⚠ 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 ?!)

It also allow you to deploy a free and fast vless like proxy in cloudflare workers, just copy the worker.js to your worker and fill configs accordingly it will do the rest

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

You can build CLI debug and release version as:

  git clone https://github.com/uoosef/bepass.git
  cd bepass/bepass
  make # For CLI debug version
  make release # For CLI Release version

You can build GUI debug and release version as:

  git clone https://github.com/uoosef/bepass.git
  cd bepass/bepass
  make gui # For GUI debug version
  make gui-release # For GUI release version

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/bepass
  go build ./cmd/cli/main.go

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/bepass
  go run ./cmd/cli/main.go -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],
  "WorkerAddress": "https://<YOUR_WORKER_ADDRESS>/dns-query",
  "WorkerIPPortAddress": "<CLEAN_CLOUDFLARE_IP>:443",
  "WorkerEnabled": true,
  "WorkerDNSOnly": true
}

If you cant find any working DOH Servers you can deploy worker.js code to your CF worker and change config.json accordingly

If you just want to use the DOH over worker set WorkerDNSOnly, true

{
  "WorkerDNSOnly": true
}

But if you want a full-fledged tcp socks5 proxy over worker set WorkerDNSOnly, false. please consider that your udp traffic wouldn't go through worker because cf doesn't support udp outgoing sockets currently

{
  "WorkerDNSOnly": false
}

• Self-Hosted DOH (DONE)
• TCP PROXY Over Worker (DONE)
• A GUI Version (WIP)
• An Android version (WIP)
• Finding a way to bypass the blocked ips

MIT go nuts!
