Mobipocket Decoder Tool

[raymino]

Thanks JSWolf,

I do not run the Python command. It's just included in the screenshot in response to pilotbob's question. I don't think mobidedrm even runs fron the Python prompt. "not recognized".

I have looked at mobidedrm.py in both Notepad and Python Editor, and nothing jumps out as being wrong. Of course I know nothing of Python coding.

As for trying it without the quotes, I've done that many many times with the same result. I guess now I'll take a closer look at the downloaded text file and compare it to the mobidedrm.py file.

By the way, should I be using CMD or COMMAND from XP's Run?

Thanks,
Ray

CMD is the Run command to use to bring up the command prompt.

Thank you to wallcraft, JSWolf, pilotbob and bwaldron,

I was able to find version 3.0 of mobidedrm, but when running it from the command prompt, I still got the same disppointing results.

However when using "run" from within the Python Editor, and filling in the arguments in the second box, I finally got my dedrm'd file.

Conclusion: There's something wrong with my command prompt on my computer.

Anyway, I'm very grateful for all the help I got here.

At least it now works. Well done!

Did you actually install python? It sounds like the .py extension is not registered with python on your machine. When you browse the folder with the .py files in windows explorer does it list the file as python script or does it just say .py?

3.0! was this a typo or do I have to go searching for a new version again?

Hi pilotbob,

Yes, I have python installed. When I browse the folder, the file type for mobidedrm.py is listed as "Python File". It has the same icon as the Python applications, but their type is listed as "Application".

There is a fix to version 0.2 in post #76 of this thread.

I had to add Python to my Path command in order to run the scripts from the command prompt. When I installed Python it was not automatically added to the the Path command.

After a bit of fiddling around, I've been trying to get mobidedrm to work. I've taken the .02 script and made the tweaks described in post #76, but when I go to run it I hit a brick wall.

./MobiDeDRM.py:49: FutureWarning: hex/oct constants > sys.maxint will return positive values in Python 2.4 and up
  crc = (~binascii.crc32(s,-1))&0xFFFFFFFF
MobiDeDrm v0.02. Copyright (c) 2008 The Dark Reverser
Traceback (most recent call last):
  File "./MobiDeDRM.py", line 178, in ?
    file(outfile, 'wb').write(DrmStripper(data_file, pid).getResult())
  File "./MobiDeDRM.py", line 146, in __init__
    found_key = self.parseDRM(sect[drm_ptr:drm_ptr+drm_size], drm_count, pid)
  File "./MobiDeDRM.py", line 103, in parseDRM
    pid = pid.ljust(16,'\0')
TypeError: ljust() takes exactly 1 argument (2 given)

I don't know Python at all so I'm hoping someone here with a better idea than me can explain why the seemingly totally broken line 103 works for everyone else, but not for me. From the error it seems like a fundamental, fatal flaw in the code. Yet clearly that can't be the case since it's working for everyone else...

I'm running

Python 2.3.5 (#1, Mar 20 2005, 20:38:20) 
[GCC 3.3 20030304 (Apple Computer, Inc. build 1809)] on darwin

Anyone have any ideas?

[IceHand]

I think you need to have at least Python version 2.4 to get it running. Try upgrading it.

I copied the files across to my Leopard machine, which has Python 2.5.1 on it and tried again. No problems at all this time, worked flawlessly.
Thanks for your help.

If you're on Mac OS X, you might be interested in an Applescript wrapper I have for the decoder. I think it's OK to attach here, as without the MobiDeDRM.py script it can do nothing.

Once you copy the MobiDeDRM.py script into the package Resources folder, you can drag & drop files and/or folders onto the script and they'll all get decoded, you just need to enter your Mobipocket ID once. (& if you edit the AppleScript to include your code, not even that.)

Edited script to remove my Mobipocket ID, as that was causing confusion. Previous file had 15 downloads.

Edited script again to add quotes to PID on command line, as PIDs with $ in them cause problems on unix command lines.

Edited script again to add single quotes to PID on command line, as PIDs with $ in them cause problems on unix command lines. Also added in error reporting dialog if the python script returns text with "error" in it. Also added instructions for new fixes for 0.02 script to the readme.

Moved to own thread.

PDurrant - sorry if this is a terribly newbie question ... but where would I find a Mobipocket ID, if I had a mobipocket file I wished to run the script on, on my mac?

I should add that when I first click on the script you put up there, it asks me to navigate to a folder with a .prc file in it: I do that, select a file and up pops a window with some letters and numbers I assume are the associated mobipocket id. The mobidedrm v3 doesn't work at all, but the v2 does; however, the resultant file is zero k in size, so something's not quite right (I did rename the file to mobidedrm.py precisely inside the resources folder, yes).

I have MacPython 2.5 on my mac, which is a ppc. I note now I'm having similar problems to Seawolf - I recognised the

'./MobiDeDRM.py:49: FutureWarning: hex/oct constants > sys.maxint will return positive values in Python 2.4 and up
crc ='

bit from the error message I keep getting when I run the decoder.

The site where you bought the MOBI file will have the PID, typically in your account info. It is typically also displayable on any device running MobiPocket Reader. See Using the Mobipocket Reader at Fictionwise for example. The PID of each device is different, and any MOBI file can have up to 4 PIDs associated with it.
