name: entropy version: 0.4.1.10 description: A mostly platform independent 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: Custom -- ^^ Test for RDRAND support using 'ghc' cabal-version: >=1.10 tested-with: GHC == 8.2.2 -- data-files: extra-source-files: ./cbits/getrandom.c ./cbits/random_initialized.c ./cbits/rdrand.c, ./cbits/rdrand.h, README.md Flag DoNotGetEntropy Description: Avoid use of the getentropy() *nix function. By default getentropy will be used if detected during compilation (this plays poorly with cross compilation).
