Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data. A simple encryption method might take plaintext and mix up the letters using some predetermined pattern and then use that pattern to decrypt the data for reading. Ciphers are the algorithms used to put the data into its secret pattern and then systematically decrypt it for reading. This script is going to use a famous simple cipher called the Caesar Cipher. It is a substitution cipher where each letter in the text is 'shifted' in a certain number of places. It uses the alphabet as the primary pattern and then based on the shift number, it would shift all the letters and replace the alphabet with our pattern. For example, if our shift number was 3, then A would be replaced with D, if we performed a right shift. As an example: Text = "THE CAT IS VISIBLE AT MIDNIGHT" Ciphertext = "WKH FDW LV YLVLEOH DW PLGQLIJKW" The keys to decrypt this message are the shift number…

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.…
