assume we enter a name with 4 char

then where would point this:

00454F68                   |.  BB 05000000        MOV EBX,5
00454F6D |> 8B45 F4 /MOV EAX,[LOCAL.3] ; kernel32.7C839AD8
00454F70 |. 0FB67418 FF |MOVZX ESI,BYTE PTR DS:[EAX+EBX-1]

(LOCAL.3 = pointer to the name)

in the other loops is same.

if this is a feature, then take my apologize

if it is not a feature, then you should rethink on your

keygenme.

It's a features yes. :D

@Saduff,

Good work, as always! :thumbsup:

@sama:

It always points to null byte.

That's why I ZeroMemory in my keygen.

@DECiPHER:

All loops always run once, so no need for loops at all. :rolleyes:

@saduff

sure there is almost always a way.

@xDECiPHERx

here my keygen src:

var
i:Integer;
Name: array of Byte;
buffer:string;begin
if (Length(Edit1.Text)< 4) or (Length(Edit1.Text)>10) then
Edit2.Text := 'Namelength must be > 3 and < 10'
else
begin
SetLength(Name,11);
for i := 0 to Length(Edit1.Text)-1 do
Name[i]:= Ord(Edit1.text[i+1]); buffer := 'UnderGround' + IntToHex(Name[4]+ $60,4)+IntToHex((Name[6] shl 3)*3,4)+ '-';
buffer := buffer + IntToHex(Name[3]* $70,4)+ IntToHex(Name[5]* $2012,4)+'-' ;
buffer := buffer + IntToHex(Name[5]+ $450,4)+ GetCurrentUserName; Edit2.Text := StrMD5(buffer);
end;
end;
