python学习笔记十七：base64及md5编码

一、Python Base64编码

#-*- coding: utf-8 -*-
import base64

str = 'cnblogs'
str64 = base64.b64encode(str)
print str64                     #Y25ibG9ncw==
print base64.b64decode(str64)   #cnblogs

二、MD5

#Python 2.x
import hashlib
print hashlib.md5("whatever your string is").hexdigest()

#Python 3.x
import hashlib
print(hashlib.md5("whatever your string is".encode('utf-8')).hexdigest())
