For those who haven't managed yet to solve the new GCHQ crypto challenge
on
http://www.gchq.gov.uk/challenge.html
I have quickly written up the solution we found yesterday on
http://www.cl.cam.ac.uk/~mgk25/gchq-challenge.html
As GCHQ is surely able to log and trace accurately who accesses the
above URL on our server, it would be best not to look at it if you want
to apply and impress their recruiters with finding your own solution.
