Welcome!

The 2019 NSA Codebreaker Challenge has ENDED


We hope everyone enjoyed the challenge this year and thanks for all of your hard work and dedication. Also, congratulations to the University of North Georgia on their top place finish! We have never had such a high combined participation and performance by a single university in the history of the Codebreaker Challenge. Well done!

We realize some of you may want to continue working on the challenge even though the competition has ended. That’s great! We will leave the site up so you can continue submitting answers. However, no new points will be added to your school total and we will also be disabling new registrations to reduce overall server load and support. Thanks again and we look forward to bringing you the next challenge later this year!

All the best,
The NSA Codebreaker Team
