支持缓冲区API的对象需要sha256错误

Question

我想散列一些4位数但它给了我(需要支持缓冲区API的对象(错误

这是我的代码

import hashlib
import itertools as it
number=[0,1,2,3,4,5,6,7,8,9]
code = hashlib.sha256()
passwords = list(it.permutations(number, 4))
#hpass is hash password
for hpass in passwords :
code.update(passwords)

print(hpass)

输出为

Traceback (most recent call last):
File "c:UsersParsaDesktopprojectUntitled-2.py", line 11, in <module>
code.update(passwords)
TypeError: object supporting the buffer API required

Answer 1

hashlib.sha256实例的更新函数需要像对象一样的字节

使用类似字节的对象更新哈希对象。https://docs.python.org/3/library/hashlib.html

而且似乎在更新时输入密码列表

很难知道代码的意图。但我想你想得到一组4位数的散列如果是对的，试试这个。

import hashlib
import itertools as it
number=[0,1,2,3,4,5,6,7,8,9]
passwords = list(it.permutations(number, 4))
# hpass is hash password
for hpass in passwords :

encoded_hpass = ''.join(map(str, hpass)).encode('ascii')

code = hashlib.sha256()
code.update(encoded_hpass)

print(encoded_hpass)
print(code.digest())

输出
