Data Security and Encryption

After learning about hacking and how it compromises data security, we will learn about the next step in protecting data, by means of encryption. The very ancient and often used in technique of cryptography involves scrambling messages in such a way that only the parties within the communication or, in our case, a computer algorithm and users know how to decode them effectively.
We will first learn the basics on cryptography from the Encryption Tutorial. Another simple source is What is Cryptography? at WiseGeek.
Subsequently, we will try our skills at decrypting through the CRYPTOCOM Game.
