Python aes encryption

Aes in python

>>> from Crypto.Cipher import AES
>>>
>>> key = b'Sixteen byte key'
>>> cipher = AES.new(key, AES.MODE_EAX, nonce=nonce)
>>> plaintext = cipher.decrypt(ciphertext)
>>> try:
>>>     cipher.verify(tag)
>>>     print("The message is authentic:", plaintext)
>>> except ValueError:
>>>     print("Key incorrect or message corrupted")
