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

用于加密相关的操做，代替了md5模块和sha模块，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())

以上加密算法虽然依然很是厉害，但时候存在缺陷，即：经过撞库能够反解。因此，有必要对加密算法中添加自定义key再来作加密。

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

python内置还有一个 hmac 模块，它内部对咱们建立 key 和 内容 进行进一步的处理而后再加密

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