Obfuscated

A small taste of what I've been doing on my office for over a week

And what the hell is that? Friends, that's an Applet that is going to be installed on a SIM Card. Well, part of it.

My PL gave me an objective to study the structure of an applet bytecode. It was not a pretty sight haha. Anyway, I'm supposed to do a knowledge sharing this year on this topic as well, and the more I try to learn, the more I'm convinced that my audience will go to sleep instantly.

Hope it's not as bad as I think... Or maybe I should study more to find what we can do with these hexes..

Let there be bytecodes!

P.S. This is not a proprietary data, it's only a crappy applet that I used to develop on my training. I'm not stupid enough to post a product hex inside here. Anyway, I'm putting only the common and not-so-important part here >:)
