a980e066a01 c5aebcca01 Add support for "hardened" Adobe DRM
What took the most time was not reverse-engineering
the scheme, but actually finding books using it...

DeDRM_plugin.zip
================
This plugin will remove the DRM from:
- Kindle ebooks (files from Kindle for Mac/PC and eInk Kindles).
- Adobe Digital Editions ePubs (including Kobo and Google ePubs downloaded to ADE)
- Adobe Digital Editions PDFs
For limitations and work-arounds, see the FAQ at https://github.com/noDRM/DeDRM_tools/blob/master/FAQs.md (or the FAQ in Apprentice Harper's original repository at https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md)
Installation
------------
Open calibre's Preferences dialog. Click on the "Plugins" button. Next, click on the button, "Load plugin from file". Navigate to the unzipped DeDRM_tools folder, find the file "DeDRM_plugin.zip". Click to select the file and select "Open". Click "Yes" in the "Are you sure?" dialog box. Click the "OK" button in the "Success" dialog box.
Customization
-------------
For Kindle ebooks from an E-Ink based Kindle (e.g. Voyage), or books downloaded from the Amazon web site 'for transfer via USB' to an E-Ink base Kindle, you must enter the Kindle's serial number in the customisation dialog.
When you have finished entering your configuration information, you must click the OK button to save it. If you click the Cancel button, all your changes in all the configuration dialogs will be lost.
Troubleshooting
---------------
If you find that the DeDRM plugin is not working for you (imported ebooks still have DRM - that is, they won't convert or open in the calibre ebook viewer), you should make a log of the import process by deleting the DRMed ebook from calibre and then adding the ebook to calibre when it's running in debug mode. This will generate a lot of helpful debugging info that can be copied into any online help requests. Here's how to do it:
- Remove the DRMed book from calibre.
- Click the Preferences drop-down menu and choose 'Restart in debug mode'.
- Once calibre has re-started, import the problem ebook.
- Now close calibre.
A log will appear that you can copy and paste into a GitHub issue report at https://github.com/noDRM/DeDRM_tools/issues. Please also include information about the eBook file.
