I ran Calibre in deBug mode with the following result:īlacklisting the DeDRM plugin as it is too old and causes crashes I keep getting the error message that this book has DRM and can't be opened.

My special thanks to all those developers who have done the hard work of reverse engineering to provide the initial tools.Calibre and DeDRM have suddenly stopped working. You can't load the whole tools archive into calibre. Do remember to unzip the downloaded archive to get the plugin (beta versions may be just the plugin don't unzip that). But to cover the most common: Use ADE 2.0.1 to be sure not to get the new DRM scheme that these tools can't handle. I welcome contributions from others to improve these tools, from expanding the range of books handled, improving key retrieval, to just general bug fixes, speed improvements and UI enhancements. What works for KFX today might not work tomorrow. Note that Amazon changes the DRM for KFX files frequently. It's also available from the MobileRead thread here: Users with calibe 4.x or earlier should use release 6.8.x of the tools.įor the latest Amazon KFX format, users of the calibre plugin should also install the KFX Input plugin from the standard calibre plugin menu. Users with calibre 5.x or later should use release 7.2.0 or later of the tools.

The DeDRM plugin handles books that use Amazon DRM, Adobe Digital Editions DRM (version 1), Barnes & Noble DRM, and some historical formats. The individual scripts are now released as two plugins for calibre: DeDRM and Obok. lit ebooks.) This includes the tools from a time before Apprentice Alf had a blog, and continues through to when Apprentice Harper (with help) took over maintenance of the tools. (Except for the Requiem tools for Apple's iBooks, and Convert LIT for Microsoft's. This is a repository that tracks all the scripts and other tools for removing DRM from ebooks that I could find, committed in date order as best as I could manage. I shall be using noDRM's version of the tools from now on. I am delighted to find that someone else has taken on the task of keeping the tools updated, and making releases. I have not had the time to devote to this project in recent years that I would have liked.
