Python之路——hmac模块

 1 import hmac
 2 import os
 3 c = os.urandom(24)  # 返回一个随机的32字节的二进制数，可以应用于密码相关的方面
 4 name = b‘liuyk‘
 5 h = hmac.new(name,c)
 6 digest = h.digest() # This returns a string containing 8-bit data.  The object is
 7                     # not altered in any way by this function; you can continue
 8                     # updating the object after calling this function.
 9 h.update(b‘hahaha‘)
10 print(digest)
11 print(h.digest())
12 print(h.hexdigest(),len(h.hexdigest()))
