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.
