Introduction

This package allows Haskell users to easily acquire entropy for use in critical security applications by calling out to either windows crypto api, unix/linux’s /dev/urandom, or the RDRAND instruction.

This package supports Windows, {li,u}nix, QNX, and has preliminary support for HaLVM.
