XorRanger Posted January 22, 2014 Share Posted January 22, 2014 (edited) Hello All, This is My Second KeygenMe in Delphi Solution: Only Keygens Are Allowed. A Tutorial Would Be An Added Bonus. Language: Delphi Packer: UPX. Simply Use "upx -d " to Decompress Level: You Decide. Please Solve.

sama Posted January 23, 2014 Share Posted January 23, 2014 (edited) this was very difficult for me, thanks for challenge. XorString db 'THERMODYNAMICS',0 .code Gen proc uses edi esi ebx hWnd:HWND local dwLen: DWORD local lpRes[64]: BYTE invoke GetDlgItemText,hWnd,IDC_NAME,addr szName,SizeOf szName .if eax mov dwLen,eax lea esi, szName xor ecx,ecx .while byte ptr[esi] != 0 xor eax,eax lodsb xor al, byte ptr[XorString][ecx] push ecx invoke wsprintf,addr lpRes,CTEXT("%d"),eax invoke lstrcat,addr szKey,addr lpRes pop ecx inc ecx .if ecx > 0Dh xor ecx,ecx .endif .endw invoke lstrlen,addr szKey invoke CRC16,0, addr szKey, eax invoke wsprintf,addr lpRes,CTEXT("-%X"), eax invoke lstrcat,addr szKey,addr lpRes .else invoke SetDlgItemText,hWnd,IDC_KEY,CTEXT("Name! ?") ret .endif invoke SetDlgItemText,hWnd,IDC_KEY, addr szKey Ret Gen endp may be, i did code it the way you thought as in your code is a bug, e.g. if the name is > then the xorstring the next xoring value is taken from nirvana !but i could be wrong.

XorRanger Posted January 23, 2014 Author Share Posted January 23, 2014 @DimitarSerg, Nice Try But The Challenge Was a KeygenME, So a Keygen is The Only Valid Solution. Link to comment Share on other sites More sharing options...

XorRanger Posted January 23, 2014 Author Share Posted January 23, 2014 @sama, Good Job. It Was Not A Bug, It Was Intentional. Here is The Snippet Constant := 'THERMODYNAMICS'; if I < Length(Constant) then begin TempXor := Ord(Name) Xor Ord(Constant); TempXorString := TempXorString + IntToStr(TempXor); end else begin TempXor := Ord(Name) Xor Ord(Constant[Length(Name) - Length(Constant)]); TempXorString := TempXorString + IntToStr(TempXor); end; 1 Link to comment Share on other sites More sharing options...
sama Posted January 23, 2014 Share Posted January 23, 2014 (edited) not need snippet lets say name is 29 charsconstant is 14 chars so now 29 -14 == 15 (hope i calculate right) according to your code now char name[15] is xored with char at constant[15]but there is nothing except garbage (in this example would be a 00 due the fact that string is zero ended. anyway, as said before, i could be wrong, maybe a specialist like Chooki(we all know of his capabilities) would enlight us.

XorRanger Posted January 23, 2014 Author Share Posted January 23, 2014 @sama, It seems You are right. Thanks For Figuring it Out. Link to comment Share on other sites More sharing options...
ChOoKi Posted January 23, 2014 Share Posted January 23, 2014 It wasn't a big issue, that's why my solution had already taken care of it by: 1) Limiting NameBox to 28 characters. 2) showing message 'Name length should be 1~28' 2 Link to comment Share on other sites More sharing options...
sama Posted January 23, 2014 Share Posted January 23, 2014 thanks Chooki, now i know why i used this line if uMsg == WM_INITDIALOG invoke GetDlgItem,hWnd, IDC_NAME invoke SendMessage,eax,EM_LIMITTEXT,28,0 Link to comment Share on other sites More sharing options...
