About:
Ghostunnel is a simple TLS proxy that secures TCP connections with mutual TLS authentication. It listens on a port and forwards traffic to one or more backend servers, terminating TLS at the edge. This is useful for adding encryption and authentication to non-TLS services or protecting internal traffic.
|
Key Features:
- Terminates TLS to secure plain TCP connections
- Supports mutual TLS (mTLS) for client and server authentication
- Flexible routing to single or multiple backends
- Lightweight Go implementation with minimal dependencies
|
Use Cases:
- Securing database connections (e.g., PostgreSQL, Redis) over untrusted networks
- Adding TLS to legacy or non-TLS services without modifying application code
- Implementing mTLS-based access control for internal services
|
Alternatives:
-
stunnel
– Ghostunnel is a modern Go alternative with native TLS and mTLS support; stunnel is older and config-based
-
haproxy
– HAProxy is a full-featured load balancer; Ghostunnel focuses on simple TLS termination and forwarding
