Release Notes
This release DOES NOT work with the latest calibre 5.x that requires Python 3 for plugins.
This release adds full support for the new .kinf2018 key files and the new KFX encryption. Many thanks to Apprentice Sakuya for their work on this.
This means that this release now works with version 1.26 and earlier of Kindle for PC and Kindle for Mac. Books which require the later versions of Kindle for PC/Mac will not be able to be decrypted at this time.
A script to remove DRM from B&N PDFs has been included but not integrated into the plugin, nor tested.
Decrypting KFX
Thanks to work by several people, the DeDRM calibre plugin can decrypt KFX format ebooks from Amazon as long as they are downloaded with Kindle for Mac/PC prior to version 1.27.
Install the KFX Input plugin to automatically locate all of the files that make up a KFX format book and gather them into a KFX-ZIP. After the DeDRM plugin removes the DRM, then the KFX Input plugin will package it into a single KFX file.
