hashlib

hashlib - hashlib module - A common interface to many hash functions

hashlib模块是一个很多hash函数的通用接口，提供了md5, sha1, sha224, sha256, sha384, sha512等加密算法，主要用来加密。

############# md5 #############
>>> import hashlib
>>> m = hashlib.md5()
>>> m.update(bytes('passwd', encoding='utf-8'))
>>> m.hexdigest()
'76a2173be6393254e72ffa4d6df1030a'

############# sha1 #############
>>> m = hashlib.sha1()
>>> m.update(bytes('passwd', encoding='utf-8'))
>>> m.hexdigest()
'30274c47903bd1bac7633bbf09743149ebab805f'

############# sha256 #############
>>> m = hashlib.sha256()
>>> m.update(bytes('passwd', encoding='utf-8'))
>>> m.hexdigest()
'0d6be69b264717f2dd33652e212b173104b4a647b7c11ae72e9885f11cd312fb'

############# sha384 #############
>>> m = hashlib.sha384()
>>> m.update(bytes('passwd', encoding='utf-8'))
>>> m.hexdigest()
'851fab8375c23d5749c028b18f2844e754c30af17a11df995ea4faa8743ea67bb0ebf920332d9473d78bbdf9f47657ca'

############# sha512 #############
>>> m = hashlib.sha512()
>>> m.update(bytes('passwd', encoding='utf-8'))
>>> m.hexdigest()
'bf98889d70675da7dc753cdf8ac78c49cdcced21919dce21b83dc8c81607e4eaf719aa5f9bc09bbe316d8e98f663c607cfc6eb4337eaa41601cd9bc303c5f583'

写一个封装md5加密的函数

import hashlib

def _encrypt(field):
　　m = hashlib.md5()
　　m.update(bytes(field, encoding='utf-8'))
　　return m.hexdigest()
