347ad3cc05 Update kindle on linux documentation
- ActivePython for x86 is gone, but using regular python, at least for the kindle decryption, works.
- The new kindle for pc hangs during wine installation, but the one presented by `winetricks kindle` works.
- The decryption keys must be manually obtained.
- vcrun2008 stops any available version of Kindle from being able to install.

I have only tested these steps for kindle for PC on linux, so these changes may step on some toes. However, it does seem the linux documentation needs updating nonetheless.

DeDRM_plugin.zip
================
This calibre plugin replaces many previously separate DRM removal plugins. Before you install this plugin, you should uninstall any older individual DRM removal plugins, e.g. K4MobiDeDRM. The exception is the obok plugin, which should not be removed.
This plugin will remove the DRM from
- Kindle ebooks (from Kindle for Mac/PC and eInk Kindles).
- Kindle ebooks (files from Kindle for Mac/PC* and eInk Kindles**).
- Barnes and Noble ePubs
- Adobe Digital Editions (v2.0.1*) ePubs (including Kobo and Google ePubs downloaded to ADE)
- Adobe Digital Editions (v2.0.1***) ePubs (including Kobo and Google ePubs downloaded to ADE)
- Adobe Digital Editions (v2.0.1) PDFs
- Mobipocket ebooks
- eReader PDB books
These tools do NOT work with kepubs downloaded using Kobo's desktop app (see the separate obok plugin) nor Apple's iBooks FairPlay DRM (see details about Requiem at the end of this file.)
* With Adobe Digital Editions 3.0 and later, Adobe have introduced a new, optional, DRM scheme. To avoid this new scheme, you should use Adobe Digital Editions 2.0.1. Some books are required to use the new DRM scheme and so will not download with ADE 2.0.1. If you still want such a book, you will need to use ADE 3.0 or later to download it, but you should remember that no tools to remove Adobe's new DRM scheme exist as of June 2016.
* With Kindle for PC/Mac 1.19 and later, Amazon included support for their new KFX format. While the tools now include a first attempt at supporting drm removal for KFX format, we recommend using Kindle for PC/Mac 1.17 or earlier which prevents downloads of the new format, as conversions from the olde KF8 format are likely to be more successful.
** Some later Kindles support Amazon's new KFX format. And some books download in a split azw3/azw6 format. For best results, instead of using files downloaded directly to your Kindle, download from Amazon's web site 'for transfer via USB'. This will give you an single file to import. See also the FAQ entry about this.

### A Recent Change to Kindle for PC/Kindle for Mac
Starting with version 1.19, Kindle for PC/Mac uses Amazon's new KFX format which these tools can't handle. Stick with version 1.17 or earlier. Kindle for PC 1.17 can be downloaded from https://s3.amazonaws.com/kindleforpc/44183/KindleForPC-installer-1.17.44183.exe and Kindle for Mac 1.17 can be downloaded from https://s3.amazonaws.com/kindleformac/44182/KindleForMac-44182.dmg
Starting with version 1.19, Kindle for PC/Mac uses Amazon's new KFX format which these tools can't handle. There are two options to get the older formats that the tools can decrypt. Either stick with version 1.17 or earlier, or modify the executable by changing a file name.
Version 1.17 of Kindle is are no longer available directly from Amazon, so you will need to search for the proper file name and find it on a third party site. The name is "KindleForPC-installer-1.17.44170.exe" for PC and "KindleForMac-44182.dmg" for Mac.
Verify the one of the following cryptographic hash values, using software of your choice, before installing the downloaded file in order to avoid viruses. If the hash does not match, delete the downloaded file and try again from another site.

You will need to go to the preferences and uncheck the auto update checkbox. Then download and install 1.17 over the top of the 1.19 installation. You'll also need to delete the KFX folders from your My Kindle Content folder.
A second possible solution is to use 1.19 or later, but disable KFX by renaming or disabling a necessary component of the application. This may or may not work on versions after 1.20. In a command window, enter the following commands when Kindle for PC/Mac is not running:
#### Windows
ren %localappdata%\Amazon\Kindle\application\renderer-test.exe renderer-test.xxx
PC Note: The renderer-test program may be in a different location in some Kindle for PC installations. If the rename command fails look in other folders, such as C:\Program Files\Amazon\Kindle.
#### Macintosh
chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test
Mac Note: If the chmod command fails with a permission error try again using sudo before chmod - sudo chmod [...]
After restarting the Kindle program any books previously downloaded in KFX format will no longer open. You will need to remove them from your device and re-download them. All future downloads will use the older Kindle formats instead of KFX although they will continue to be placed in one individual subdirectory per book.
#### Another Note on KFX
It now possible, but not easy, to convert books from KFX to other formats in calibre by installing the optional KFX Input plugin. The lack of automatic DRM removal makes this process difficult so it is not recommended unless there is no other alternative, such as for Indic language books only available in KFX. There is a windows-only KFX DRM rmeoval program in the repository, but not yet integrated into the tools.
#### Thanks
Thanks to jhowell for his investigations into KFX format and workarounds. Some of these instructions are from [his thread on the subject](https://www.mobileread.com/forums/showthread.php?t=283371) at MobileRead.

