Python对数据加密与解密
1、base64模块>>>import base64
>>>s1 = base64.encodestring('Hello world') #加密过程
>>>print s1
>>>SGVsbG8gd29ybGQ=
>>>s2 = base64.decodestring(s1) #解决过程
>>>print s2
>>>Hello world
2、Crypto模块
>>> import Crypto
>>> 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
'\xd6\x83\x8dd!VT\x92\xaa`A\x05\xe0\x9b\x8b\xf1'
>>> obj2 = AES.new('This is a key123',AES.MODE_CBC,'This is an IV456')
>>> obj2.decrypt(ciphertext)
'The answer is no'
