Some of the servers and clients are called RSA; what does that mean?
RSA is a way for servers to make sure that players are not using cyborg clients. The RSA package generates a header file containing a public and a private encryption key. These keys are compiled into the client; the private key encrypts the data and the public key decrypts it. The main advantage of RSA over the old reserved.c method is that the server gods need know only the public key; the RSA package can be kept in a few select hands. Also, if someone breaks the protection on a certain private key, that key can be turned off by the server god, and that specific client will no longer work.
