Encryption using rotate operations write a program that performs simple encryption by rotating each plaintext byte a varying num ber of positions in different directions. for example, in the following array that represents the encryption key, a negative value indicates a rotation to the left and a positive value indicates a rotation to the right. the integer in each position indicates the magnitude of the rotation: byte, 4, 1, 0, -3 , 5, 2, -4, -4, 6 your program should loop through a plaintext message and align the key to the first 10 bytes of the message. rotate each plaintext byte by the amount indicated by its matching key array value. then, align the key to the next 10 bytes of the message and repeat the process . (a video for this exercise is posted the web site.)
