<![CDATA[Verschlüsselung was mache ich falsch]]>Hallo,
was ist an diesem Code falsch?

void __fastcall TForm1::endecrypt(char *instr, char *outstr, int isize)
{
   int i;
   for(i = 0; i < isize; i++)
   {
      outstr[i] = instr[i] ^ i;
   }
   outstr[isize] = NULL;
}
// in Button Click
AnsiString test;
test = "Hallo du";
char *in = new char[sizeof(test) + 1];
char *out = new char[sizeof(test) + 1];

strcpy(in , test.c_str());
endecrypt(in, out, sizeof(in));

Label1->Caption = out;

delete [] in;
delete [] out;

Also, dieser Code spuckt mir immer nur 4 Stellen aus, was kann daran falsch sein???

Gruß

Und nachgelesen, was die Funktion genau macht?

statt sizeof habe ich jetzt test.length() genommen und jetzt geht es, Danke!.
