Adobe Adept ePub and PDF, .epub, .pdf
|
||||
|
||||
The wonderful I♥CABBAGES has produced scripts that will remove the DRM from ePubs and PDFs encryped with Adobe’s DRM. Installing these scripts is a little more complex that the Mobipocket and eReader decryption tools, as they require installation of the PyCrypto package for Windows Boxes. For Mac OS X and Linux boxes, these scripts use the already installed OpenSSL libcrypto so there is no additional requirements for these platforms.
|
||||
This directory includes modified versions of the I♥CABBAGES Adobe Adept inept scripts for epubs. These scripts have been modified to work with OpenSSL on Windows as well as Linux and Mac OS X. His original scripts can be found in the clearly labelled folder. If a Windows User has OpenSSL installed, these scripts will make use of it in place of PyCrypto.

The wonderful I♥CABBAGES has produced scripts that will remove the DRM from ePubs and PDFs encryped with Adobe’s DRM. These scripts require installation of the PyCrypto python package *or* the OpenSSL library on Windows. For Mac OS X and Linux boxes, these scripts use the already installed OpenSSL libcrypto so there is no additional requirements for these platforms.

|
||||
|
||||
There are two scripts:
|
||||
|
||||
The first is called ineptkey_v5.pyw. Simply double-click to launch it and it will create a key file that is needed later to actually remove the DRM. This script need only be run once unless you change your ADE account information.
|
||||
|
||||
The second is called in ineptepub_v5.pyw. Simply double-click to launch it. It will ask for your previously generated key file and the path to the book you want to remove the DRM from.
|
||||
The first is called ineptkey_v5.1.pyw. Simply double-click to launch it and it will create a key file that is needed later to actually remove the DRM. This script need only be run once unless you change your ADE account information.
|
||||
|
||||
The second is called in ineptepub_v5.3.pyw. Simply double-click to launch it. It will ask for your previously generated key file and the path to the book you want to remove the DRM from.
|
||||
|
||||
Both of these scripts are gui python programs. Python 2.X (32 bit) is already installed in Mac OSX. We recommend ActiveState's Active Python Version 2.X (32 bit) for Windows users.

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.

Ignoble Epub DeDRM - ignobleepub_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 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... click on the Plugins button. Use the file
|
||||
dialog button to select the plugin's zip file (ignobleepub_vXX_plugin.zip) and
|
||||
click the 'Add' button. you're done.
|
||||
|
||||
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 <3 Cabbages scripts on your particular machine.
|
||||
|
||||
** NOTE ** 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 then 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.
|
||||
|
||||
Installation:
|
||||
|
||||
Go to Calibre's Preferences page... click on the Plugins button. Use the file
|
||||
dialog button to select the plugin's zip file (ineptepub_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 Epub DeDRM plugin.
|
||||
|
||||
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.

# This is a python script. You need a Python interpreter to run it.
|
||||
# For example, ActiveState Python, which exists for windows.
|
||||
#
|
||||
# It can run standalone to convert files, or it can be installed as a
|
||||
# plugin for Calibre (http://calibre-ebook.com/about) so that
|
||||
# importing files with DRM 'Just Works'.
|

#
|
||||
# To create a Calibre plugin, rename this file so that the filename
|

# ends in '_plugin.py', put it into a ZIP file and import that Calibre
|

# using its plugin configuration GUI.
|

#
|
||||
# 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 confusin 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.

