Inept PDF Plugin - ineptpdf_vXX_plugin.zip
|
||||
Requires Calibre version 0.6.44 or higher.
|
||||
|
||||
All credit given to IHeartCabbages for the original standalone scripts.
|
||||
I had the much easier job of converting them to a Calibre plugin.
|
||||
|
||||
This plugin is meant to decrypt Adobe Digital Edition PDFs that are protected with Adobe's Adept encryption. It is meant to function without having to install any dependencies... other than having Calibre installed, of course. It will still work if you have Python, PyCrypto and/or OpenSSL already installed, but they aren't necessary.
|
||||
|
||||
Installation:
|
||||
|
||||
Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file (ineptpdf_vXX_plugin.zip) and click the 'Add' button. you're done.
|
||||
|
||||
Configuration:
|
||||
|
||||
When first run, the plugin will attempt to find your Adobe Digital Editions installation (on Windows and Mac OS's). If successful, it will create an 'adeptkey.der' file and save it in Calibre's configuration directory. It will use that file on subsequent runs. If there are already '*.der' files in the directory, the plugin won't attempt to
|
||||
find the Adobe Digital Editions installation installation.
|
||||
|
||||
So if you have Adobe Digital Editions installation installed on the same machine as Calibre... you are ready to go. If not... keep reading.
|
||||
|
||||
If you already have keyfiles generated with I <3 Cabbages' ineptkey.pyw script, you can put those keyfiles in Calibre's configuration directory. The easiest way to find the correct directory is to go to Calibre's Preferences page... click on the 'Miscellaneous' button (looks like a gear), and then click the 'Open Calibre configuration directory' button. Paste your keyfiles in there. Just make sure that
|
||||
they have different names and are saved with the '.der' extension (like the ineptkey script produces). This directory isn't touched when upgrading Calibre, so it's quite safe to leave them there.
|
||||
|
||||
Since there is no Linux version of Adobe Digital Editions, Linux users will have to obtain a keyfile through other methods and put the file in Calibre's configuration directory.
|
||||
|
||||
All keyfiles with a '.der' extension found in Calibre's configuration directory will be used to attempt to decrypt a book.
|
||||
|
||||
** NOTE ** There is no plugin customization data for the Inept PDF plugin.
|
||||
|
||||
Troubleshooting:
|
||||
|
||||
If you find that it's not working for you (imported PDFs still have DRM), you can save a lot of time and trouble by trying to add the PDF to Calibre with the command line tools. This will print out a lot of helpful debugging info that can be copied into any online help requests. I'm going to ask you to do it first, anyway, so you might
|
||||
as well get used to it. ;)
|
||||
|
||||
Open a command prompt (terminal) and change to the directory where the ebook you're trying to import resides. Then type the command "calibredb add your_ebook.pdf". Don't type the quotes and obviously change the 'your_ebook.pdf' to whatever the filename of your book is. Copy the resulting output and paste it into any online help request you make.
|
||||
|
||||
** Note: the Mac version of Calibre doesn't install the command line tools by default. If you go to the 'Preferences' page and click on the miscellaneous button, you'll see the option to install the command line tools.

Plugin for K4PC, K4Mac and Mobi Books
|

Plugin for K4PC, K4Mac, standalone Kindles, Mobi Books, and for Devices with Fixed PIDs.

This plugin supersedes MobiDeDRM, K4DeDRM, and K4PCDeDRM plugins. If you install this plugin, those plugins can be safely removed.
|

This plugin is meant to convert "Kindle for PC", "Kindle for Mac" and "Mobi" ebooks with DRM to unlocked Mobi files. Calibre can then convert them to whatever format you desire. It is meant to function without having to install any dependencies except for Calibre being on your same machine and in the same account as your "Kindle for PC" or "Kindle for Mac" application if you are going to remove the DRM from those types of books.

Highlight the plugin (K4MobiDeDRM under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. Enter a comma separated list of your 10 digit PIDs. This is not needed if you only want to decode "Kindle for PC" or "Kindle for Mac" books.

"""Hashing algorithms
|

Hash functions take arbitrary strings as input, and produce an output
|
||||
of fixed size that is dependent on the input; it should never be
|
||||
possible to derive the input data given only the hash function's
|
||||
output. Hash functions can be used simply as a checksum, or, in
|
||||
association with a public-key algorithm, can be used to implement
|
||||
digital signatures.

247, "API for Cryptographic Hash Functions".

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.
