I ran my own blog from November 2006 till October 2014. All posts are still online, but I don't have time to update it anymore. Please note that all images and media files have been removed when the backup was moved to a new host in early 2016. Enjoy!
After watching David Finchers "Zodiak" last weekend I read some articles about the case and found a copy of the yet unsolved 340 character cipher. The fact that this cipher remains uncracked even 30 years after it had been created instantly fascinated me, and so I decided to take a closer look at it.
I don't think it will be possible to crack this one using simple brute force methods, as the number of possible combinations is just far too high. On the other hand I'm quite sure that it's too complex to be solved using pen and paper. I therefore created a quite simple script using a somewhat different approach.
I may tell you some more details about the script in future postings after having played around with it a bit, for now I'll just reveal that it's about 100 lines long and processing one series of words may take hours, days or even weeks depending on the complexity of the task.
During the next few weeks I'll feed it with some input, and I'm really curious to see what the output will be (well, probably junk, but you never know.
