从 Kindle Book 帮助中删除 Drm

安装了带有 kindle-unpacking 插件的 calibres。安装了 DeDRM 插件。在调试模式下重新启动 calibres 并发现 DRM 未被删除。我从调试中收到了此反馈。

Linux DeDRM Calibre 插件不会自动检测和生成剥离 DRM 所需的解密密钥。您必须自行添加。

我在 Linux Mint 19.3 上做过这个，但原理应该是一样的。

先决条件

安装 Wine（按照本指南这里）

使用 Wine 安装 Kindle Reader 1.17 并登录你的账户

使用 Wine 安装 Python 2.7 和 pycrypto

  • 下载最新的 Windows X86 MSI这里

  • 从以下位置下载 pycrypto-2.1.0.win32-py2.7.zip这里并解压缩

  • 使用 Wine 安装

     wine msiexec /i python-2.7.16.msi
 wine pycrypto-2.1.0.win32-py2.7.exe

创建 Kindle 解密文件

如果你还没有 DeDRM 插件，请下载这里并将其添加到 Calibre。

  • 解压DeDRM_tools_6.8.0.zip

  • 接下来，解压DeDRM_Plugin.zip

  • 在解压后的文件夹中找到 kindlekey.py。然后，创建 .k4i 文件。

     wine python.exe kindlekey.py

您应该会看到类似“密钥已成功检索到 kindlekey1.k4i”的消息

将 .k4i 文件添加到 Calibre 中的 DeDRM 插件

  • 打开 Calibre -> 偏好设置 -> 插件 -> DeDRM -> 自定义插件 -> Kindle for Mac/PC 电子书

  • 导入刚刚创建的k4i文件

这样，您就能够从通过 Kindle 应用程序下载的 .azw 文件中删除 DRM。
