Chaussette

Chaussette is a proxy which takes SOCKS5 requests and proxies them to CONNECT over HTTP. It is designed for use with Cloudflare services which support CONNECT over HTTP such as the Privacy Edge proxies. Chaussette will also allow the passing of a GeoHash hint which will instruct the Cloudflare privacy proxy into which geography the requests proxied by Chaussette should egress.

Getting Started

The proxy takes in some configuration from the command line, and some configuration from Environent Variables.

Usage

chaussette [OPTIONS] --listen-addr <LISTEN_ADDR> [MASQUE_PRESHARED_KEY] [CLIENT_CERT] [CLIENT_KEY]
