[Python] NDT files decryptor

[neuronet]

The file encryption is same in ALL ao versions

[sofiantagilo]

how can make a txt file could be NDT ???

[neuronet]

depends on client version.. old versions you just need to rename to .ndt and if will work... new clients like KAO expect them to be encrypted again.

I've tried changing the file extension but failed, it seems need to compile from txt NDT, can you help me??

[neuronet]

it's simple XOR encryption for the 1.1 encryption.

here's some old delphi code i used for encrypting text back to ndt/ntd:

procedure TForm1.Encrypt;
var
  key: Byte;
  c, new_size: integer;
  size: string;
  myfile: file;
  inp_file: string;
  directory: string;
  size_2: integer;
begin
  Memo1.Lines.SaveToFile(ExePath + '3.txt', Tencoding.Unicode);
  inp_file := ExePath + '3.txt';
  // Set Key to 51
  key := $51;
  SetLength(Source, 0);
  // Select file to Crypt
  // Read File
  ReadBytesFromFile(inp_file);
  // Encrypt
  new_size := length(Source);
  for c := new_size - 2 downto 0 do
    Source[c] := (Source[c] xor Source[c + 1]) + key;
  SetLength(Dest, new_size + 24);
  move(Source[0], Dest[24], new_size);
  Dest[$0] := $4E;
  Dest[$1] := $43;
  Dest[$2] := $52;
  Dest[$3] := $00;
  Dest[$4] := $01;
  Dest[$5] := $00;
  Dest[$6] := $01;
  Dest[$7] := $00;
  size := IntToHex(new_size, 8);
  Dest[$8] := strtoint('$' + copy(size, 7, 2));
  Dest[$9] := strtoint('$' + copy(size, 5, 2));
  Dest[$A] := strtoint('$' + copy(size, 3, 2));
  Dest[$B] := strtoint('$' + copy(size, 1, 2));
  Dest[$C] := key;
  Dest[$D] := $00;
  Dest[$E] := $00;
  Dest[$F] := $00;
  Dest[$10] := $00;
  Dest[$11] := $00;
  Dest[$12] := $00;
  Dest[$13] := $00;
  Dest[$14] := $00;
  Dest[$16] := $00;
  Dest[$17] := $00;
  // Write to file
  directory := IniFile.ReadString('Directories', 'File_2', '');
  AssignFile(myfile, directory + Label2.Caption);
  size_2 := length(Dest);
  ReWrite(myfile, size_2);
  BlockWrite(myfile, Dest[0], 1);
  CloseFile(myfile);
end;

if you want can make you tomorrow a small gui program for encryption.

Ok, i want small gui program, I will wait ... tx

how to find the file that contains the string healtpoint NDT in the game atlantica online

[neuronet]

??? what string ???

[sofiantagilo]

String of healthpoint or what the name of file to edit health point in atlantica online

[neuronet]

editing healthpoint? there is no file to edit them... even if you do it with cheatengine it won't help you cause all is serverside

[sofiantagilo]

how to do that can be written on the server side ???

[neuronet]

a) HACK nexon server
b) IF i would know how.. do you think i would tell?

[sofiantagilo]

LOL .. ok tx taht the info .. because the server Game Atlantica Online Indonesia is not a good, my equipt lost after maintenance, so I'm annoyed ....

[neuronet]

1. Server for IndoAO is same as for all other
2. Gear for sure not lost only for ONE person after a maint
3. write a support ticket if you're sure that it's a bug due to maintenance

[sofiantagilo]

Where should I report it?? Costumer Atlantica Online were never respon any complaints from gamer

[neuronet]

i can tell you they answer... i have contact to a GM and FM and i get responses... write a support ticket or make a post in official forum

btw.. here is your encryptor:
