An example usage of an encryption algorithm (AES, in this case) is:

pycrypto 2.6.1 : Python Package Index

An example usage of an encryption algorithm (AES, in this case) is:

>>> from Crypto.Cipher import AES
>>> obj = AES.new('This is a key123', AES.MODE_CBC, 'This is an IV456')
>>> message = "The answer is no"
>>> ciphertext = obj.encrypt(message)
>>> ciphertext
'xd6x83x8dd!VTx92xaa`Ax05xe0x9bx8bxf1'
>>> obj2 = AES.new('This is a key123', AES.MODE_CBC, 'This is an IV456')
>>> obj2.decrypt(ciphertext)
'The answer is no'
