hashlib模块

md5加密

import hashlib

s = 'day9test'

md5_obj = hashlib.md5()
md5_obj.update(s.encode('utf-8'))
print(md5_obj.hexdigest())

md5_2 = hashlib.md5()
md5_2.update('day9'.encode('utf-8'))
md5_2.update('test'.encode('utf-8'))
print(md5_2.hexdigest())

 

加盐：

hashlib.md5("salt".encode("utf8"))
