【python】md5加密方法相关使用

  md5方法在hashlib库中,使用前需要先导入。它的主要方法为update,copy,以及转换为二进制,十六进制。

 

用法说明:

Help on HASH object:

class HASH(builtins.object)
 |  A hash represents the object used to calculate a checksum of a
 |  string of information.
 |
 |  Methods:
 |
 |  update() -- updates the current digest with an additional string
 |  digest() -- return the current digest value
 |  hexdigest() -- return the current digest as a string of hexadecimal digits
 |  copy() -- return a copy of the current hash object

  

实例如下:

>>> from hashlib import md5
>>> e='lilip@email.com'
>>> print(e)
lilip@email.com
>>> e_encode=e.lower().encode('utf-8')
>>> print(e_encode)
b'lilip@email.com'
>>> e_md5=md5(e_encode)
>>> print(e_md5)
<md5 HASH object @ 0x0000000002961B20>
>>> e_hex=e_md5.hexdigest()           #转换为十六进制
>>> print(e_hex)
d56e0ee2ffdd3c8e8f75219044e6b781
>>> e_digest=e_md5.digest()   #转换为二进制 >>> print(e_digest) b'\xd5n\x0e\xe2\xff\xdd<\x8e\x8fu!\x90D\xe6\xb7\x81'
>>> e_copy=e_md5.copy() #copy用法 >>> print(e_copy) <md5 HASH object @ 0x0000000002961B48>
>>> print(e_md5) <md5 HASH object @ 0x0000000002961B20> >>> e_md5.update('test'.encode('utf-8')) #update用法 >>> print(e_md5) <md5 HASH object @ 0x0000000002961B20> >>> print(e_md5.hexdigest()) 8b3b5ccd79b8a1c6aa50e40ad1e479b8
