The billstclair/elm-dev-random package provides cryptographically secure random number generation via JavaScript's window.crypto.getRandomValues() function.
As of version 2.0.0, the PortFunnel.DevRandom module uses billstclair/elm-port-funnel to share a pair of ports with other port modules. This implies a fairly major change to clients.
If you want to continue to use the earlier DevRandom port setup, use version 1.1.6 for Elm 0.19 or 1.1.5 for Elm 0.18.
The PortFunnel.DevRandom module contains a pure Elm API, using the standard Elm Random module. If you follow the directions in the README for the example directory, you can use the getRandomValue() mechanism instead.
The package name is a reflection of /dev/random, the OS-provided cryptographically-secure random number generator for Unix-like systems (e.g. Linux and MacOS).
