# YT-DPI v2.2.0
[](https://t.me/YT_DPI)
[[Русский](README_ru.md)] | [[Telegram](https://t.me/YT_DPI)]
**YT-DPI** is a professional forensic network diagnostic framework designed to dissect and identify Deep Packet Inspection (DPI) and TSPU interference. Unlike standard tools that rely on high-level OS libraries, YT-DPI uses a low-level C# engine to simulate raw TLS handshakes, pinpointing exactly where and how your traffic is being manipulated.
## 🚀 Key Features (v2.2.0)
* **Low-Level TLS Engine (C#):** Built-in "Barebuh Pro" engine that manually constructs `ClientHello` packets. This bypasses Windows Schannel limitations and identifies subtle DPI blocks that standard tools miss.
* **Dynamic Responsive UI:** Automatically calculates table widths based on IP address lengths (IPv4/IPv6). Features an ultra-smooth real-time "Waterfall" results display.
* **Multi-Protocol Depth:** Independent testing of Port 80 (HTTP), Port 443 (TLS 1.2), and Port 443 (TLS 1.3) with a new **THROTTLED** status detection.
* **Dual-Stack Control:** Toggle between `IPv6 Priority` and `IPv4 Only` via the new Settings menu to find "holes" in ISP filtering.
* **PowerShell 7 (Core) Optimized:** Auto-detects and runs on `pwsh.exe` for enhanced socket performance and faster execution.
* **Universal Proxy Tunneling:** Full SOCKS5/HTTP support with improved SSL-over-Proxy handling for ISP/GEO metadata retrieval.
* **Forensic Deep Trace:** Custom L4 TCP Traceroute to identify the specific network hop where the DPI middlebox injects RST packets.
## 🧠 The Knowledge Base: Why YouTube Lags?
| Problem | Technical Explanation | Solution |
| :--- | :--- | :--- |
| **SNI Filtering** | ISP "reads" the hostname in cleartext. YT-DPI will show **DPI RESET**. | Use [GoodbyeDPI](https://github.com/ValdikSS/GoodbyeDPI) or [Zapret](https://github.com/bol-van/zapret). |
| **QUIC Blocking** | ISPs block UDP Port 443. YT-DPI identifies this via L4 timeouts. | Disable QUIC in `chrome://flags/#enable-quic`. |
| **Kyber Algorithm** | Post-Quantum packets break old DPI parsers. Causes **THROTTLED** status. | Disable Kyber in `chrome://flags/#enable-tls13-kyber`. |
| **IP/CDN Blocking** | Direct block of Google/CDN nodes. YT-DPI will show **IP BLOCK**. | Use a Proxy/VPN or advanced IP fragmentation. |
## 🛠 Usage & Hotkeys
1. **Run `YT-DPI.bat`** (No installation required).
2. **[ENTER]** — Start global multi-threaded scan.
3. **[S]** — **Settings:** Change IP preference (v4/v6) or clear network cache.
4. **[P]** — **Proxy:** Configure SOCKS5/HTTP tunnel with history support.
5. **[D]** — **Deep Trace:** Pinpoint the censorship node by domain index.
6. **[R]** — **Report:** Export forensic results to `YT-DPI_Report.txt`.
7. **[U]** — **Update:** Check for the latest version on GitHub.
