## What it is
Corkscrew is a small C command-line tool that tunnels SSH connections through HTTP proxies by acting as an SSH ProxyCommand helper. It supports optional HTTP proxy authentication via a credentials file and runs on many Unix-like platforms.

## Use cases
- tunnel ssh through an http proxy
- use ssh behind a corporate firewall
- configure ssh ProxyCommand for http proxy
- ssh through proxy with authentication
- bypass restrictive network to reach ssh servers

## When to choose
- you need SSH access from a network that only allows HTTP proxy traffic
- you want a tiny, dependency-free ProxyCommand helper
- your proxy requires basic HTTP authentication

## When to avoid
- you need SOCKS or HTTPS CONNECT with advanced features
- you want a full VPN or general-purpose tunneling solution
- you need actively developed tooling with modern proxy protocol support
