## Description

Why You Need This:

- Capture on TCP/IP layer, NOT system proxy. Avoid some applications not going through the proxy
- Detect TLS connection and ALPN
- Only capture and decrypt HTTPS the address you specify, to prevent certain applications from malfunctioning due to addresses that cannot be captured by packet capture.
- Also support decrypt WebSocket

How it works:

- This app captures all IP packets (IP layer)
- Next assemble into TCP stream (TCP layer)
- Probe TLS connections and ALPN information to help you determine if there's any possibility of packet capture.
- Next assemble into HTTPS/WebSocket packet (Application layer) if you MITM it
