GS enctype2 servers list decoder/encoder 0.1.2
by Luigi Auriemma
e-mail: aluigi@autistici.org

INTRODUCTION
============
This is the algorithm used to decrypt the data sent by the Gamespy
master server (or any other compatible server) using the enctype 2
method.


USAGE
=====
Add the following prototype at the beginning of your code:

  unsigned char *enctype2_decoder(unsigned char *, unsigned char *, int *);

then use:

        pointer = enctype2_decoder(
            gamekey,        // the gamekey
            buffer,         // all the data received from the master server
            &buffer_len);   // the size of the master server

The return value is a pointer to the decrypted zone of buffer and
buffer_len is modified with the size of the decrypted data.

A simpler way to use the function is just using:

  len = enctype2_wrapper(key, data, data_len);
