python MD5值破解

from hashlib import md5
from string import ascii_letters,digits,punctuation
from itertools import permutations
from time import time
#生成暴力破解口令集
all_letters=ascii_letters+digits+punctuation+'.,;'
def decrypt_md5(md5_value):
    if len(md5_value)!=32:
        print('不是有效的md5值')
        return
    md5_value=md5_value.lower()
    for item in permutations(all_letters,5):#全排列
        item=''.join(item)
#        print(item)
        if md5(item.encode()).hexdigest()==md5_value:
            return item
md5_value  ='f7db3262ba19e2c1dcdaeefe69c688a1'

start=time()
result=decrypt_md5(md5_value)
if result:
    print('\n Success: '+md5_value+'==>'+result)
print('Time used:',time()-start)

運行結果：
