hashlib模块

 1 import hashlib
 2 
 3 m = hashlib.md5()
 4 
 5 print(m)
 6 
 7 m.update(‘hello world‘.encode(‘utf8‘))
 8 print(m.hexdigest())
 9 
10 m.update(‘nizhipeng‘.encode(‘utf8‘))
11 print(m.hexdigest())
12 
13 #上下结果一致
14 m1 = hashlib.md5()
15 m1.update(‘hello worldnizhipeng‘.encode(‘utf8‘))
16 print(m1.hexdigest())
17 
18 
19 s = hashlib.sha256()
20 s.update(‘hello world‘.encode(‘utf8‘))
21 print(s.hexdigest()) #不可逆

加密。
