CTF之md5截断比较验证填坑

import hashlib
addStr = ‘lll’ #加起来的字符串
knowMd5 = ‘d3b6da’ #知道的md5
dict = ‘abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ’

def md5(text):
    return hashlib.md5(str(text).encode(‘utf-8’)).hexdigest()

for i in dict:
    for j in dict:
        for k in dict:
            for l in dict:
                x = i + k + j + l
                b = x + addStr
                codeMd5 = md5(b)
                if codeMd5[:6] == knowMd5: #这里的6,是题目里的前几位
 print(x)
