gquic_043_decrypt's Introduction

介绍

这是一个用于解密GQUIC协议Q043版本数据包的工具，基于gquiche实现，解密数据包的部分在gquiche/quic/proto_test目录下。该工具目前只是一个demo玩具，可能会存在或多或少的BUG。详细请参考这篇介绍文章一种对QUIC协议的抓包方案（拿某知名APP练手）

环境准备

安装下列依赖库

apt-get install cmake build-essential protobuf-compiler libprotobuf-dev golang-go libunwind-dev libicu-dev

编译安装pcap pp库
拉取源码

git clone https://github.com/aazhuliang/GQUIC_043_decrypt.git
git submodule update --init

编译

mkdir build && cd build  
cmkae -DPCAPPP_INCLUDE_DIRS=xxx -DPCAPPP_LIBRARY_DIRS=xxx ..
make -jx

使用方法

先修改config.h中的配置项

./quic_proto_test
python3 decode.py

客户端和服务端使用方法

A sample quic server and client implementation are provided in quiche. To use these you should build the binaries.

cd build
make simple_quic_server simple_quic_client
cd -

Download a copy of www.example.org, which we will serve locally using the simple_quic_server binary.

mkdir -p /data/quic-root
wget -p --save-headers https://www.example.org -P /data/quic-root

In order to run the simple_quic_server, you will need a valid certificate, and a private key is pkcs8 format. If you don't have one, there are scripts to generate them.

cd utils
./generate-certs.sh
mkdir -p /data/quic-cert
mv ./out/* /data/quic-cert/
cd -

Run the quic server

./build/simple_quic_server \
  --quic_response_cache_dir=/data/quic-root/ \
  --certificate_file=/data/quic-cert/leaf_cert.pem \
  --key_file=/data/quic-cert/leaf_cert.pkcs8

Request the file with quic client

./build/simple_quic_client \
  --disable_certificate_verification=true \
  --host=127.0.0.1 --port=6121 \
  "https://www.example.org/index.html"

You can also use chormium-based browsers to access simple_quic_server at 127.0.0.1:6121, and check the request/response protocol by DevTools -> Network panel.
