- Instructions: 1. Read: Computer Security Fundamentals, 4th edition (Chapter Eight) 2. Answer: Answer the following questions: • Question 1: It is easy to use encryption to hide messages inside of other objects. Steganography is the art of hidden writing. You can get Hide In Picture (HIP) at https://hide-in-picture.soft112.com/.. You can then encrypt a message or even a program that can be extracted by using an encryption key. Download HIP, hide a text message in a picture, and send the picture and key to your classmate to see whether he can extract the secret message. How could you detect hidden messages in web page images? Individual Assignment 2 • Question 2: ROT13 is an interesting encryption algorithm in that it has no key. It uses a form of the Caesar cipher to encrypt text. Try encoding a message by entering text in the box at http://www.rot13.com/. Exchange your encrypted message with someone else in class. Then enter their coded message you've received into the text box.…Question # 3 Assume that Dominique and Pricilla agreed to use an auto key cipher with initial keyvalue k1 = 11.
