是個分割軟體,具介紹應該比較好用,具體我沒仔細用過,只是為了破解才下的!
我是個新手,進入CRACK的時間才剛好一個月.請高手多多批評,指教.
開工.前面一大堆的準備工作,我不多說了,直接切入正題:

ret
註冊後寫入登錄檔：HKEY_USERS\.DEFAULT\Software\Teddyware\BananaSplitter
"RegName"="(可以隨便填)"
"RegNum"="1288543" <===這個數是註冊器算出來的
演算法總結:假設輸入密碼為S(必須為7位,且全部為數字0-9) 註冊時輸入的NAME根本沒用.
將密碼S的每一位分別換為16進位制數,分別為S1 S2 S3 S4 S5 S6 S7
S1*2+S2+S3*2+S4+S5*2+S6=A
[A-(取十進位制形式A十位上的數)*10]+1=B
B是否等於S7
並且 1000000<S<3000000
註冊器:註冊碼還真不少!
main()
{
int a,b,s1,s2,s3,s4,s5,s6,s7;
long i=1000000;
for(a=0,b=0;i<=3000000;i++)
{
s1=i/1000000;
s2=i/100000%10;
s3=i/10000%100%10;
s4=i/1000%1000%100%10;
s5=i/100%10000%1000%100%10;
s6=i/10%100000%10000%1000%100%10;
s7=i%10;
a=s1*2+s2+s3*2+s4+s5*2+s6;
b=a-a/10*10+1;
if(b==s7)
printf("\t%ld",i);
}
}
如有錯誤請指出，EMAIL:CL517@YEAH.NET
最後謝謝大家能夠聽我哆嗦完!
