Since I'm merely a code monkey and not a cryptographer, all that I can do is encrypt a stream and then apply another level of encryption over it by using a different algorithm.

I know you guys don't like this approach, yet I have got no references on how to make it better. All I know is that if the first layer is broke, the would-be attacker will get another jumbled stream and will have to start all over again.

The idea of my question is, can we do that in a proper manner? What proper manner is that, exactly?
