DES has been around since 1976, and no significant weaknesses have been
No algorithm significantly better than trying all the 256 possible
keys have been discovered.
With the 8 bits from the clue, the search space is reduced to
248 = 281474976710656 keys.
Brute force seemed to be the only option for this stage, and we
immediately started on two tasks:
Up to now we felt that we had made progress, and in order to start this
monster run as soon as possible we split the implementation between
Staffan created the server, Fredrik wrote a screensaver client, and Gunnar
implemented the key tester.
Implementing an efficient key tester.
Creating a distributed system where a central server distributed
jobs to a large set of client computers.
