Ignoble Epub DeDRM - ignobleepub_v01.6_plugin.zip
|
||||
|
||||
All credit given to I♥Cabbages for the original standalone scripts.
|
||||
I had the much easier job of converting them to a calibre plugin.
|
||||
|
||||
This plugin is meant to decrypt Barnes & Noble Epubs 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 and PyCrypto already installed, but they aren't necessary.
|
||||
|
||||
|
||||
Installation:
|
||||
|
||||
Go to calibre's Preferences page. Do **NOT** select "Get plugins to enhance calibre" as this is reserved for "official" calibre plugins, instead select "Change calibre behavior". Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file (ignobleepub_vXX_plugin.zip) and click the 'Add' button. you're done.
|
||||
|
||||
Please note: calibre does not provide any immediate feedback to indicate that adding the plugin was a success. You can always click on the File-Type plugins to see if the plugin was added.
|
||||
|
||||
|
||||
Configuration:
|
||||
|
||||
1) The easiest way to configure the plugin is to enter your name (Barnes & Noble account name) and credit card number (the one used to purchase the books) into the plugin's customization window. It's the same info you would enter into the ignoblekeygen script. Highlight the plugin (Ignoble Epub DeDRM) and click the "Customize Plugin" button on calibre's Preferences->Plugins page. Enter the name and credit card number separated by a comma: Your Name,1234123412341234
|
||||
|
||||
If you've purchased books with more than one credit card, separate that other info with a colon: Your Name,1234123412341234:Other Name,2345234523452345
|
||||
|
||||
** NOTE ** The above method is your only option if you don't have/can't run the original I♥Cabbages scripts on your particular machine. Your credit card number will be on display in calibre's Plugin configuration page when using the above method. If other people have access to your computer, you may want to use the second configuration method below.
|
||||
|
||||
|
||||
2) If you already have keyfiles generated with I <3 Cabbages' ignoblekeygen.pyw script, you can put those keyfiles into 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 '.b64' extension (like the ignoblekeygen script produces). This directory isn't touched when upgrading calibre, so it's quite safe to leave them there.
|
||||
|
||||
All keyfiles from method 2 and all data entered from method 1 will be used to attempt to decrypt a book. You can use method 1 or method 2, or a combination of both.
|
||||
|
||||
|
||||
Troubleshooting:
|
||||
|
||||
If you find that it's not working for you (imported epubs still have DRM), you can save a lot of time and trouble by trying to add the epub 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.epub". Don't type the quotes and obviously change the 'your_ebook.epub' 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.

Inept Epub DeDRM - ineptepub_vXX_plugin.zip
|
||||
Requires Calibre version 0.6.44 or higher.
|
||||
|
||||
All credit given to I <3 Cabbages 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 Epubs 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 and PyCrypto already installed, but they aren't necessary.

|
||||
|
||||
|
||||
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.

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.

K4MobiDeDRM_v04.5_plugin.zip
|
||||
|
||||
Credit given to The Dark Reverser for the original standalone script. Credit also to the many people who have updated and expanded that script since then.
|
||||
|
||||
Plugin for K4PC, K4Mac, eInk Kindles and Mobipocket.
|
||||
|
||||
This plugin supersedes MobiDeDRM, K4DeDRM, and K4PCDeDRM and K4X plugins. If you install this plugin, those plugins can be safely removed.
|
||||
|
||||
This plugin is meant to remove the DRM from .prc, .mobi, .azw, .azw1, .azw3, .azw4 and .tpz ebooks. 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.
|
||||
|
||||
|
||||
Installation:
|
||||
|
||||
Go to Calibre's Preferences page. Do **NOT** select "Get Plugins to enhance calibre" as this is reserved for official calibre plugins", instead select "Change calibre behavior". Under "Advanced" click on the on the Plugins button. Click on the "Load plugin from file" button at the bottom of the screen. Use the file dialog button to select the plugin's zip file (K4MobiDeDRM_vXX_plugin.zip) and click the "Add" (or it may say "Open" button. Then click on the "Yes" button in the warning dialog that appears. A Confirmation dialog appears that says the plugin has been installed.
|
||||
|
||||
|
||||
Configuration:
|
||||
|
||||
Highlight the plugin (K4MobiDeDRM under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. If you have an eInk Kindle enter the 16 digit serial number (these typically begin "B0..."). If you have more than one eInk Kindle, you can enter multiple serial numbers separated by commas (no spaces). If you have Mobipocket books, enter your 10 digit PID. If you have more than one PID, separate them with commax (no spaces).
|
||||
|
||||
This configuration step is not needed if you only want to decode "Kindle for PC" or "Kindle for Mac" books.
|
||||
|
||||
|
||||
Linux Systems Only:
|
||||
|
||||
If you install Kindle for PC in Wine, the plugin should be able to decode files from that Kindle for PC installation under Wine. You might need to enter a Wine Prefix if it's not already set in your Environment variables.
|
||||
|
||||
|
||||
Troubleshooting:
|
||||
|
||||
If you find that it's not working for you, you can save a lot of time and trouble by trying to add the DRMed ebook 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_file". Don't type the quotes and obviously change the 'your_ebook_file' to whatever the filename of your book is (including any file name extension like .azw). Copy the resulting output and paste it into any online help request you make.

