Loadrunner进行md5加密方法

news/2024/7/3 1:21:38

本文主要介绍使用Loadrunner进行字符串md5加密的方法。

使用Loadrunner进行md5比较简单,首先是加载md5.h头文件,后使用头文件中的加密函数即可。

1. md5.h头文件内容如下

#ifndef MD5_H
#define MD5_H
#ifdef __alpha
typedef unsigned int uint32;
#else
typedef unsigned long uint32;
#endif
struct MD5Context {uint32 buf[4];uint32 bits[2];unsigned char in[64];
};
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[3] << 8 | buf[2]) << 16 |((unsigned) buf[1] << 8 | buf[0]);*(uint32 *) buf = t;buf += 4;} while (--longs);
}
#endif
void MD5Init(ctx)struct MD5Context *ctx;
{ctx->buf[0] = 0x67452301;ctx->buf[1] = 0xefcdab89;ctx->buf[2] = 0x98badcfe;ctx->buf[3] = 0x10325476;ctx->bits[0] = 0;ctx->bits[1] = 0;
}
void MD5Update(ctx, buf, len) struct MD5Context *ctx; unsigned char *buf; unsigned len;
{uint32 t;t = ctx->bits[0];if ((ctx->bits[0] = t + ((uint32) len << 3)) < t)ctx->bits[1]++;ctx->bits[1] += len >> 29;t = (t >> 3) & 0x3f;if (t) {unsigned char *p = (unsigned char *) ctx->in + t;t = 64 - t;if (len < t) {memcpy(p, buf, len);return;}memcpy(p, buf, t);byteReverse(ctx->in, 16);MD5Transform(ctx->buf, (uint32 *) ctx->in);buf += t;len -= t;}while (len >= 64) {memcpy(ctx->in, buf, 64);byteReverse(ctx->in, 16);MD5Transform(ctx->buf, (uint32 *) ctx->in);buf += 64;len -= 64;}memcpy(ctx->in, buf, len);
}
void MD5Final(digest, ctx)unsigned char digest[16]; struct MD5Context *ctx;
{unsigned count;unsigned char *p;count = (ctx->bits[0] >> 3) & 0x3F;p = ctx->in + count;*p++ = 0x80;count = 64 - 1 - count;if (count < 8) {memset(p, 0, count);byteReverse(ctx->in, 16);MD5Transform(ctx->buf, (uint32 *) ctx->in);memset(ctx->in, 0, 56);} else {memset(p, 0, count - 8);}byteReverse(ctx->in, 14);((uint32 *) ctx->in)[14] = ctx->bits[0];((uint32 *) ctx->in)[15] = ctx->bits[1];MD5Transform(ctx->buf, (uint32 *) ctx->in);byteReverse((unsigned char *) ctx->buf, 4);memcpy(digest, ctx->buf, 16);memset(ctx, 0, sizeof(ctx));
}
#define F1(x, y, z) (z ^ (x & (y ^ z)))
#define F2(x, y, z) F1(z, x, y)
#define F3(x, y, z) (x ^ y ^ z)

}
void GetMd5FromString(const char* s,char* resStr)
{struct MD5Context md5c;unsigned char ss[16];char subStr[3];int i;MD5Init( &md5c );MD5Update( &md5c, s, strlen(s) );MD5Final( ss, &md5c );strcpy(resStr,"");for( i=0; i<16; i++ ){sprintf(subStr, "%02x", ss[i] );itoa(ss[i],subStr,16);if (strlen(subStr)==1) {strcat(resStr,"0");}strcat(resStr,subStr);}strcat(resStr,"\0");
}

 2. Loadrunner测试代码如下

#include "lrs.h"
#include "md5.h"Action()
{char *s="12345abc";
char *dest=(char *) malloc(10*1024);GetMd5FromString(s,dest);
lr_message(dest);return 0;
}

 

运行截图如下:
