94)This problem explores the use of a one-time pad version of the Vigenre 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, the third with a shift of 5 letters, and so on. a) Encrypt the plaintext sendmoremoney with the key stream 9 0 1 7 23 15 21 14 11 11 2 8 9 b) Using the ciphertext produced in part (a), find a key so that the cipher text decrypts to the c) plaintext cashnotneeded
