[Go] Reference lib Static library in VS2010 VC + + project (for example, OpenSSL)

This article transferred from: http://kb.cnblogs.com/page/94467/

OpenSSL is a security protocol that provides security and data integrity for network communications, encompassing key cryptographic algorithms, common key and certificate encapsulation management functions, and SSL protocols, and provides a rich range of applications for testing or other purposes.

First download the OpenSSL package: (http://www.openssl.org/), this is a C language library package, under Windows can be makebuild through Perl to the class library, generating Libeay32, Ssleay32 Lib and DLL files, see: http://blogger.org.cn/blog/more.asp?name=OpenSSL&id=18972, compile to produce such a series of files:

Inc32 inside the C language header file.

1. Now I want to use it in VS2010 project, first I want to create a VC + +. NET project, I have created an MFC application here:

In the project name, click "Right", select "Properties", from the inside to find "VC + + Directory":

Two directory options found:

The directory that contains the directory pointing to your OpenSSL's header file, which points to your LIB, the directory where the DLL resides.

From here, create a new directory to point to the boot directory:

Then switch to "linker", "input":

In additional dependencies, add two lib files:

This completes the reference to the static library.

2. Now look at how to reference it in the project (take the SHA256 algorithm as an example):

#include <openssl/sha.h>

Methods Show:

?

1234567891011121314

// SHA256算法字符串加密void sha256(char* string, char outputBuffer[64]){    unsigned char hash[SHA256_DIGEST_LENGTH];    SHA256_CTX sha256;    SHA256_Init(&sha256);    SHA256_Update(&sha256, string, strlen(string));    SHA256_Final(hash, &sha256);    int i = 0;    for(i = 0; i < SHA256_DIGEST_LENGTH; i++)    {        sprintf(outputBuffer + (i * 2), "%02x", hash[i]);    }}

Call:

?

12	staticunsigned charbuffer[64];sha256(signature, (char*)buffer);

Since the OpenSSL package needs to be compiled using Perl to form Lib and DLL files, I enclose the files that have been made so that they can be used easily!
