Small SCAR Challenge.

I recently wrote a cypher encoder/decoder, and wanted to try something.

I will post my algorithm for it, so you can run it through that, then I'll post the output, and your job is to find the four letter code word that deciphers my code properly.

Output that is being looked for:

The first person to post the sentence "Candles are awesome" wins.

Here is a list of four letter words I'll be taking my code word from:

Here is my Decoder, with the string to decode already placed in the "ToDecrypt" constant slot.

Code:

program Cypher_Decrypt;

var
  C1, C2, Return, Decrypted, Decrypting : string;
  I : Integer;

const
  CodeWord = '';
  ToDecrypt = '5+@ B,A?5 3@A?21 52 32?5 5+@ ?@15@1(@ "(R1)/@? RA@ R8@?20@" 8,1?K';

begin
  Return := CodeWord;
  For I := 1 to length(Return) do
  begin
    if length(C1) < 13 then
    begin
      C1 := C1 + strget(Return, I);
    end else
      C2 := C2 + Strget(Return, I);
  end;
  C1 := Uppercase(C1);
  C2 := Uppercase(C2);
  For I := 40 to 94 do
  begin
    If length(C1) < 27 then
    begin
      If Pos(chr(I), C1) = 0 then
        If Pos(chr(I), C2) = 0  then
          C1 := C1 + chr(I);
    end else
        begin
    If length(C2) < 27 then
    begin
      If Pos(chr(I), C1) = 0 then
        If Pos(chr(I), C2) = 0  then
          C2 := C2 + chr(I);
    end;
  end;
  end;
  Decrypting := uppercase(ToDecrypt);
  For I := 1 to length(ToDecrypt) do
  begin
    If Pos(Strget(Decrypting, I), C1) <> 0 then
    begin
      Decrypted := Decrypted + Strget(C2, Pos(Strget(Decrypting, I), C1));
    end else
      begin
      If Pos(Strget(Decrypting, I), C2) <> 0 then
      begin
        Decrypted := Decrypted + Strget(C1, Pos(Strget(Decrypting, I), C2));
      end else
        Decrypted := Decrypted + strget(Decrypting, I);
    end;
  end;
  Cleardebug;
  WriteLn(Decrypted);
end.
