Download the english version from www.openssl.org. I haven't had much luck in contacting their website, so I also put it on our server here. INSTALL.W32 contains the instructions for installation under windows. The installation states that you must install perl. You must do this before you can even run the make files. You can download perl from http://www.activestate.com/ActivePerl. After installing perl, you will need to build the make files by running ms\do_ms in the openssl folder. The next step has your run nmake, but make sure you have it in your path (or run it from the directory where it resides), nmake is usually located at C:\Program Files\Microsoft Visual Studio\VC98\Bin. VC++ vars must also be registered for the dos prompt, you can do this by running VCVARS32.BAT. You will need to compile the dlls with nmake. Type nmake -f ms\ntdll.mak. Now you have the dlls and lib files you need for VC++, but all the files are not in the correct place. Two dlls and lib files, libeay32 and ssleay32, must be copied from the out32dll directory. The dlls need to be in the same directory as your exe file, and the lib needs to be in the LIB folder (usually C:\Program Files\Microsoft Visual Studio\VC98\Lib or C:\Program Files\Microsoft Visual Studio.NET 2003\Vc7\Lib if you're using .NET) That's not all though, you must copy the .cpp and .h files to the include folder of VC++ (usually C:\Program Files\Microsoft Visual Studio\VC98\Include or the corresponding path for .NET) The best idea is to put them all in a subfolder in the Include folder. Name the subfolder openssl. An easy way to put them all in the same subfolder is to extract using winzip and don't preserver the file structure, so all files are copied to the openssl directory with no sub directories being created. Now all you have to do is type #include <openssl/whatever.h> and you will get whatever file you need. Also, make sure you include the libraries under link in project setting of VC++.
