Hej!
Inget mrkvrdigt med detta inlgg, men fortfarande en kul grej.
Jag jobbbade p ett "crack-me" program och valde att skapa en junkcode generator fr att komplicera det lite fr gonen.

Planerar att slppa programmet nr jag r helt klar.

Varfr r mitt program unikt? Varfr inte anvnda ngot som redan finns?
Mitt program anvnder sig av olika mnster inom programmering fr att frvirra "decompilers" och producera komplicerad output fr sdanna.

Exempel
Kod: 
int __cdecl main(int _Argc,char **_Argv,char **_Env)

{
  basic_ostream<char,std::char_traits<char>_> *this;
  int iVar1;
  uchar *unaff_EDI;
  undefined4 *puVar2;
  code *pcVar3;
  
  puVar2 = (undefined4 *)&stack0xfffffffc;
  for (iVar1 = 0; iVar1 != 0; iVar1 = iVar1 + -1) {
    *puVar2 = 0xcccccccc;
    puVar2 = puVar2 + 1;
  }
  __CheckForDebuggerJustMyCode(unaff_EDI);
