history

Project history and usage

Ghostunnel is a Go TLS proxy for placing mutual TLS in front of services that do not speak TLS themselves.

Project history

The Ghostunnel repository was created in 2015 and its first GitHub release, v1.0.0, was published in 2016. Its README frames the project as a simple TLS proxy with mutual authentication for securing non-TLS backend applications.

The project evolved around two complementary modes: server mode terminates TLS and forwards to an insecure backend, while client mode accepts local insecure connections and forwards them to a TLS-secured service. Over time the README grew to document certificate reloads, ACME, PKCS#11, macOS Keychain, Windows Certificate Store, SPIFFE Workload API, Prometheus metrics, systemd and launchd socket activation, and Windows service management.

Adoption history

Ghostunnel's adoption sits in security and operations teams that need a small proxy rather than a full service mesh or general reverse proxy. Official materials point users to GitHub releases and Docker Hub, and the project documents Linux, macOS, Windows, and other Go-supported Unix systems.

How it is used

Practitioners use Ghostunnel to wrap legacy TCP services with mutual TLS, add client-certificate authorization, run local TLS clients for remote services, reload short-lived certificates, expose metrics, and deploy the proxy under a service manager.

Why package nerds care

Package nerds care about Ghostunnel because it packages a focused security boundary as one executable: install it, provide certificates, and put mTLS in front of a service without rewriting the application.
