Implement a stream cipher in Python that (1) allows the user to input a plaintext, (2)generates a random keystream of the same length as the user-entered plaintext, (3)encrypts the plaintext by applying the bitwise XOR (exclusive or) operation between the plaintext and the generated keystream, (4) prints out the generatedkeystream and the produced ciphertext.
