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):

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