implement a stream cipher that uses a linear congruential keystream
generator and a hashed key. Next you will modify the cipher in part 2 to operate as a block cipher that will shuffle
pairs of bytes within each block based on the keystream and will apply cipher block
chaining (CBC) between blocks.
