[C语言]给账号密码进行MD5加密

源码解析

//md5加密用户密码
UtlMd5_t ctx;
unsigned char serverDigest[16];
utl_md5_init(&ctx);
//md5初始化
utl_md5_update(&ctx, "admin", strlen("admin"));
//将要加密的信息传递给初始化过的MD5结构体，无返回值
//穿账号
utl_md5_update(&ctx, "debug_get_vs_status", strlen("debug_get_vs_status"));
//传控制指令
utl_md5_update(&ctx, "admin123", strlen("admin123"));
//传密码
utl_md5_final(&ctx, serverDigest);
//转换成32位的16进制字符串
int i=0;
unsigned char decrypt32[64]={
    0};
char temp[8]={
    0};

for(i=0;i<16;i++)
{
    
	sprintf(temp,"%02x",serverDigest[i]);//把十六进制转换成字符串%x=0x6b ==> %s="6b"
	strcat((char *)decrypt32,temp);
}
//最后生成的decrypt32即为md5加密密码："6be7c69c5cdf177753270cf390ef1e90"


//成功发送
