3. What is Cryptography?
The art of protecting information by transforming it into an unreadable format, called cipher text. Only those who possess a secret key can decipher the message into plain text.
Encrypted messages can sometimes be broken by cryptanalysis, also called codebreaking, although modern cryptography techniques are virtually unbreakable.

5. Why is it important?
Cryptography makes secure web sites and electronic safe transmissions possible
protects by rendering it very difficult to read by any unintended party

6. Where did it come from? Caesar's Alphabet
ABCDEFGHIJKLMNOPQRSTUVWXYZ DEFGHIJKLMNOPQRSTUVWXYZABC
Every third letter the alphabet shifts to the left
Basic example :
My name is Tamara Smith
PB QDPH LV WDPDUD VPLKW

7. Who uses it?
Governments
Spies
Banks
Credit card companies
You

8. Modern Cryptography Systems
Substitution Cipher
Switch from one letter to another
Easily broken
Reciprocal Cipher
Make systems less secure or more usable
You can enter clear text and get cipher text or vice versa
Form of cryptographic suicide

9. Symmetric Cipher Asymmetric Cipher
Uses the same key for encryption and decryption
Asymmetric Cipher
Split key algorithm
Public key
Private key

10. Conclusion
Billions of dollars are spent on computer security, and most of that money is wasted on insecure products. The question remains, how technologically advanced will cryptography become?. Currently encryption standards appear nearly unbreakable. Everyday new technology is either invented, changed or updated. There are many people out there who try to hack into the networks, whether its wireless networks, network systems or something as simple as an . The way in which cryptography is used will continue to change as our society pushes for more security in everyday life.
