KindleBooks (Originally called K4MobiDeDRM and Topaz_Tools)
|
||||
|
||||
This tools combines functionality of MobiDeDRM with that of K4PCDeDRM, K4MDeDRM, and K4DeDRM. Effectively, it provides one-stop shopping for all your Mobipocket, Kindle for iPhone/iPad/iPodTouch, Kindle for PC, and Kindle for Mac needs and should work for both Mobi and Topaz ebooks.
|
||||
|
||||
Preliminary Steps:
|
||||
|
||||
1. Make sure you have Python 2.X installed (32 bit) and properly set as part of your SYSTEM PATH environment variable (On Windows I recommend ActiveState's ActivePython. See their web pages for instructions on how to install and how to properly set your PATH). On Mac OSX 10.6 everything you need is already installed.
|
||||
|
||||
|
||||
****
|
||||
Please Note: If you a happy user of MobiDeDRM, K4DeDRM, K4PCDeDRM, or K4MUnswindle, please continue to use these programs as there is no additional capability provided by this tool over the others. In the long run, if you have problems with any of those tools, you might want to try this one as it will continue under development eventually replacing all of those tools.
|
||||
****
|
||||
|
||||
Instructions:
|
||||
|
||||
1. double-click on KindleBooks.pyw
|
||||
|
||||
2. In the window that opens:
|
||||
hit the first '...' button to locate your DRM Kindle-style ebook
|
||||
|
||||
3. Then hit the second '...' button to select an output directory for the unlocked file
|
||||
|
||||
4. If you have multiple Kindle.Info files and would like to use one specific one, please hit the third "...' button to select it. Note, if you only have one Kindle.Info file (like most users) this can and should be left blank.
|
||||
|
||||
5. Then add in any PIDs you need from KindleV1, Kindle for iPhone/iPad/iPodTouch, or other single PID devices to the provided box as a comma separated list of 10 digit PID numbers. If this is a Kindle for Mac or a Kindle for PC book then you can leave this box blank
|
||||
|
||||
|
||||
6. If you have standalone Kindles, add in any 16 digit Serial Numbers as a comma separated list. If this is a Kindle for Mac or a Kindle for PC book then you can leave this box blank
|
||||
|
||||
7. hit the 'Start' button
|
||||
|
||||
After a short delay, you should see progress in the Conversion Log window indicating is the unlocking was a success or failure.
|
||||
|
||||
|
||||
|
||||
If your book was a normal Mobi style ebook:
|
||||
If successful, you should see a "_nodrm" named version Mobi ebook.
|
||||
If not please examine the Conversion Log window for any errors.
|
||||
|
||||
|
||||
|
||||
If your book was actually a Topaz book:
|
||||
|
||||
Please note that Topaz is most similar to a poor man's image only PDF in style. It has glyphs and x,y positions, ocrText used just for searching, that describe the image each page all encoded into a binary xml-like set of files.
|
||||
|
||||
If successful, you will have 3 zip archives created.
|
||||
|
||||
1. The first is BOOKNAME_nodrm.zip.
|
||||
You can import this into calibre as is or unzip it and edit the book.html file you find inside. To create the book.html, Amazon's ocrText is combined with other information to recreate as closely as possible what the original book looked like. Unfortunately most bolding, italics is lost. Also, Amazon's ocrText can be absolutely horrible at times. Much work will be needed to clean up and correct Topaz books.
|
||||
|
||||
2. The second is BOOKNAME_SVG.zip
|
||||
You can also import this into calibre or unzip it and open the indexsvg.xhtml file in any good Browser (Safari, Firefox, etc). This zip contains a set of svg images (one for each pages is created) and it shows the page exactly how it appeared. This zip can be used to create an image only pdf file via post conversion.
|
||||
|
||||
3. The third is BOOKNAME_XML.zip
|
||||
This is a zip archive of the decrypted and translated xml-like descriptions of each page and can be archived/saved in case later code can do a better job converting these files. These are exactly what a Topaz books guts are. You should take a look at them in any text editor to see what they look like.
|
||||
|
||||
If the Topaz book conversion is not successful, a large _DEBUG.zip archive of all of the pieces is created and this can examined along with the Conversion Log window contents to determine the cause of the error and hopefully get it fixed in the next release.

# Changelog
|
||||
# 0.01 - Initial version
|
||||
# 0.02 - Huffdic compressed books were not properly decrypted
|
||||
# 0.03 - Wasn't checking MOBI header length
|
||||
# 0.04 - Wasn't sanity checking size of data record
|
||||
# 0.05 - It seems that the extra data flags take two bytes not four
|
||||
# 0.06 - And that low bit does mean something after all :-)
|
||||
# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
|
||||
# 0.08 - ...and also not in Mobi header version < 6
|
||||
# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
|
||||
# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
|
||||
# import filter it works when importing unencrypted files.
|
||||
# Also now handles encrypted files that don't need a specific PID.
|
||||
# 0.11 - use autoflushed stdout and proper return values
|
||||
# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
|
||||
# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
|
||||
# and extra blank lines, converted CR/LF pairs at ends of each line,
|
||||
# and other cosmetic fixes.
|
||||
# 0.14 - Working out when the extra data flags are present has been problematic
|
||||
# Versions 7 through 9 have tried to tweak the conditions, but have been
|
||||
# only partially successful. Closer examination of lots of sample
|
||||
# files reveals that a confusion has arisen because trailing data entries
|
||||
# are not encrypted, but it turns out that the multibyte entries
|
||||
# in utf8 file are encrypted. (Although neither kind gets compressed.)
|
||||
# This knowledge leads to a simplification of the test for the
|
||||
# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
|
||||
# 0.15 - Now outputs 'heartbeat', and is also quicker for long files.
|
||||
# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
|
||||
# 0.17 - added modifications to support its use as an imported python module
|
||||
# both inside calibre and also in other places (ie K4DeDRM tools)
|
||||
# 0.17a- disabled the standalone plugin feature since a plugin can not import
|
||||
# a plugin
|
||||
# 0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
|
||||
# Removed the disabled Calibre plug-in code
|
||||
# Permit use of 8-digit PIDs
|
||||
# 0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
|
||||
# 0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
|
||||
# 0.21 - Added support for multiple pids
|
||||
# 0.22 - revised structure to hold MobiBook as a class to allow an extended interface
