pollen

Pollen is a high-performance, scalable, free web server that provides 'Entropy-as-a-Service' by offering small strings of entropy over both HTTPS and clear-text HTTP connections.
Canonical provides a Pollen server as a service to the Ubuntu community at https://entropy.ubuntu.com. Beginning with Ubuntu 14.04, Ubuntu cloud images include the Pollinate client, which will try (for up to 3 seconds at first boot) to seed the PRNG with input from https://entropy.ubuntu.com.
This snap package is specifically designed to work with the Pollen charm in order to provide easy and seamless deployment within a juju-managed environment. This snapped pollen includes additional support for Prometheus metrics to integrate with Canonical Observability Stack.
