Portier Relying Party Demo

This is a minimal Python implementation of a Portier Relying Party. To get started, you need Python 3.4 or newer.

python3 -m venv ./venv
./venv/bin/pip install -r requirements.txt
./venv/bin/python3 ./


By default, this demo listens on http://localhost:8000 and delegates to the production Portier Broker at This should be sufficient for local development and testing of this demo.

To override these values, you can either modify the config.ini file (there is an example in config.ini.dist), or set environment variables.

Environment variables always take precedence over config.ini.

config.ini Environment Variable Default Value
ListenPort DEMO_LISTEN_PORT 8000
WebsiteURL DEMO_WEBSITE_URL http://localhost:8000
RedisURL DEMO_REDIS_URL (none - uses FakeRedis)
Secret DEMO_SECRET (none - generates one)

About Redis

To prevent replay attacks, this demo needs to be able to store and retrieve a nonce for each login attempt. Redis is a great choice for this, since all its operations are atomic and it supports time-based expiration of data.

For production deployments of this demo, you must provide a Redis server via the RedisURL setting. For local testing, this demo uses FakeRedis.

Deploying on Heroku

In addition to the environment variables above, this demo will attempt to detect available metadata when deployed on Heroku.

If $PORT is set, the app will bind to${PORT} by default. This can be overriden by setting the DEMO_LISTEN_IP and DEMO_LISTEN_PORT environment variables.

If Dyno Metadata is enabled for your application, the WebsiteURL will default to the hostname https://${HEROKU_APP_NAME} This can still be overridden by setting the DEMO_WEBSITE_URL environment variable.

If you are using Redis To Go, RedisGreen, RedisCloud, Heroku Redis, or openredis with your deployment, this demo will automatically detect and default the first provider it finds from that list. This can still be overridden by setting the DEMO_REDIS_URL environment variable.
