You can't load the whole tools archive into calibre. But to cover the most common: Do remember to unzip the downloaded archive to get the plugin (beta versions may be just the plugin don't unzip that). 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.

If you encounter issues with this plugin in Calibre 4.x or lower, please open a bug report. The v10.0.0 versions of this plugin should both work with Calibre 5.x (Python 3) as well as Calibre 4.x and lower (Python 2). This plugin will start with version v10.0.0 so there won't be conflicting / duplicate version numbers when Apprentice Harper's version is updated again. Take a look at the CHANGELOG to see a list of changes since the last version by Apprentice Harper (v7.2.1). I've added some of the PRs that still haven't been merged, as well as added some more features / bugfixes myself. This is a fork of Apprentice Harper's version of the DeDRM tools.
