CTF常用工具之汇总

前言：因为最近在玩一下CTF(sql注入是真的不会玩呀？(T_T) (T_T) )所以经常会用到一些像什么进制转换呀？base64 32 16编码解码呀？当然这些工具网上都有！但是每次都打开网页 总是感觉很麻烦所以就萌生了一个想法能不自己写一个脚本把这些功能集合在一起！就像kali里面的工具一样！这样的话想用的时候岂不是很方便？所以从昨天下午开始写到今天上午中午终于把这个工具脚本写完了！我们先看一下预览图

 

      当然这里只是集成我自己常用的一些功能！如果你们需要扩容也是非常容易的，

(1)    首先说一下这个脚本需要的包

import hashlib

import base64

from urllib import quote,unquote

import argparse

此工具需要运行在python3的环境下

(2)    下面就是代码部分，里面有详细的注释，如果还是看不懂代码里面有我的QQ

(3) 下面贴几张工具使用图

图一ASCII与字符之间的转换图

图二 ，十进制与其他进制之间的转换图

后言：该工具的扩展性还是非常强的！你们完全可以根据自己的需要在里面加一些经常用到的功能！

哎。。。要回去看sql注入的文章了！sql注入是真的不会玩呀~~>_<~~
