Important Security Note – This is not a good method to secure sensitive data. If you want to keep the data away from the reach of your kid, then this can be a good method but it does not provide any security against people with good knowledge of programming. So if you actually want to be sure that no one can ever access the data that you lock, then please use some good software for the purpose.
