name: entropy version: 0.4.1.2 description: A mostly platform independent (not GHCJS) method to obtain cryptographically strong entropy (RDRAND, urandom, CryptAPI, and patches welcome) Users looking for cryptographically strong (number-theoretically sound) PRNGs should see the 'DRBG' package too. synopsis: A platform independent entropy source license: BSD3 license-file: LICENSE copyright: Thomas DuBuisson author: Thomas DuBuisson maintainer: Thomas DuBuisson category: Data, Cryptography homepage: https://github.com/TomMD/entropy bug-reports: https://github.com/TomMD/entropy/issues stability: stable -- build-type: Simple -- ^^ Used for HaLVM build-type: Custom -- ^^ Test for RDRAND support using 'ghc' cabal-version: >=1.10 tested-with: GHC == 8.2.2 -- data-files: extra-source-files: ./cbits/rdrand.c, ./cbits/rdrand.h, README.md -- Notice to compile with HaLVM the above 'build-type' must be changed -- to 'Simple' instead of 'Custom'.
