How to use SimlpeCrypt in qt c++

TheCeylann

I save my password in a text file. I need to save the string by encrypting it during recording. I think I can solve this with SimpleCrypt, but since I started c++ a few days ago, I couldn't use simplecrypt. Can you teach me how to do this?

void SecondWindow::on_pushButton_8_clicked()
{
    QFile file(passLocation + "/test/password.txt");
    QFile tmpFile(passLocation + "/test/passwordtemp.txt");


     if (!file.open(QIODevice::ReadOnly | QIODevice::Text) || !tmpFile.open(QIODevice::WriteOnly | QIODevice::Text))
         return;

     QTextStream  in(&file);

     QString line = in.readLine();
     qDebug()<< line;


     if (line == ui->oldPassBox->text() && ui->confirmPass->text() == ui->newPassBox->text())
     {

        
         QTextStream  tmp(&tmpFile);
         tmp << ui->newPassBox->text();
         
         

     } else
     { 
         QMessageBox::warning(this, "error","Error" );
         QTextStream  tmp(&tmpFile);
         tmp << line     ;

     }



 
     file.close();
     tmpFile.close();
     QFile::remove(passLocation + "/test/password.txt");
     QFile::rename(passLocation + "/test/passwordtemp.txt",  passLocation + "/test/password.txt" );

    }

I referenced this link for SimpleCrypt [SımpleCrypt]https://wiki.qt.io/Simple_encryption_with_SimpleCrypt) And examples from this link examples
