用Calibre导入Kindle电子书并去除DRM保护 – Librehat的部落格

本文的目的绝非为了盗版之用，而是很多美国亚马逊买的Kindle设备（如Kindle 4、Kindle 5）无法在中国亚马逊里注册，不能通过正常的推送渠道购买正版电子书，因此这是一个万不得已的做法，在中国亚马逊买书然后破解再传到美版（或日版）Kindle里。

需要下载的软件有： Calibre 、 DeDRM插件、 Kindle for PC （或者 for Mac ）

Calibre本身是用Qt和Python写成的，因此DeDRM插件也是Python写的。下面以Windows为例（Linux下没有Kindle客户端需要Wine有点麻烦，而Mac和Windows PC大同小异）。

准备电子书

首先安装好Calibre和Kindle for PC，打开Kindle for PC（快捷方式就叫做Kindle），用 中国亚马逊 的账号登录，进去之后简单设置一下吧（比如我改动了 内容文件夹 为 D:\Kindle ）。

然后去 中国亚马逊 上买Kindle电子书，推送到Kindle for PC上（不少人是为了知乎周刊吧……）。刷新一下图书馆，确保电子书下载完毕，这时去 内容文件夹 看看吧，azw文件已经躺在那里了。

安装去除DRM保护的插件

不过这些azw文件是带有DRM保护的，你直接传到Kindle里是打不开的（如果Amazon能解决这个DRM的这个问题也算是一大进步啊），这个时候就需要Calibre和DeDRM插件了。需要说明的是Calibre本身是不支持去除DRM的，官方插件仓库里也没有这个插件。在DeDRM的 releases 里下载最新的zip包，解压，在dedrm-ebook-tools-6.0.4\DeDRM_calibre_plugin下有一个英文说明txt文档，还有一个就是插件包DeDRM_plugin.zip！

打开Calibre，点击首选项（或者快捷键Ctrl+P），点击高级选项下的插件，点击“从文件加载插件”，选择DeDRM_plugin.zip，接下来会有一些安全警告什么的，一路下一步忽视警告。 你可能需要重新启动Calibre使其生效。

把Kindle for PC下载的那些azw文件添加到Calibre即可（直接拖进去吧），DeDRM插件会自动去除azw文件的DRM保护并转换成原始格式（azw3或者mobi、prc等）。神马？不会用Calibre传书到Kindle？连接USB会不会，点击鼠标会不会？

请勿通过此法传播盗版书籍！支持正版，人人有责。

也希望有关部门能放宽文化管制，希望能看到Amazon.cn和Amazon.com账户数据互通的那一天（我的中国梦……>_<#）。
