Chisel is a network tunneling tool that facilitates secure communication by encapsulating TCP and UDP traffic within HTTP requests. It functions as a connection multiplexer, consolidating multiple logical network streams into a single persistent connection to improve throughput and reduce overhead. By leveraging standard web protocols, the system enables firewall traversal and provides a mechanism for remote port forwarding and proxying. The project distinguishes itself through its focus on resilient connectivity and granular access control. It maintains persistent network sessions across uns

Network Pivoting Toolkit

Secure Socket Funneling - Network tool and toolkit - TCP and UDP port forwarding, SOCKS proxy, remote shell, standalone and cross platform

reGeorg is an HTTP tunneling proxy and network tunneling tool designed to route network traffic to internal targets. It functions as a remote port forwarder that wraps socket communication within HTTP requests to bypass firewalls. The tool includes a SOCKS5 proxy server implementation that converts tunneled traffic into a usable interface. This allows external networking tools to route data through a remote host into restricted internal network boundaries. The project provides capabilities for network pivoting, including generic network tunneling and SOCKS proxy configuration to facilitate c
