VC environment to compile OpenSSL (just an example, there are many related articles on the internet)

VC Environment OpenSSL installation and programming process

SSL is secure Sockets Layer and is a secured socket protocol, please refer to the link for details.

Some MAK files need to be generated during configuration, which are generated in Perl scripts, so install a ActivePerl

activeperl:http://www.activestate.com/activeperl/

openss:http://www.openssl.org/(this article uses OPENSSL-1.0.0-BETA5)

Refer to the INSTALL.WIN32 instructions under the OpenSSL directory for installation:

1, enter the decompression directory.

>CD c:/Openssl-1.0.0-beta5

2, running Configure.

>perl Configure Vc-win32

If unsuccessful, there will be obvious hints.

3. Create a Makefile file.

>ms/do_ms

It is recommended to use this method, and the other two methods must be used to ensure that the machine has a compiler to use.

: Ms/do_masm (Default VC comes with the compiler; also download and install it yourself)

: ms/do_nasm (download required)

4, configure the VC environment variable.

>CD C:/Program Files/microsoft Visual studio/vc98/bin

>vcvars32.bat

5, compile the dynamic link library.

>CD c:/openssl-0.9.8k

>nmake-f Ms/ntdll.mak

If the compilation succeeds, the final output is in the Out32dll directory: executable files, two DLLs (Ssleay32.lib, Libeay32.lib), and two lib files (Ssleay32.dll, Libeay32.dll).

6. Add header file and static link library path for VC.

Toolsàoptionsàdirectores, add the C:/OPENSSL-0.9.8K/INC32 directory to the Include files, and add C:/openssl-0.9.8k/out32dl to Libray files L

7, write the OpenSSL program, can refer to C:/openssl-0.9.8k/demos

(1) include the corresponding header file

#include <openssl/***. H >

(2) Add a static link library

#pragma comment (lib, "Libeay32.lib")

#pragma comment (lib, "Ssleay32.lib")

or Projectàsettingsàlinkàobject/library modules fill out libeay32.lib ssleay32.lib.

(3) Copy the dynamic link library Ssleay32.dll, libeay32.dll to the C:/windows/system32 or Debug directory, and ensure that the dynamic link library is in the correct path.
