DarkFlare

DarkFlare Firewall Piercing (TCP over CDN) 

It has two parts: a client-side proxy (darkflare-client) that encodes TCP data into HTTPS requests and sends it to a Cloudflare-protected domain, and a server-side proxy (darkflare-server) that decodes the requests and forwards the data to a local service (like SSH on port 22). It’s protocol-agnostic, secure, and uses Cloudflare's encrypted infrastructure, making it stealthy and scalable for accessing internal resources or bypassing network restrictions.
