如何使我的Python密码破解程序更高效地运行？

Question

不久前，我对制作一个伪密码破解程序感兴趣。 下面是一些代码：

list = [ '1', '2', '3', '4', '5', '6', '7', '8', '9', '0', 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'] # giving it a list 

passlength = int(input('Length of string: ')) # length of code or no of objects
aspass = '' # empty string acts as assumed password
passs = input('Please input password ') # he infamous password
b = [] # the list that will stores randomly generated passwords as values
attempt = 0
digits = 0   
o = True
while o:
    for k in range(0, passlength): # run this loop as many times as the length of password
        x = str(random.choice(list))#the attempted upon digit in the password
        aspass += x
        digits += 1 # counts the step the cracker is on
        #print(aspass)
        if(len(aspass) > passlength or aspass in b):
            digits = 0
            attempt += 1
            break
        else:
            continue
        #b.append(aspass)
    if(aspass == passs):
        break
        o = False
        end()
    else:
        b.append(aspass)
        aspass = ''
        continue

这里的问题是，一切正常，它生成2个字符串密码。但是，如果长度超过2或3个字符串。嗯，它的移动速度有点慢。然后我有了一个想法，如果我能将随机生成的密码保存在我制作的“b”列表中，并确保该列表中的密码在这个过程中不会重复，那么我认为它会运行得更快

由于我是一个完全的初学者，我不知道如何以其他方式使它更快。我可以尝试哪些方法（例如可导入的模块）来改进这一点

破解密码并非易事。考虑一下随着密码长度的增长，您必须通过的搜索空间。您的可能字符列表包含26个字母和10个数字（顺便说一下，您可以使用string.digits和string.ascii_lowercase）。因此，对于密码中的第一个字符，有36个选项。第二个有36个选项，第三个有36个选项，依此类推。因此，对于长度为n的密码，您将有3^n个选项。正如你很快就能看到的，这个数字正在以极快的速度增长，即使是小数字

破解密码的方法称为Brute-force attack，效率极低，特别是考虑到大多数密码不是以明文形式存储的，而是以散列字符串形式存储的

其他注释很少：

1. 你的名字不太好。它们中的大多数都是无意义的，这使得代码更难理解
2. 您选择随机字符串，而不是按顺序浏览所有可能的选项。使用此方法无法覆盖所有选项。您可以使用itertools.permutations对所有选项进行迭代
3. 不要在if语句中使用括号，这不是Python的方式。求你了

我做了一个程序，我想做GUI，但如果你需要它，你可以从命令lilne使用它

 try:
    import string
except:
    print("please install strings lib with command <sudo pip3 install ")
try:
    import random
except:
    print("please install random lib with command <sudo pip3 install random>1")
try:
    import os
except:
    print("pleas install the os lib with command <sudo pip install os>")

这个怎么样：

import pyautogui
import time
import random

chars = "abcdefghijklmnopqrstuvwxyz"
chars_list = list(chars)

password = pyautogui.password("Enter a Password : ")

guess_password = ""

while(guess_password != password):
    guess_password = random.choices(chars_list, k=len(password))

    print("DECRYPTING"+ str(guess_password)+ "PASSWORD")

    if(guess_password == list(password)):
        print("Your password is : "+ "".join(guess_password))
        break
