loadrunner录制脚本时登录密码转md5

在录制用户注册登录脚本时，常常会遇到web程序对用户密码进行加密处理。在很多时候采用的加密方式为MD5.

这时有两种处理方式：

一、所有用户采用同一密码

例如：每个用户名的密码都为e10adc3949ba59abbe56e057f20f883e

该密码即123456

二、用户采用不同的密码，调用md5加密算法进行加密。

1、首先新建一个MD5加密算法的文件：md5.h

新建一个md5.h文件，文件里面具体的算法网上都有下载，具体如下（直接将下面的算法拷贝到md5.h文件中）：

#ifndef MD5_H
#define MD5_H
#ifdef __alpha
typedef unsigned int uint32;
#else
typedef unsigned long uint32;
#endif
struct MD5Context {

unsigned char in[];
};

extern void MD5Update();
extern void MD5Final();
extern void MD5Transform();
typedef struct MD5Context MD5_CTX;
#endif
#ifdef sgi

{
uint32 t;
do {
t = (uint32) ((unsigned) buf[] <<  | buf[]) <<  |((unsigned) buf[] <<  | buf[]);
*(uint32 *) buf = t;
buf += ;
} while (--longs);
}
#endif

ctx->bits[] = ;
}
void MD5Update(ctx, buf, len) struct MD5Context *ctx; unsigned char *buf; unsigned len;
{
uint32 t;
t = ctx->bits[];
if ((ctx->bits[] = t + ((uint32) len << )) < t)
ctx->bits[]++;
ctx->bits[] += len >> ;
t = (t >> ) & 0x3f;
if (t) {
unsigned char *p = (unsigned char *) ctx->in + t;
t =  - t;
if (len < t) {
memcpy(p, buf, len);
return;
}
memcpy(p, buf, t);
byteReverse(ctx->in, );
MD5Transform(ctx->buf, (uint32 *) ctx->in);
buf += t;
len -= t;
}
while (len >= ) {
memcpy(ctx->in, buf, );
byteReverse(ctx->in, );
MD5Transform(ctx->buf, (uint32 *) ctx->in);
buf += ;
len -= ;
}
memcpy(ctx->in, buf, len);
}
void MD5Final(digest, ctx)
unsigned char digest[]; struct MD5Context *ctx;
{
unsigned count;
unsigned char *p;
count = (ctx->bits[] >> ) & 0x3F;
p = ctx->in + count;
*p++ = 0x80;
count =  -  - count;
if (count < ) {
memset(p, , count);
byteReverse(ctx->in, );
MD5Transform(ctx->buf, (uint32 *) ctx->in);
memset(ctx->in, , );
} else {
memset(p, , count - );
}
byteReverse(ctx->in, );
((uint32 *) ctx->in)[] = ctx->bits[];
((uint32 *) ctx->in)[] = ctx->bits[];
MD5Transform(ctx->buf, (uint32 *) ctx->in);
byteReverse((unsigned char *) ctx->buf, );
memcpy(digest, ctx->buf, );
memset(ctx, , sizeof(ctx));
}

char* CMd5(const char* s)
{
struct MD5Context md5c;
unsigned char ss[];
char subStr[],resStr[];
int i;
MD5Init( &md5c );
MD5Update( &md5c, s, strlen(s) );
MD5Final( ss, &md5c );
strcpy(resStr,"");
for( i=; i<; i++ )
{
sprintf(subStr, "%02x", ss[i] );
itoa(ss[i],subStr,);
if (strlen(subStr)==) {
strcat(resStr,"");
}
strcat(resStr,subStr);
}
strcat(resStr,"\0");
return resStr;
}

2、把新建的md5.h文件，放到脚本中。放置路径为脚本存放路径。例如我的脚本login被存放在E:\LR\JTlogin下面。所以我的放置路径为：E:\LR\JTlogin\login\ (注意：一定要放置在脚本下面)

3、接下来需要在LR中导入md5.h文件。

导入方法：右键单击globals.h，选择Add Files to Script添加md5.h文件。

    

添加完成后，LR中就有该文件了。如下：

4、然后在头文件globals.h中添加引用#include "md5.h"

5、上述步骤完成后，我们现在可调用CMd5()方法进行加密。

就这样我们就加密完成了，最后要做的就是将加密的password值传给需要用到的地方就可以了。
