Part 1: Encrypt the message CINEMA using RSA with n = 17 * 11 and e = 13, use A =10...Z = 35, work in blocks of one letter each.

Part 2: Decrypt the message 088-164-051-164-021-074 using the same parameters from part 1.

8. (20 pts) a. RSA encryption. Let n = pq = (7)(17) = 119 and e = 5 define a (very modest) RSA public key encryption. Since 25 < 119 < 2525, we can only encode one letter (two digit representation) at a time. Use the function ? = ? mod ? to encode the word MATHY into a series of five numbers that are less than n. b. To decrypt an RSA encrypted message, we need to find d,...

Write a Java program to encrypt the following message using the RC4 cipher using key CODES: Cryptography is a method of protecting information and communications through the use of codes so that only those for whom the information is intended can read and process it. Instead of using stream length 256, we will use length 26. When encrypting, let A = 0 to Z = 25 (hence CODES = [2 14 3 4 18]). Ignore spaces and punctuations and put...
