Custom GunZ Launcher

Well, I have seen custom GunZ Launchers here, but none of them send a SerialKey, well this is advice to programmers that have in mind creating one, or have one but have no idea how to send it, just take a look inside the GunZ Launcher's HanAuthForClient.dll and I can promise you, It is easy to figure out, I just took a quick look at it, and so I found out that it checks for the process created by its host (GunZLauncher) and it retrieves the Serial-Key from the GunZ Launcher, then the dll proceeds to compare the Serial-Keys from the daughter process, and then proceeds to letting it launch after injecting into it. (That is my theory from what I looked at) I'm not completely sure if I in fact am correct, but take a look, and let's see what we find out!

P.S. Programming basically is Logic that a computer understands.

I don't mind if you tell me I'm wrong, I would actually appreciate it, it's always good to learn more, and if you are wrong, then better knowing the truth than not at all, right?

actually the serial bit is in the Launcher itself, what you were looking at was for the username and pass

Well, that also is what includes inside it, but here it has the method of comparing the two. This GunZ Launcher needs to have that DLL in order for the client to open, if you add a blank dll and replace it with that one, then you will see it wont launch. Take a look inside with Hex Workshop.

Sorry, I'm not a great Progammer, but what is that, and where did you find it?
