Reading binary data

Hi guys,
Please help me to read the attached binary file "exactly" to some other file.
The copied file has to be same.
Here is the code that I use. But the copied file is modified.

Code:

---

QString message;
QFile f ( "m1_enc.ct" );
if ( f.open (IO_ReadOnly) )
{
	// file opened successfully
	QDataStream t ( &f );
	// read the contents of the file into message
	char* m = new char[f.size() +1];
	t.readRawBytes ( m, f.size() );
	message = m;
	f.close();
}

---

Code:

---

QFile f ( "copied_file_enc.ct" );
	if ( f.open (IO_WriteOnly) )
		{
		// file opened successfully
		QDataStream t ( &f );
		// read the contents of the file into message
		t << message;
		}
	f.close();

---

In my case the copied_file_enc.ct is modified.

Code:

---

QFile f("input");
f.open(QFile::ReadOnly);
 
QFile f2("ouptut");
f2.open(QFile::WriteOnly|QFile::Truncate);
 
QByteArray dat = f.readAll();
f2.write(dat);
f.close();
f2.close();
