WEP Key Changer 0.2

WEP Key Changer project, in short WepKC is a client/server application that allows you to protect your ad-hoc (point to point) wireless network when you are unable to use (due to software or hardware limitations) sophisticated protocols like WPA.

The program consists out of two parts:

the wepkcd daemon, which randomly changes the WEP key after a specified amount of time and sends the chosen key, encrypted with AES, to the wepkcc client
the wepkcc client, which receives the key through the encrypted channel and changes the WEP key in the client machine

The server also waits for packets ("pings") from the client, resetting the WEP key to a defined value when the client goes down and stops pinging the server.

If someone tries to use the wireless network without contacting the server, the connection will be dropped repeatedly in order to prevent further annoyance from strangers (please note that this feature, at the moment, works only in *nix systems).

And its very easy to setup and use.
