Cutting Edge Cracking
One of our competitors, Cribbage, from the 2018 competition kindly wrote up how they tackled the final challenge last year. If you are wondering what it takes to decipher a message encrypted with a brand new code then this might give you some idea.

Rules of Engagement
While we try to keep things simple and friendly, the competition has some rules and you should probably know about them.

In the meantime you can read them here.
Programming for Code Breakers
National Cipher Challenge alumnus Julian Bhardwaj wrote a rough guide to computer programming for code breakers which he has kindly allowed us to post here for you.

Welcome back to the National Cipher Challenge, I can’t believe we are now in the 18th year of the competition. Back in 2005 we travelled with Harry deep under the Arctic to the Lomonosov Ridge, as he worked to recover a Soviet spy satellite that had crashed in the northern waters. The mission took place in 1957 and this year’s competition starts as Harry returned to the US to receive his new assignment. You will be working with him to … Read on
Everyone. Everyone who took part in this year’s challenge, including me. At least, I hope so. It has been a real pleasure watching you all struggle, strive and succeed, and I hope you enjoyed it as much as I did. Of course we do have some prizes to award, so without much further ado, but with a flourish and a fanfare, here they are. The GCHQ Prize of £1,000 is awarded to Claire Carlotti (Kalicali) of Sir Roger Manwood School. … Read on
