I was bored so I made a pretty easy KeyGenMe. Find the serial and make a Keygen, or just explain the algorithm.

Figured something was wrong with it when I downloaded it lol...
Anyway, the generation for the key is:
| Code: | 00401215 > /0FBE1431 MOVSX EDX,BYTE PTR DS:[ECX+ESI]
00401219 . |B8 79787878 MOV EAX,78787879
0040121E . |F7EA IMUL EDX
00401220 . |C1FA 03 SAR EDX,3
00401223 . |8BC2 MOV EAX,EDX
00401225 . |C1E8 1F SHR EAX,1F
00401228 . |03C2 ADD EAX,EDX
0040122A . |880431 MOV BYTE PTR DS:[ECX+ESI],AL
0040122D . |41 INC ECX
0040122E . |3BCF CMP ECX,EDI
00401230 .^\7C E3 JL SHORT KeyGenMe.00401215 |
Just use the same code to do the keygen:
| Code: |
char tszName[] = _T("Wiccaan");
char tszPass[] = _T("");
int iLength = 0;
iLength = _tcslen( tszName );
_asm
{
mov ecx, 0
mov edi, iLength
CharLoop:
movsx edx, byte ptr ds:[tszName+ecx]
mov eax, 0x78787879
imul edx
sar edx, 3
mov eax, edx
shr eax, 0x1f
add eax, edx
mov byte ptr ds:[tszPass+ecx], al
inc ecx
cmp ecx, edi
jl CharLoop
mov byte ptr ds:[tszPass+ecx], 0 // Null Char To Terminate String
} |

Pardon me, but if I'm correct I took the inputted name and changed it into the correct serial. So of course I would compare that to what you inputted as a serial. Excuse me if I'm wrong.

Oh right xD. I forgot to dereference my pointers. Ok, I re-upped the file. But still no one has actually given a serial.

Do you even bother to test your work before uploading...?
And I posted the algo and code above to make keys:
The key probably wont work if you copypaste here cause the characters are not standard. Next time you make something like this, use characters people can actually type..
Name: Wiccaan
Serial:
