This package provides an asyncio-driven library that interfaces with the Websocket API provided by Blue Current. This was made for the Blue Current Home Assistant integration.

This library implements the basic OPRF (ristretto255, SHA-512) variant from the "Oblivious Pseudorandom Functions using Prime-Order Groups" Draft from the IRTF Crypto Forum Research Group (https://github.com/cfrg/draft-irtf-cfrg-voprf/). Additionally it implements a threshold OPRF based on "TOPPSS: Cost-minimal Password-Protected Secret Sharing based on Threshold OPRF" by Krawczyk et al (https://ia.cr/2017/363).

pg_cron is a simple cron-based job scheduler for PostgreSQL (9.5 or higher) that runs inside the database as an extension. It uses the same syntax as regular cron, but it allows you to schedule PostgreSQL commands directly from the database. pg_cron can run multiple jobs in parallel, but it runs at most one instance of a job at a time. If a second run is supposed to start before the first one finishes, then the second run is queued and started as soon as the first run completes.

This extension is for anyone with Logical Replication Slots on Postgres databases that are also part of a Physical Streaming Replication architecture.
