        minlength +=1
        if minlength > 5:
            generating = False
    return ''
                 
def gethash(word):
    hash_object = hashlib.sha1(word)
    pbHash = hash_object.hexdigest()
    return str(pbHash)​

答案7:

import string
import hashlib
from itertools import product

def password_cracker(hash):
    alphabet = string.ascii_lowercase
    
    for long in range(6):
    
        cases = product(alphabet, repeat = long)
    
        for case in cases:
        
            temp_hash = hashlib.sha1(''.join(case).encode('utf-8')).hexdigest()
            
            if(hash == temp_hash):
                return ''.join(case)​

答案8:

from itertools import product as P
from hashlib import sha1 as S
def password_cracker(h,A='abcdefghijklmnopqrstuvwxyz'):
    for i in range(6):
        for x in map(''.join,P(A,repeat=i)):
            if S(x.encode('ascii')).hexdigest()==h:return x​

答案9:

import hashlib
from itertools import product
from string import ascii_lowercase


def password_cracker(hash):
    for n in range(0,6):
        all = (''.join(i) for i in product(ascii_lowercase, repeat = n))
        for item in all:
            hash_object = hashlib.sha1(bytearray(item, 'utf-8'))
            check = hash_object.hexdigest()
            if check == hash:
                return item
                break​

答案10:
