Burpsuite配合mitmproxy实现数据加解密教学文档<\/h1>

1. 实现原理概述<\/h2>
Burpsuite通过上游代理(Upstream Proxy)将请求转发给mitmproxy代理，mitmproxy通过加载自定义的加解密脚本实现对请求和响应数据的加解密处理，然后将处理后的请求转发给目标服务器。<\/p>

2. 环境准备<\/h2>

2.1 安装mitmproxy<\/h3>

pip install mitmproxy
<\/span><\/span><\/code><\/pre>安装完成后，mitmproxy提供三个可执行命令：<\/p>

mitmproxy<\/code>：命令行界面版本<\/li>
mitmweb<\/code>：Web界面版本<\/li>
mitmdump<\/code>：无界面版本<\/li>
<\/ul>
2.2 Burpsuite配置<\/h3>

打开Burpsuite<\/li>
进入"User options"选项卡<\/li>
找到"Upstream Proxy Servers"设置<\/li>
添加mitmproxy作为上游代理：

目标主机：通常设置为*<\/code>（所有请求）<\/li>
代理主机：127.0.0.1<\/code><\/li>
代理端口：mitmproxy监听的端口（如8888）<\/li>
<\/ul>
<\/li>
<\/ol>
3. mitmproxy启动方式<\/h2>
3.1 命令行启动<\/h3>
mitmproxy.exe -p 8888<\/span> -s md5.py
<\/span><\/span><\/code><\/pre>3.2 Web界面启动<\/h3>
mitmweb.exe -p 8888<\/span> -s md5.py
<\/span><\/span><\/code><\/pre>参数说明：<\/p>

-p<\/code>：指定监听端口<\/li>
-s<\/code>：指定加载的脚本文件（加解密脚本）<\/li>
<\/ul>
4. 加解密脚本开发<\/h2>
4.1 基本结构<\/h3>
一个完整的mitmproxy加解密脚本包含以下部分：<\/p>
from<\/span> mitmproxy import<\/span> http, ctx
<\/span><\/span>
<\/span><\/span>class<\/span> AddonName<\/span>:
<\/span><\/span>    def<\/span> request<\/span>(self, flow: http.<\/span>HTTPFlow) -><\/span> None<\/span>:
<\/span><\/span>        # 请求处理逻辑<\/span>
<\/span><\/span>        pass<\/span>
<\/span><\/span>    
<\/span><\/span>    def<\/span> response<\/span>(self, flow: http.<\/span>HTTPFlow) -><\/span> None<\/span>:
<\/span><\/span>        # 响应处理逻辑<\/span>
<\/span><\/span>        pass<\/span>
<\/span><\/span>
<\/span><\/span>addons =<\/span> [AddonName()]
<\/span><\/span><\/code><\/pre>4.2 MD5加密示例<\/h3>

# -*- coding: utf-8 -*-<\/span>
<\/span><\/span>from<\/span> mitmproxy import<\/span> http, ctx
<\/span><\/span>import<\/span> hashlib

<\/span><\/span>        data =<\/span> flow.<\/span>request.<\/span>text
<\/span><\/span>

<\/span><\/span>        d =<\/span> data.<\/span>split('='<\/span>)
<\/span><\/span>        
<\/span><\/span>        # 通过md5_encryption加密方法对明文密码加密<\/span>
<\/span><\/span>        md5_pass =<\/span> md5_encryption(d[3<\/span>])
<\/span><\/span>        
<\/span><\/span>        # 将加密后的密文重新赋值给数组<\/span>

<\/span><\/span>        flow.<\/span>request.<\/span>text =<\/span> data
<\/span><\/span>        
<\/span><\/span>        # 调试信息输出（可选）<\/span>
<\/span><\/span>        # info = ctx.log.info<\/span>

<\/span><\/span>params['token'<\/span>] =<\/span> md5_encryption(params['token'<\/span>])
<\/span><\/span>flow.<\/span>request.<\/span>text =<\/span> '&'<\/span>.<\/span>join([f<\/span>"<\/span>{<\/span>k}<\/span>=<\/span>{<\/span>v}<\/span>"<\/span> for<\/span> k, v in<\/span> params.<\/span>items()])
