1. proxy client is running at your local computer.

   It receive your app (like a browser) request, encrypt the data, send to proxy server

2. proxy server receive the request from proxy client, decrypt it, and sent to the target host.

3. proxy server got the response from target host, then encrypt response, send back to proxy client.

4. proxy client decrypt response received from proxy server, and send to local app.

5. the circle done.

Usage

Server side

1. cp config.ini.example config.ini,

   config.ini

   • openssl genrsa -out privkey.pem 2048
   • openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095
   • server. Server ip
   • server_port. Default 7070
   • local. Client ip, default 127.0.0.1
   • local_port. Defalut 1080
   • certfile. Default cacert.pem
   • keyfile. Defalut privkey.pem

2. python server.py

Local side

1. use same of server config file

2. python client.py

3. Done

Now, you can set your apps (e.g. Browser) Using socks5 proxy.

IP = 127.0.0.1 PORT = 1080 (if not changed in the config.cfg)

TODO

• Use SSL encrypt the data
