using OpenSSL in Visual Studio 2012
提问by rdanee
I have downloaded the latest release version of Openssl from http://www.openssl.org/source/
我已经从http://www.openssl.org/source/下载了最新版本的 Openssl
I would like to use it in Visual Studio 2012, especially getting the md5/sha-1 hash of a file, but I can not include / setup the environment with the openssl library. To be honest I got confused what to include, and where, however I have read the README-s.
我想在 Visual Studio 2012 中使用它，尤其是获取文件的 md5/sha-1 哈希，但我无法使用 openssl 库包含/设置环境。老实说，我很困惑要包含什么以及在哪里，但是我已经阅读了 README-s。
I'm getting this error.
我收到这个错误。
Error 1 error LNK2019: unresolved external symbol _MD5_Init referenced in function _main
So my question is, I have downloaded the latest release (openssl-1.0.1e.tar.gz), what should I config in VS2012 to be able to use the lib? Thanks!
所以我的问题是，我已经下载了最新版本（openssl-1.0.1e.tar.gz），我应该在 VS2012 中配置什么才能使用 lib？谢谢！

The steps required to use the openSSL lib with VS2012:
在 VS2012 中使用 openSSL 库所需的步骤：
- download and install a version (I have 64bit OS, however I installed 32bit openssl) from http://slproweb.com/products/Win32OpenSSL.html.
- New project in VS, then Configuration Properties/C/C++/General/Additional Include Directories: openssl include folder (C:\OpenSSL-Win32\include)
- Linker/General/Additional Library Directiories: C:\OpenSSL-Win32\lib
- Linker/Input/Additional Dependencies :
- 从http://slproweb.com/products/Win32OpenSSL.html下载并安装一个版本（我有 64 位操作系统，但是我安装了 32 位 openssl）。
- VS中新建工程，然后配置属性/C/C++/General/Additional Include Directories: openssl include folder (C:\OpenSSL-Win32\include)
- 链接器/通用/附加库目录：C:\OpenSSL-Win32\lib
- 链接器/输入/附加依赖项：
libeay32.lib libeay32MTd.lib libeay32MT.lib libeay32MDd.lib libeay32MD.lib ssleay32.lib ssleay32MTd.lib ssleay32MT.lib ssleay32MDd.lib ssleay32MD.lib
libeay32.lib libeay32MTd.lib libeay32MT.lib libeay32MDd.lib libeay32MD.lib ssleay32.lib ssleay32MTd.lib ssleay32MT.lib ssleay32MDd.lib ssleay32MD.lib
(It was written that I need to only add that one which matches with C/C++/Code Generation/Runtime Library, but It works me this way.)
（有人写道，我只需要添加与 C/C++/代码生成/运行时库匹配的那个，但它以这种方式工作。）
- Copy theese files into current VS folder /VC/lib
- 将这些文件复制到当前 VS 文件夹 /VC/lib

What compiler did you use to compile OpenSSL? Did you use MinGW? If so, make sure you don't strip them (or just with --strip-unneeded) otherwise import symbols will be stripped. Do the header and lib version match?
你用什么编译器来编译 OpenSSL？你用过MinGW吗？如果是这样，请确保不要剥离它们（或仅使用 --strip-unneeded），否则导入符号将被剥离。标头和 lib 版本是否匹配？
Maybe you want to try pre built ones from: http://slproweb.com/products/Win32OpenSSL.htmlthose work for sure.
也许您想从以下网址尝试预先构建的：http: //slproweb.com/products/Win32OpenSSL.html那些肯定有效。
