Challenge: hack.lu CTF 2011 Spy Aboard! (300)

Last year the FluxFingers organized the hack.lu 2011 CTF. Some weeks ago I read an eMail on the FluxFingers eMail account, that the server with all challenges is down.

I don't know if we find a mirror, where we can set up a VM for all challenges, so I would like to publish my challenge for this CTF here. Notice that this was the first time I wrote a challenge for a CTF and the first time I coded something with python. Therefore, the code isn't such a beauty

Spy aboard!
We have a spy aboard! Around 5 minutes ago we intercepted an encrypted transmission to an enemy outpost. It seems like we interrupted the mole in the act because
we found an open transmission program on our terminals. We are 100% sure that he sent the position of our fleet to the outpost to plan an attack against us. Our position
at the time of the transmission was:

position: Harcon System , Planet Crematoria , x: 129.23432231423 degrees y: 111.13442353423 degrees , z: 100,13142234423 degrees

We need the spies authorization code to prevent this attack. You as our crypto expert you have to find it! The survival of 10000 brave men, women and children depends on you!!!
GOOD LUCK!
