Does somebody have a peace of code which decode the encode packets sent by the Quake III client?

the in-game packets of quake3 use a particular compression and encryption (you can take a look at the ioquake3 source code) and, as far as I know, still don't exist proxy-like tools for showing the clear content of such packets in real-time.

but does ioquake3 retrive not encrypted data or does this encriptyon remains not public ?

uhmmm I have not understood.
the encryption algorihtm is public since the quake 3 source code is public under GPL.

the algorithm allows to decrypt the packets only if you are monitoring the packets from the beginning of the connection because the key changes after almost each packet (the key is nothing else than the previous received command or something similar)