Changes in version 2.0
|
||||
|
||||
- gensvg.py now accepts two options
|
||||
-x : output browseable XHTML+SVG pages (default)
|
||||
-r : output raw SVG images (useful for later conversion to pdf)
|
||||
|
||||
- flatxml2html.py now understands page.groups of type graphic
|
||||
and handles vertical regions as svg images
|
||||
|
||||
- genhtml.py now accepts an option
|
||||
--fixed-image : which will force the conversion
|
||||
of all fixed regions to svg images
|
||||
|
||||
- minor bug fixes and html conversion improvements
|
||||
|
||||
|
||||
Changes in version 1.8
|
||||
- gensvg.py now builds wonderful xhtml pages with embedded svg
|
||||
that can be easily paged through as if reading a book!
|
||||
(tested in Safari for Mac and Win and Firefox)
|
||||
(requires javascript to be enabled)
|
||||
- genhtml.py now REQUIRES that gensvg.py be run FIRST
|
||||
this allows create of images on the fly from glyphs
|
||||
- genhtml.py now automatically makes tables of words into svg
|
||||
based images and will handle glyph based ornate first
|
||||
letters of words
|
||||
- cmbtc_dump_mac_linux.py has been renamed to be
|
||||
cmbtc_dump_nonK4PC.py to make it clearer
|
||||
when it needs to be used
|
||||
|
||||
|
||||
Changes in version 1.7
|
||||
- gensvg.py has been improved so that the glyphs render exactly (ClarkNova)
|
||||
- gensvg.py has fixed a render order "bug" that allowed some images to cover or hide text. (ClarkNova)
|
||||
- change generated html to use external stylesheet via a link to "style.css"
|
||||
- add missing <title> tag
|
||||
- make xhtml compliant doctype and minor changes to write correct xhtml
|
||||
- make divs that act as anchors be hidden visually and to take up 0 height and 0 width to prevent any impact on layout
|
||||
|
||||
Changes in version 1.6
|
||||
- support for books whose paragraphs have no styles
|
||||
- support to run cmbtc_dump on Linux and Mac OSX provided you know your PID of your ipod or standalone Kindle
|
||||
(contributed by DiapDealer)
|
||||
|
||||
Changes in version 1.5
|
||||
- completely reworked generation of styles to use actual page heights and widths
|
||||
- added new script getpagedim.py to support the above
|
||||
- style names with underscores in them are now properly paired with their base class
|
||||
- fixed hanging indents that did not ever set a left margin
|
||||
- added support for a number of not previously known region types
|
||||
- added support for a previously unknown snippet - <empty></empty>
|
||||
- corrected a bug that caused unknown regions to abort the program
|
||||
- added code to make the handling of unknown regions better in general
|
||||
- corrected a bug that caused the last link on a page to be missing (if it was the last thing on the page)
|
||||
|
||||
Changes in version 1.3
|
||||
- font generation by gensvg.py is now greatly improved with support for contour points added
|
||||
- support for more region types
|
||||
- support for inline images in paragraphs or text fields (ie. initial graphics for the first letter of a word)
|
||||
- greatly improved dtd information used for the xml to prevent parsing mistakes
|
||||
|
||||

ePub_Fixer
|
||||
|
||||
ePubs are specially crafted zip archives. Unfortunately, many of te DRM encoded Adobe Adept and Barnes & Noble ePubs are not "proper" zip archives in that the names of some files in the zip central directory do NOT match the local name given in archive itself. This type of zip archive is technically incorrect/corrupted and can not be read by many other programs.
|
||||
|
||||
ePub_Fixer was designed to fix improperly created zip archives of this type.
|
||||
|
||||
1. Simply double-click to launch ePub_Fixer.pyw.
|
||||
|
||||
2. use the first "..." button to select the ePub (with DRM) that needs to be fixed
|
||||
|
||||
3. use the second "..." button to select where you want the fixed ePub (still with DRM!) to be placed.
|
||||
|
||||
4. Hit the start button.
|
||||
|
||||
Once the program has successfully completed, you can now feed the fixed ePubs into other programs such as DRM removal programs like ignobleepub.pyw and ineptepub.pyw.

# All credit given to The Dark Reverser for the original standalone script.

# I had the much easier job of converting it to Calibre a 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) and click the
|
||||
# "Customize Plugin" button on Calibre's Preferences->Plugins page.
|
||||
# Enter your name and the last 8 digits of the credit card number separated by

# a comma: Your Name,12341234
|
