Cryptography Tutorial Try it Now! Algorithm Analysis Future Extensions Source Code Sources
Cracking the Code Project Abstract How do governments keep top-secret communications secure? How can they break into other governments' secret messages? Welcome to cryptanalysis, a disciple flourishing under the uniting of Computer Science and Mathematics. If either of these disiplines interest you (or just finding out other people's secrets), then Cracking the Code is the introduction into the field you need! The presentation begins with outlining basic cryptography principles, no background knowledge needed to understand. Then I will explain in-depth the entire process of encoding a text using an XOR encryption scheme and decoding the resulting message using various algorithms -- without knowledge of the encryption key used, thereby "cracking the code". Advice and Directions for Website Users: If you are not familar with cryptography, I would strongly recommend you view the Cryptography Tutorial prior to exploring the rest of the project details. However, you can also jump right in to the project and try encrypting a text and then decoding it by using my final graphical user interface (found by clicking on the "Try it Now!" link). I have also included the results of my analysis of the various solutions and suggestions for future extensions on the project. Finally, if you have not had enough fun by just looking at my algorithms and solutions, you can view all of my source code, fully documented. I have posted all code outright. Experiment with the code all you like, but please reference me if you use my work. I have cited the major sources I used throughout the project. Minor sources are cited within my text or code itself.
