skindle - remove DRM from KindleForPC ebooks (mobi and topaz)

Try to ask the developer of skindle.

You can also try to use other tools, for example: MobiDeDRM.py.

I checked skindle and a few things that are different for sure:

The kindle.info is located here:

/Users/x/Library/Application Support/Amazon/Kindle For Mac/storage/.kindle-info

string_32 is the same, but string_64 is different. The correct string is:

"ZB0bYyc1xDdW2wEV3Ff7KkPpL8UuGA4gz-Tme9Nn_tHh5SvXCsIiR6rJjQaqlOoM"

From there I just have no clue what they use instead of CryptUnprotectData. The other info was available using lsof/opensnoop and strings.

Try to use the following:
DeDRM AppleScript for Mac OS X 10.5, 10.6

Can you walk me through how to do the MobiDeDrm? I don't understand how to do that. It took me 2 days to figure how to do skindle . I have read alot about using it but cant figure it out exactly??!!


Ok was finally able to get Python and unswindle to work. Thanks for help!!

skindle -i xxx.azw -o xxx.mobi
Attempting to locate kindle.info
Found kindle.info location
Using UserName = "Void"
Using SystemDrive = "C:\"
Using VolumeSerialNumber = "NNNNNNNNNN"
Device PID: XXXXNXXX
PID for xxx is: YYYyYyyY
Didn't find PID magic numbers in record
Found a DRM key!
634702b65r3829g3
Parse Error : Failed payload read of record color: 1 offset 0x4de592:0x0

and then windows sends a pop-up telling me skindle has made an error and has to close. This has happened several times already.

Anybody knows what I'm doing wrong, or how this could be solved?

Thank you very much in advance,

Simon

Did you manage to get to the bottom of this?

I've got the same problem (with a slightly different code at the end "offset 0xcd24fc:0x0"). I've got a Sony Reader and bought a book that was only available from Kindle Store.

Seeing as beating the drm of Adobe Digital Editions had been so easy i just assumed that i would be able to figure this out too. It's been driving me up the wall tho!

Any help from anyone would be greatly appreciated. I am running skindle from the command prompt on a Vista machine.

What do you mean by "using this"? DeDRM AppleScript for Mac OS X 10.5, 10.6? unswindle? topazscripts?

I've tried multiple tools (Skindle, Unswindle etc) and I'm getting partially corrupted mobi output. I can't seem to find where to post a bug report so I'm posting here:

Check this thread for more details:

Odd partially corrupted output: AZW to MOBI

I am able to convert the ebook, according to the:
Success! Enjoy!

Done.

entries as stated by the skindle gui tool. After that I am able to open the new file in Kindle for PC but cannot open it with mobireader. It gives me a "Error while adding this file to the library" and then a "file corrupt" error. Any thoughts? Thanks.
