一眼抓关键词 OpenSSL，如果是Windows 64 位系统，下载"Win64 OpenSSL"安装程序。
Win32/Win64 OpenSSL Installer for Windows - Shining Light Productions (slproweb.com)
https://slproweb.com/products/Win32OpenSSL.html 直接安装 openssl 安装包是最快捷方便的方法。
Win64 OpenSSL 版本下即可，选文件夹。
Next
"Select Additional Tasks"，让选择OpenSSL的dll拷贝到什么地方。建议，不要拷贝到系统目录下，如果其他软件使用的OpenSSL版本与你安装这个版本不同，可能导致该软件无法使用。（此解释参考自：http://t.csdn.cn/zDOTd）
然后Install
没钱（donation就是要你捐钱），啥都不选
确保环境变量及CMD可访问
openssl version
