+GS enctype2 servers list decoder/encoder 0.1.2
+by Luigi Auriemma

+
+
+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);