Plugin for K4PC, K4Mac, standalone Kindles, Mobi Books, and for Devices with Fixed PIDs.
|
||||
|
||||
This plugin supersedes MobiDeDRM, K4DeDRM, and K4PCDeDRM and K4X plugins. If you install this plugin, those plugins can be safely removed.
|
||||
|
||||
|
||||
|
||||
This plugin is meant to remove the DRM from .prc, .azw, .azw1, and .tpz ebooks. 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.
|
||||
|
||||
|
||||
|
||||
Installation:
|
||||
|
||||
Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file (K4MobiDeDRM_vXX_plugin.zip) and click the 'Add' button. You're done.
|
||||
|
||||
Please note: Calibre does not provide any immediate feedback to indicate that adding the plugin was a success. You can always click on the File-Type plugins to see if the plugin was added.
|
||||
|
||||
|
||||
|
||||
Configuration:
|
||||
|
||||
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. Include in this list (again separated by commas) any 16 digit serial numbers the standalone Kindles you may have (these typically begin "B0...") This is not needed if you only want to decode "Kindle for PC" or "Kindle for Mac" books.

eReader PDB2PML - eReaderPDB2PML_vXX_plugin.zip
|
||||
|
||||
All credit given to The Dark Reverser for the original standalone script. I had the much easier job of converting it to a Calibre plugin.
|
||||
|
||||
This plugin is meant to convert secure Ereader files (PDB) to unsecured PMLZ files. Calibre can then convert it to whatever format you desire. It is meant to function without having to install any dependencies... other than having Calibre installed, of course. I've included the psyco libraries (compiled for each platform) for speed. If your system can use them, great! Otherwise, they won't be used and things will just work slower.
|
||||
|
||||
Installation:
|
||||
Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file (eReaderPDB2PML_vXX_plugin.zip) and click the 'Add' button. You're done.
|
||||

|
||||
|
||||
Configuration:
|
||||
Highlight the plugin (eReader PDB 2 PML under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. Enter your name and last 8 digits of the credit card number separated by a comma: Your Name,12341234
|
||||
|
||||
If you've purchased books with more than one credit card, separate the info with a colon: Your Name,12341234:Other Name,23452345 (NOTE: Do NOT put quotes around your name like you do with the original script!!)
|
||||
|
||||
Troubleshooting:
|
||||
If you find that it's not working for you (imported pdb's are not converted to pmlz format), you can save a lot of time and trouble by trying to add the pdb 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.pdb". Don't type the quotes and obviously change the 'your_ebook.pdb' 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.

|

\cf0 DeDRM is an application that packs all of the python drm-removal software into one easy to use program that remembers preferences and settings.\
|
||||
It works without manual configuration with Kindle for Mac ebooks and Adobe Adept ePub and PDF ebooks.\
|
||||
\
|
||||
To remove the DRM of Kindle ebooks from eInk Kindles, eReader pdb ebooks, Barnes and Noble ePubs, or Mobipocket ebooks, you must first run DeDRM application (by double-clicking it) and set some additional Preferences including:\
|
||||
\
|
||||
Kindle (not Kindle Fire): 16 digit Serial Number\
|
||||
Barnes & Noble ePub: Name and CC number or key file (bnepubkey.b64)\
|
||||
eReader Social DRM: Name and last 8 digits of CC number\
|
||||
Mobipocket: 10 digit PID\
|
||||
\
|
||||
A final preference is the destination folder for the DRM-free copies of your ebooks that the application produces. This can be either the same folder as the original ebook, or a folder of your choice.\
|
||||
\
|
||||
Once these preferences have been set, you can drag and drop ebooks (or folders of ebooks) onto the DeDRM droplet to remove the DRM.\
|
||||
\
|
||||
This program requires Mac OS X 10.5 or above. \

