为了练习python，强迫自己能用Python的题都用python解题还有各种密码
实验吧题目：信息保密的需求和实际操作自古有之，与之相应的信息加密与解密也是历史悠久，现有一段经过古典密码理论（不止一种）加密的密文，内容如下：
89 51 82 109 89 50 86 122 97 71 107 61请找出这段密文隐藏的消息明文
1.数字都没有超过127,ASCII码，解出来base64，然后再转得到flag
1 import base64 2 s="89 51 82 109 89 50 86 122 97 71 107 61" 3 s=s.split() 4 d = "" 5 for i in s: 6 d+=(chr(int(i))) 7 print(d) 8 print(base64.b64decode(d))
实验吧题目：YMFZZTY0D3RMD3RMMTIZ 这一串到底是什么！！！！为什么这么像base32却不是！！！ 明文的md5值为16478a151bdd41335dcd69b270f6b985
1.给了一段全字母全大写的字符串，提示说像base32，后来试了一下错误的，后面有md5值，网上搜了一下直接解出来了。起始作者的思路
2 爆破列出所有的字符串组合的MD5值和给出的md5比较，如果相等，返回原字符串，得出flag，上代码
import base64 import hashlib import itertools pwd ="YMFZZTY0D3RMD3RMMTIZ" tables =[] #检查md5值是否相同 def check(src): m1 =hashlib.md5() m1.update(src) ans =m1.hexdigest() if ans =="16478a151bdd41335dcd69b270f6b985": return 1 else: return 0 #生成字符串的列表 def generateTable(string): lists=[] for i in range(len(string)): if str.isupper(string[i]): lists.append([str.lower(string[i]),string[i]]) else: lists.append([string[i]]) print(lists) #generateTable(pwd) lists=itertools.product([‘y‘, ‘Y‘], [‘m‘, ‘M‘], [‘f‘, ‘F‘], [‘z‘, ‘Z‘], [‘z‘, ‘Z‘], [‘t‘, ‘T‘], [‘y‘, ‘Y‘], [‘0‘], [‘d‘, ‘D‘], [‘3‘], [‘r‘, ‘R‘], [‘m‘, ‘M‘], [‘d‘, ‘D‘], [‘3‘], [‘r‘, ‘R‘], [‘m‘, ‘M‘], [‘m‘, ‘M‘], [‘t‘, ‘T‘], [‘i‘, ‘I‘], [‘z‘, ‘Z‘]) for i in lists: temp=‘‘.join(i) if check(base64.b64decode(temp)) ==1: print(bytes.decode(base64.b64decode(temp)))
