python md5

import hashlib
#obj = hashlib.md5(bytes('',encoding='utf-8'))
obj=hashlib.md5(bytes('123',encoding='utf-8'))
result = obj.hexdigest()
print(result)

hashlib

用於加密相關的操做，代替了md5模塊和sha模塊，主要提供 SHA1, SHA224, SHA256, SHA384, SHA512 ，MD5 算法

import hashlib   # ######## md5 ######## hash = hashlib.md5() # help(hash.update) hash .update(bytes( 'admin' , encoding = 'utf-8' )) print ( hash .hexdigest()) print ( hash .digest())     ######## sha1 ########   hash = hashlib.sha1() hash .update(bytes( 'admin' , encoding = 'utf-8' )) print ( hash .hexdigest())   # ######## sha256 ########   hash = hashlib.sha256() hash .update(bytes( 'admin' , encoding = 'utf-8' )) print ( hash .hexdigest())     # ######## sha384 ########   hash = hashlib.sha384() hash .update(bytes( 'admin' , encoding = 'utf-8' )) print ( hash .hexdigest())   # ######## sha512 ########   hash = hashlib.sha512() hash .update(bytes( 'admin' , encoding = 'utf-8' )) print ( hash .hexdigest())

以上加密算法雖然依然很是厲害，但時候存在缺陷，即：經過撞庫能夠反解。因此，有必要對加密算法中添加自定義key再來作加密。

import hashlib   # ######## md5 ########   hash = hashlib.md5(bytes( '898oaFs09f' ,encoding = "utf-8" )) hash .update(bytes( 'admin' ,encoding = "utf-8" )) print ( hash .hexdigest())

python內置還有一個 hmac 模塊，它內部對咱們建立 key 和 內容 進行進一步的處理而後再加密

import hmac   h = hmac.new(bytes( '898oaFs09f' ,encoding = "utf-8" )) h.update(bytes( 'admin' ,encoding = "utf-8" )) print (h.hexdigest())
