No Longer Maintained

I have not had the time to devote to this project in recent years that I would have liked. I am delighted to find that someone else has taken on the task of keeping the tools updated, and making releases. I shall be using noDRM's version of the tools from now on.

DeDRM tools for ebooks

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. (Except for the Requiem tools for Apple's iBooks, and Convert LIT for Microsoft's .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.

The individual scripts are now released as two plugins for calibre: DeDRM and Obok. The DeDRM plugin handles books that use Amazon DRM, Adobe Digital Editions DRM (version 1), Barnes & Noble DRM, and some historical formats. The Obok plugin handles Kobo DRM.

Users with calibre 5.x or later should use release 7.2.0 or later of the tools. Users with calibe 4.x or earlier should use release 6.8.x of the tools.

For the latest Amazon KFX format, users of the calibre plugin should also install the KFX Input plugin from the standard calibre plugin menu. It's also available from the MobileRead thread here: https://www.mobileread.com/forums/showthread.php?t=291290

Note that Amazon changes the DRM for KFX files frequently. What works for KFX today might not work tomorrow.

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.

I urge people to read the FAQs. 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. Do remember to unzip the downloaded archive to get the plugin (beta versions may be just the plugin don't unzip that). You can't load the whole tools archive into calibre.

My special thanks to all those developers who have done the hard work of reverse engineering to provide the initial tools.

Apprentice Harper.

这是什么？DeDRM_tools 是一组脚本和 calibre 插件的合集，用于去除电子书的 DRM 保护，以便自由阅读、转换或备份。
这是独立程序还是 calibre 插件？它并不是独立程序，而是打包成两个独立插件 DeDRM 和 Obok，在 calibre 电子书管理器内运行。
我需要先安装 calibre 吗？要用哪个版本？需要。由于这些是 calibre 插件，必须先安装 calibre。calibre 5.x 及以上版本请使用 tools 7.2.0 或更高版本；如果仍在使用 calibre 4.x 或更早版本，请使用 6.8.x 版本。
这个项目还在持续维护吗？已不再维护。原作者已停止相关工作，现在建议用户关注 noDRM 的分支以获取持续更新。另外，亚马逊的 KFX DRM 经常变化，因此对它的支持可能会在没有任何预警的情况下失效。
它能在 Windows、Mac 和 Linux 上使用吗？可以。由于它在 calibre 内运行，而 calibre 本身是跨平台的，只要 calibre 能运行的操作系统，这些插件都能使用。
DeDRM 和 Obok 插件有什么区别？DeDRM 处理亚马逊 DRM、Adobe Digital Editions（版本 1）DRM、Barnes and Noble DRM 以及一些历史格式；Obok 则专门用于去除 Kobo 的 DRM。
处理 Kindle 的 KFX 格式还需要额外安装什么吗？需要。对于最新的亚马逊 KFX 电子书，还需要从 calibre 的标准插件菜单中安装单独的 KFX Input 插件。
要让 Adobe DRM 解除功能持续可用，有什么诀窍吗？请使用 Adobe Digital Editions（ADE）2.0.1 版本。更新的 ADE 版本引入了这些工具无法处理的 DRM 方案。
原作者为什么停止更新这个仓库？他表示自己已没有足够的时间投入到这个项目中，很高兴 noDRM 接手了工具的更新和发布新版本的工作。
