Bepass: A DPI bypassing tool!

This is a simple tool that utilizes tls client hello splitting attack inorder to bypass iran's dpi system, it won't work if target machine's ip is blocked(Yet ?!)

Features

• Supports all irans network careers with some tweaks in tls hello packet length
• DOH spport
• SDNS support
• Cross platform

Usage

Inorder to deploy this project you should first find a "DOH" or "SDNS" link that works on your career, then edit config.json and fill the "RemoteDNSAddr" field respectivce to the dns link that you found!

For Example the following configuration will most likely work on IR-MCI:

  {
  "TLSHeaderLength": 5,
  "RemoteDNSAddr": "https://1.1.1.1/dns-query",
  "DnsCacheTTL": 30,
  "BindAddress": "127.0.0.1:8085",
  "ChunksLengthBeforeSni": [1, 5],
  "SniChunksLength": [1, 5],
  "ChunksLengthAfterSni": [1, 5],
  "DelayBetweenChunks":   [1, 10]
}

Deployment

Just install go 1.19+ and run:

  go build .

It should gives you an executable file. or you can simple run it in place

  go run . -c config.json

Roadmap

• An android version

• Finding a way to bypass the blocked ip's
