算法总结：
1、先用硬件序列号生成累加和(sum)
2、用累加和分别计算出注册码的四部份!
公式是：
第一部份：sum+4*sum
第二部份：sum << 3 -sum
第三部份：sum <<2
第四部份：sum * 0x0b
3、中间有几个固定值穿插其中：分别是：“L”、"W"、"J" 和 "tx30"
==============================================================
附：TC 注册机：
main()
{
int i,sn1,sn2,sn3,sn4,sum=0;
unsigned char sn[80];
clrscr();
printf("\n\n\n //// X梦网页特效精灵3.6keygen ////");
printf("\n===============================================");
printf("\n\ Made by -= HONGJIAN =- ");
printf("\n................................................");
printf("\n\n** Please Your code: ");
gets(sn);
for (i=0;sn[i]!='\0';i++)
sum+=sn[i];
sn1=sum*4+sum;
sn2=(sum<<3)-sum;
sn3=sum <<2;
sn4=sum*0xB;
printf("\n Your Serial Number: L%dW%dJ%dtx30%d\n\n",sn1,sn2,sn3,sn4);
