From the manual :

If I use dplay_encrypt , does this mean that I can move the client localy and send position to server , or I still have to use server authority over client? I mean , is it easy to cheat/hack with encription?

*EDIT* This can save a lot of traffic

Yes. Whatever the manual says, it's bullshit and it doesn't help you in any way to authenticate a client and the data they send. It may help against man in the middle attacks and people sniffing on the wire, although, since the manual makes no effort in telling you how the encryption works and what is used to authenticate and authorise clients, I wouldn't exactly trust the system.

Given Gamestudios track record with encryption, which basically boils down to security-through-obscurity and no one actually caring enough to break it since it's not worth the effort... Well, I don't know, use with care and don't trust a client. Ever.

How should this protect you from manipulating the position of your player in memory? Works even in World of Warcraft because the movement is clientsided. If everything would be client sided nobody would play this game because you could also change your health/mana etc in memory. Would be kind of shitty^^
But you should enable it because this way people have to reverse your game before they can do anything. Sending and faking packets is most of the times easier without any encryption and/or hash/crc check.
If you need an anti-cheat I could also provide one with my gui gwen

Sounds familiar

By the way, I'm not sure what I should think of someone with a leetspeak username and no track record in cryptography (or anything, really), trying to sell an anti-cheat system with a GUI package. Is there a chance to peer-review it?

Edit: Error-whateverthenumberis pointed rightfully out that we don't know yet if you are selling it. But why would you build snakeoil if you don't want to sell it?

I'm offended. There is no dash in my name.

The dash is silent :\

You are silent!


EDIT: Come to think of it, you are not really silent, no.

I know. I'm eating. Didn't your mom teach you manners and told you that you shouldn't talk while eating?

Well, I am not eating. I am just defending myself after you, in obvious malicious intent, misspell my name.

How could you.

Not this again.