\b \cf0 Installation
|
||||

|
||||
Drag the DeDRM application from from tools_v5.3\\DeDRM_Applications\\Macintosh (the location of this ReadMe) to your Applications folder, or anywhere else you find convenient.\
|
||||
\
|
||||
\
|
||||
|
||||
\b Use
|
||||
\b0 \
|
||||
1. To set the preferences, double-click the application and follow the instructions in the dialogs.\
|
||||
2. Drag & Drop DRMed ebooks or folders of DRMed ebooks onto the application icon when it is not running.\

DeDRM_WinApp is a pure python drag and drop application that allows users to drag and drop ebooks or folders of ebooks onto theDeDRM_Drop_Target to have the DRM removed. It repackages the"tools" python software in one easy to use program.
|

DeDRM_v5.3_WinApp is a pure python drag and drop application that allows users to drag and drop ebooks or folders of ebooks onto the DeDRM_Drop_Target to have the DRM removed. It repackages the"tools" python software in one easy to use program that remembers preferences and settings.
|
||||
|
||||
It should work out of the box with Kindle for PC ebooks and Adobe Adept epub and pdf ebooks.
|
||||
|
||||
To remove the DRM from standalone Kindle ebooks, eReader pdb ebooks, Barnes and Noble epubs, and Mobipocket ebooks requires the user to double-click the DeDRM_Drop_Target and set some additional Preferences including:
|
||||
|
||||
Kindle 16 digit Serial Number
|
||||
Barnes & Noble key files (bnepubkey.b64)
|
||||
eReader Social DRM: (Name:Last 8 digits of CC number)
|
||||
MobiPocket, Kindle for iPhone/iPad/iPodTouch 10 digit PID
|
||||
eInk Kindle: 16 digit Serial Number
|
||||
Barnes & Noble: key file (bnepubkey.b64)
|
||||
eReader Social DRM: Name:Last 8 digits of CC number
|
||||
MobiPocket: 10 digit PID
|
||||
|
||||
Once these preferences have been set, the user can simply drag and drop ebooks onto the DeDRM_Drop_Target to remove the DRM.
|
||||
|
||||
This program requires that the proper 32 bit version of Python 2.X (tested with Python 2.5 through Python 2.7) and PyCrypto be installed on your computer before it will work. See below for where to get theese programs for Windows.
|
||||
|
||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
1. Download the latest DeDRM_WinApp_vx.x.zip and fully Extract its contents.
|
||||
1. In tools_v5.3\DeDRM_Applications\Windows, right click on DeDRM_5.3_Win.zip and fully extract its contents using "Extract All...", saving to your "My Documents" folder.
|
||||
|
||||
2. Move the resulting DeDRM_WinApp_vX.X folder to whereever you keep you other programs.
|
||||
(I typically use an "Applications" folder inside of my home directory)
|
||||
|
||||
3. Open the folder, and create a short-cut to DeDRM_Drop_Target and move that short-cut to your Desktop.
|
||||
|
||||
4. To set the preferences simply double-click on your just created short-cut.
|
||||
2. Open the DeDRM_5.3_Win folder you've just created, and make a short-cut of the DeDRM_Drop_Target.bat file (right-click/Create Shortcut). Drag the shortcut file onto your Desktop.
|
||||
|
||||
3. To set the preferences simply double-click on your just created short-cut.
|
||||
|
||||
If you already have a correct version of Python and PyCrypto installed and in your path, you are ready to go!

Installing Python on Windows
|
||||
----------------------------
|
||||
I strongly recommend installing ActiveState’s Active Python, Community Edition for Windows (x86) 32 bits. This is a free, full version of the Python. It comes with some important additional modules that are not included in the bare-bones version from www.python.org unless you choose to install everything.

|
||||
|
||||
1. Download ActivePython 2.7.1 for Windows (x86) (or later 2.7 version for Windows (x86) ) from http://www.activestate.com/activepython/downloads. Do not download the ActivePython 2.7.1 for Windows (64-bit, x64) verson, even if you are running 64-bit Windows.
|
||||
1. Download ActivePython 2.7.X for Windows (x86) (or later 2.7 version for Windows (x86) ) from http://www.activestate.com/activepython/downloads. Do not download the ActivePython 2.7.X for Windows (64-bit, x64) verson, even if you are running 64-bit Windows.
|
||||
|
||||
2. When it has finished downloading, run the installer. Accept the default options.
|
||||
|
||||
|
||||
Installing PyCrypto on Windows
|
||||
------------------------------
|
||||
PyCrypto is a set of encryption/decryption routines that work with Python. The sources are freely available, and compiled versions are available from several sources. You must install a version that is for 32-bit Windows and Python 2.7. I recommend the installer linked from Michael Foord’s blog.
