The entropy package

[Tags:bsd3, library]

A platform independent method to obtain cryptographically strong entropy (RDRAND when available anywhere, urandom on nix, CryptAPI on Windows, patches welcome) Users looking for cryptographically strong (number-theoretically sound) PRNGs should see the DRBG package too.

Readme for entropy

Readme for entropy-0.3.7


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.
