Using the simplified RC4 Algorithm of 8 bytes (rather than the full 256 bytes), find the final Keystream and Cipherpext of the following Input string:   S-Array of length 8, [S0 S1 S2 S3 S4 S5 S6 S7] = [7 6 5 4 3 2 1 0] Key, K = [3 1 4 1 5] Plaintext, PT = [6 1 5 4]   Hint: For the simplified stream generation, you can use this pseudocode (only up to the PT length):                         /* Initialization */ set i and j = 0                 for i = i + 1 to length of PT                        j = j + S[i] mod 8                        swap S[i], S[j]                            t = S[i] + S[j] mod 8
