Johnny needs your help (again). Write a Python program that uses the cryptography.io API to encrypt plaintext 'Crypto is fun and entertaining' using 3DES in OFB mode with the following combination of keys and nonce: k = b'12345678' nonce = b'12345678' ci = ? #this is the ciphertext k = b'12345678abcdefghabcdefgh' nonce = b'12345678' c2 = ? #this is the ciphertext k = b'abcdefghabcdefgh12345678' nonce = b'12345678' c3 = ? #this is the ciphertext Is there anything to explain to Johnny about ciphertexts c1, c2, and c3? Submit your Python code (py). Your response should be submitted as comments within your code, as well as the values you obtained for c1, c2, and c3 in byte format (e.g., b'\x98x\xc3\xc3\xb7.>H\xlb\xdeY/X\xee-\xbb
