⚠ WARNING: This is an EXPERIMENTAL Project, use it at your own risk!

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

• Supports all Iran's network careers with some tweaks in tls hello packet length
• DOH support
• SDNS support
• Cross platform

You can download the latest build from release or Just install go 1.19+ and run:

  git clone https://github.com/uoosef/bepass.git
  cd bepass/cmd/bepass
  go build .

It should give you an executable file, or you can simply run it in place.

  git clone https://github.com/uoosef/bepass.git
  cd bepass/cmd/bepass
  go run . -c config.json

In order to deploy this project, you should first find a "DOH" or "SDNS" link that works on your ISP, then edit config.json and fill the "RemoteDNSAddr" field with 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]
}

• Self-Hosted DOH (WIP)

• An android version (WIP)

• Finding a way to bypass the blocked ips

MIT go nuts!
