Sorry

This should still be done in C/C++.

First of all, you would need to inject this code into the target process, which is not possible to do with Lua. Additionally, MicroMacro is designed as a tool to run along-side of the target program and send inputs to it.

Another tool could be created that would allow you to modify the packets in Lua (although the actual program would still be an injected DLL written in C/C++), but still might not be recommended. It would work, but it could also slow things down.

Thats not good then, I'm not that advanced. Is it possible to read incoming packets and decrypt them with lua?

No.
