## Description

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 unstable environments using automatic reconnection strategies with exponential backoff. Security is enforced through TLS-secured tunnels and credential-based authentication, which allows administrators to restrict access to specific network destinations or port ranges based on user identity.

Beyond its core tunneling capabilities, the software supports SOCKS5 proxy integration, allowing applications to route traffic through remote endpoints as if they were connected to a local network. It is designed for broad compatibility, offering support for cross-platform binary distribution and containerized deployment to ensure consistent operation across diverse infrastructure.
