This problem explores the use of a one-time pad version of the Vigenere cipher. In this scheme, the key is a stream of random numbers between 0 and 26. For example, if the key is 3 19 5 ..., then the first letter of plaintext is encrypted with a shift of 3 letters, the second with a shift of 19 letters, and so on.

(a) Encrypt the plaintext cryptography with the key stream 3 19 5 20 8 12 10 23 6 11 13 7.

(b) Using the ciphertext produced in part a, find a key so that the ciphertext decrypts to plaintext kennesawuniv
