## What it is
ShadowTLS is a TLS camouflage proxy written in Rust that relays a real TLS handshake with a valid certificate of your choice to the firewall, then switches to relaying encrypted proxy traffic. It is deployed on both sides of a firewall and is designed to be paired with an encryption proxy such as Shadowsocks, which it does not include itself.

## Use cases
- hide proxy traffic behind a real TLS handshake with a trusted certificate
- bypass DPI and active probing of proxy servers
- use someone else's valid TLS certificate without signing your own
- pair with shadowsocks to build a censorship-resistant tunnel
- deploy a trojan-like proxy without managing certificates

## When to choose
- you need TLS-level obfuscation that survives active probing and shows a real valid certificate
- you already run an encrypted proxy like shadowsocks and want to wrap it in TLS camouflage
- you deploy on Linux or macOS servers and clients with Docker or prebuilt binaries

## When to avoid
- you need Windows support, which is not available due to the monoio runtime
- you want an all-in-one proxy with built-in encryption and request encapsulation
- you need a simple setup without deploying components on both sides of the firewall
