以前、「Kindle本をepubに変換したい」でCalibreを使ったDRM解除について解説しましたが、現在最新のKindle for PC version 1.25.1 だとDRM解除ができないっぽいので忘れないうちにφ(.)メモメモK. Update 2: The DeDRM tools linked in here are even more straightforward for use if you legally own an ebook device. My books bought or owned on the Kobo and Amazon ebook stores can be quite trivially processed with the plugins included in the DeDRM packages linked in my original answer, as they rely on the device ID for DRM removal.
This is our download section where you can find whatever tool that we support or offer tutorials for. The download links are available with multiple mirrors located in different servers for each file, and you can find them labeled by either numbers or name of the file hosting service at the right side.
- Select 'DeDRM' under the 'File type plugins' list and click the 'Customize plugin' button. In the 'Customize' window that opens, click the 'eInk Kindle ebooks' button, then click the + button to add your Kindle's serial number.
- This release is for calibre 5.x. It includes the DeDRM and Obok plugins, versions 7.1.0. For calibre 4.23, you must use the 6.8.1 DeDRM plugin, but the included Obok 7.1.0 plugin should work with calibre 4.2.3.
- This release DOES NOT work with calibre 5.0. Stick with calibre 4.23 for now if you need DRM removal. This release adds full support for the new.kinf2018 key files and the nw KFX encryption.