## Some of my books had their DRM removed, but some still say that they have DRM and will not convert.
There are several possible reasons why only some books get their DRM removed.
* You still dont have the DRM removal tools working correctly, but some of your books didnt have DRM in the first place.
* You added your books to calibre in large batches. For some unknown reason, sometimes calibre stops using the plugin after a while on a single import. Please see [this issue](https://github.com/apprenticeharper/DeDRM_tools/issues/??/) at Apprentice Harper's github repository. As a work-around, delete the books that still have DRM and import them into calibre in batches of twenty.
* Kindle only: It is a Topaz format book and contains some coding that the tools do not understand. You will need to get a log of the DeDRM attempt, and then create a [new issue at Apprentice Harper's github repository](https://github.com/apprenticeharper/DeDRM_tools/issues/), attaching the book and the log, so that the tools can be updated.
If you are still having problems with particular books, you will need to create a log of the DRM removal attempt for one of the problem books, and post that in a comment at Apprentice Alf's blog or in a new issue at Apprentice Harper's github repository.

Most Amazon Kindle ebooks are Mobipocket format ebooks, or the new KF8 format. However, some are in a format known as Topaz. The Topaz format is only used by Amazon. A Topaz ebook is a collections of glyphs and their positions on each page tagged with some additional information from that page including OCRed text (Optical Character Recognition generated Text) to allow searching, and some additional layout information. Each page of a Topaz ebook is effectively a description of an image of that page. To convert a Topaz ebook to another format is not easy as there is not a one-to-one mapping between glyphs and characters/fonts. To account for this, two different formats are generated by the DRM removal software. The first is an html description built from the OCRtext and images stored in the Topaz file (HTMLZ). This format is easily reflowed but may suffer from typical OCRtext errors including typos, garbled text, missing italics, missing bolds, etc. The second format uses the glyph and position information to create an accurate scalable vector graphics (SVG) image of each page of the book that can be viewed in web browsers that support svg images (Safari, Firefox 4 or later, etc). Additional conversion software can be used to convert these SVG images to an image only PDF file. The DeDRM calibre plugin only imports the HTMLZ versions of the Topaz ebook. The html version can be manually cleaned up and spell checked and then converted using Sigil/calibre to epubs, mobi ebooks, and etc.
## Are the tools open source? How can I be sure they are safe and not a trojan horse?
All the DRM removal tools hosted here are almost entirely scripts of one kind or another: Python, Applescript or Windows Batch files. So they are inherently open source, and open to inspection by everyone who downloads them. The source for any compiled pieces are provided right inside the tools themselves.
All the DRM removal tools hosted here are almost entirely scripts of one kind or another: Python, Applescript or Windows Batch files. So they are inherently open source, and open to inspection by everyone who downloads them.
There are some optional shared libraries (`*.dll`, `*.dylib`, and `*.so`) included for performance. The source for any compiled pieces are provided within `alfcrypto_src.zip`. If this is a concern either delete the binary files or manually rebuild them.
## What ebooks do these tools work on?
The tools linked from this blog remove DRM from PDF, ePub, kePub (Kobo), eReader, Kindle (Mobipocket, KF8, Print Replica and Topaz) format ebooks using Adobe Adept, Barnes & Noble, Amazon, Kobo and eReader DRM schemes.

* With Adobe Digital Editions 3.0 and later, Adobe have introduced a new, optional, DRM scheme. To avoid this new scheme, you should use Adobe Digital Editions 2.0.1. Some books are required to use the new DRM scheme and so will not download with ADE 2.0.1. If you still want such a book, you will need to use ADE 3.0 or later to download it, but you should remember that no tools to remove Adobe's new DRM scheme exist as of October 2016.
* With Kindle for PC/Mac 1.19 and later, Amazon included support for their new KFX format. While the tools now include a first attempt at supporting drm removal for KFX format, we recommend using Kindle for PC/Mac 1.17 or earlier which prevents downloads of the new format, as conversions from the olde KF8 format are likely to be more successful.
** Some later Kindles support Amazon's new KFX format. And some books download in a split azw3/azw6 format. For best results, instead of using files downloaded directly to your Kindle, download from Amazon's web site 'for transfer via USB'. This will give you an single file to import. See also the FAQ entry about this.

ActiveState's Active Python 2.7 Community Edition for Windowscan be downloaded for free from:

We do **NOT** recommend the version of Python from python.org as it is missing various Windows specific libraries, does not install the Tk Widget kit (for graphical user interfaces) by default, and does not properly update the system PATH environment variable. Therefore using the default python.org build on Windows is simply an exercise in frustration for most Windows users.
Note that currently (October 2016) ActiveState Python puts the tcl library in the wrong place, and it needs to be manually moved. See this thread at activestate.com for the latest information: https://community.activestate.com/node/19090
