I have already installed the VS C++ Redistributables and OpenSSL but I have no idea on how to tell Qt to link against openSSL dynamically. I'm using the LGPL version of the Qt binaries and Qt Creator all on Windows 7 (the Linux build works just fine)
我已经安装了 VS C++ Redistributables 和 OpenSSL，但我不知道如何告诉 Qt 动态链接 openSSL。我在 Windows 7 上使用 Qt 二进制文件和 Qt Creator 的 LGPL 版本（Linux 构建工作正常）

For some reason Qt wasn't dealing very well with the dlls downloaded from Win32 OpenSSL Installation Project. As I had observed that the application ran smoothly on machines with Tortoise Svn installed I just copied the dlls provided with Tortoise and this worked very well for me.
出于某种原因，Qt 不能很好地处理从 Win32 OpenSSL 安装项目下载的 dll。正如我所观察到的应用程序在安装了 Tortoise Svn 的机器上运行流畅，我只是复制了 Tortoise 提供的 dll，这对我来说非常有效。
I know, it's weird that those dlls worked and those from the Win32 OpenSSL Installation Project didn't but for now copying the dlls from the Tortoise Svn installation folder solved my issue.
我知道，奇怪的是这些 dll 可以工作，而 Win32 OpenSSL 安装项目中的那些 dll 没有，但是现在从 Tortoise Svn 安装文件夹中复制 dll 解决了我的问题。

Download the the latest OpenSSL pre-build binaries from this website.
从此网站下载最新的 OpenSSL 预构建二进制文件。
I used Win32 OpenSSL v0.9.8r Lightas there is some debate about the v1 release. [Client tools are fine you don't need the full distribution]
我使用了Win32 OpenSSL v0.9.8r Light，因为关于 v1 版本存在一些争论。[客户端工具很好，你不需要完整的发行版]
Make sure that you install the dlls so that they are visible in the windows path. Either;
确保您安装了 dll，以便它们在 Windows 路径中可见。任何一个;
- the windows / system32 directory
- the application directory
- or add the location of the dlls to the path enviroment variable
- windows/system32目录
- 应用程序目录
- 或者将dll的位置添加到路径环境变量中
This works for me with Qt v4.6.2
这适用于 Qt v4.6.2
