[Help]Rijndael Aes encrypt file

[Naworia]

Hello I'm new in c++ and i had a script that encoding setting files. It says error about Rijndael.h because i have not it yet. But i know it gives error again when i have it. Can you explain me for step by step that what must i do generally for complete this script?

Code :

PHP Code:

#include "stdafx.h"
#include "Rijndael.h"
#include <fstream>
#include <iostream>
using namespace std;


int _tmain(int argc, _TCHAR* argv[])
{
    CRijndael Rij;
    char DecryptStr[16] = {0};
    char DecryptedStr[20] = {0};
    char filestr[999999] = {0};
    Rij.MakeKey("zontim",CRijndael::sm_chain0, 16,16);

    FILE *filein;
    filein = fopen(argv[1],"rb");
    fseek(filein,0,SEEK_END);
    int size = ftell(filein);
    rewind (filein);
    fseek(filein,0,SEEK_SET);
    char *bufin = (char*)malloc(sizeof(char)*size+1);
    memset(bufin,0,sizeof(char)*size);
    fread(bufin,1,size,filein);

    FILE *fileout;
    char outputname[999] = {0};
    sprintf(outputname,"%s.set",argv[1]);
    fileout = fopen(outputname,"a+");

    //für ft
    
    char bla[9999999] = {0};
      for(int i = 0;i < (size);i+=16)
      {
          Rij.Encrypt(bufin+i, filestr,16);
          strcat(bla,filestr);
     }
    for(int i = 0;i < (size);i++)
    {
        bla[i+1] = bla[i];
    }
     bla[0] = 0x0b;
     fwrite(bla,1,(size+1),fileout);
    fclose(filein);
    fclose(fileout);
    free(bufin);
    cout << "fertig";
    cin.get();
    return 0;
}

Hey,
first of all this is very very bad C++. I don't know where you got that from, but this is garbage.
About your problem: Well, you might want to tell us want error you exactly get. If it says Rijndael.h does not exist, then you might want to add it to your project.

I added it and then it says another xxxx.h, how can i get that all Rijndael pack?
