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 {

uint32 buf[];

uint32 bits[];

unsigned char in[];

};

extern void MD5Init();

extern void MD5Update();

extern void MD5Final();

extern void MD5Transform();

typedef struct MD5Context MD5_CTX;

#endif

#ifdef sgi

#define HIGHFIRST

#endif

#ifdef sun

#define HIGHFIRST

#endif

#ifndef HIGHFIRST

#define byteReverse(buf, len) /* Nothing */

#else

void byteReverse(buf, longs)unsigned char *buf; unsigned longs;

{

uint32 t;

do {

t = (uint32) ((unsigned) buf[] <<  | buf[]) <<  |((unsigned) buf[] <<  | buf[]);

*(uint32 *) buf = t;

buf += ;

} while (--longs);

}

#endif

void MD5Init(ctx)struct MD5Context *ctx;

{

ctx->buf[] = 0x67452301;

ctx->buf[] = 0xefcdab89;

ctx->buf[] = 0x98badcfe;

ctx->buf[] = 0x10325476;

ctx->bits[] = ;

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。
