  console.log('Security event:', securityEvent);
};

SDKs

Official SDKs are available for:

Python: pip install koreshield-sdk
JavaScript/TypeScript: npm install koreshield-sdk
Go: go get github.com/koreshield/koreshield-go

Versioning

API versioning follows semantic versioning. Breaking changes will increment the major version number.

Current version: v1

Support

For API support and questions:

GitHub Issues
Documentation
We try to bind the requested UDP port; if busy, you’ll get the assigned port (UDP pool defaults 30001-40000).
External UDP packets to the assigned port are forwarded to your local UDP service; your responses are relayed back.

Flags that matter

<port> (positional): local UDP service to forward to.
--remote-port <port> (optional): ask for a specific public port in the UDP pool.

Quick troubleshooting

Port already in use: retry without --remote-port to let KoreShield pick one, or choose another.
No responses (UDP): ensure your local service replies; the CLI relays responses automatically once it receives them.
