从 SHA3-512 哈希值生成密码

问题描述

我是 Python 新手，目前正在攻读 IT 硕士学位。我正在从哈希值解码密码。

这就是我目前的设置方式。我知道这是错误的，任何帮助将不胜感激。

import itertools
import time
from Crypto.Hash import SHA3_512

# Function to brute force the password
def tryPassword(passwordSet):
    start = time.time()

    # Allowed characters in the password
    chars = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMnopQRSTUVWXYZ`~!@#$%^&*()_-+=[{]}|:;'\",<.>/?"
    
    attempts = 0

    for value in range(1,9):
        # Build up a string to test against,character by character
        for letter in itertools.product(chars,repeat=value):
            attempts += 1
            letter = ''.join(letter)
            hash_object = SHA3_512.new()
            hash_object.update((letter).encode("utf-8"))

            tmp_hash = hash_object.hexdigest()
            print(tmp_hash)

            #if the string we are building matches the password given to us,return from the function
            if tmp_hash == passwordSet:
                end = time.time()
                distance = end - start
                return (attempts,distance)


password = input("Password >")
tries,timeAmount,= tryPassword(password)
print("The password %s was cracked in %s tries and %s seconds!" % (password,tries,timeAmount))

解决方法

由于目的是破解散列密码，所以应该是函数的参数，而不是明文密码。

然后在循环中它需要对每个候选密码进行散列，并将散列与输入进行比较。
