-separated numbers.  The security system at the moment makes no guarantees

 Have a look at the Security class in security.py for details;
 basically, if the key file contains (x, y), then the security server
-class chooses a random number z (the challenge) in the range 10..100000
-and the client must be able to produce pow(z, x, y) (i.e. z**x mod y).
