安装openssl还是很快的，但注意要依实际配置选取相对应的环境配置及运行对应的BAT文件。

Win7 64位为例 ：

1. 从官网下载openssl源码,并解压至C:\openssl目录

        http://www.openssl.org/source/

2. 配置Perl环境

    本机Oracle自带就有Perl，将其加入PATH.

    否则后面的ms/*.bat时，会找不到perl命令

    没有的就装个perl.    

3. 配置cmd窗口编译环境

   已有装Visual Studio 2013

   运行下列命令:

   3.1 cd C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64

   3.2 vcvars64.bat

4. 运行Configure

   cd C:\openssl

   C:\oracle\product\11.2.0\dbhome_1\perl\bin\perl Configure VC-WIN64A

5. 产生编译脚本.mak

C:\openssl\ms\do_win64a.bat

dir C:\openssl\ms\ntdll.mak

6.运行编译

nmake -f C:\openssl\ms\ntdll.mak

编译完成后，所有可执行文件及dll存放在out32dll目录

可用下列命令检查下:

dir C:\openssl\out32dll\openssl.exe
