# Deploying the server

> A self-hosted service that handles Privacy Pass cryptography on your behalf.

The Relay Gateway Service is a self-hosted microservice that wraps the Relay Server SDK. It exposes a simple HTTP API so your server can complete the Relay flow without directly implementing Privacy Pass cryptography.

This is useful when:

* Your stack does not have library support for blind RSA cryptography or OHTTP
* You want to isolate cryptographic operations into a dedicated service

The gateway handles the full blind/unblind protocol internally. Your server only needs to make standard HTTP calls.

## Deployment

The gateway is distributed as a Docker image hosted on GitHub Container Registry (GHCR):

```bash
docker pull ghcr.io/persona-id/persona-relay-gateway:latest
```

## Configuration

The gateway takes no configuration — there are no environment variables to set and no API key to provision. It is a stateless HTTP wrapper: every call carries its own credentials, and the environment is chosen per request. See [Usage](/relay-gateway-service-usage).
