. One part that only remove the drm. And one part that pakes a drm free lit file and explode it.

This also seems to work on AZW files by the way:

Code:

mobidedrm infile.azw outfile.mobi KindlePID

Amazon.com has got out of the e-book selling business before, leaving its e-book buyers with no way to move e-books to new devices. So it is comforting to know that there is a work around (at least for AWZ books) if they decide that there won't be a Kindle II or that Kindle I e-books are not transferable to Kindle IIs.
