The generator is based on a cryptographic hash\nfunction built on top of the ThreeFish block cipher. See the paper Splittable\nPseudorandom Number Generators Using Cryptographic Hashing by Claessen,\nPalka for details and the rationale of the design.\n\nThe package provides the following:\n\n  A splittable PRNG that implements the standard System.Random.RandomGen class.\n\n  The generator also implements an alternative version of the\n  System.Random.TF.Gen.RandomGen class (exported from System.Random.TF.Gen),\n  which requires the generator to return pseudorandom integers from the full\n  32-bit range, and contains an n-way split function.\n\n  An alternative version of the Random class is provided, which is linked to the\n  new RandomGen class, together with Random instances for some integral types.\n\n  Two functions for initialising the generator with a non-deterministic seed:\n  one using the system time, and one using the /dev/urandom UNIX special file.\n\nThe package uses an adapted version of the reference C implementation of\nThreeFish from the reference package of the Skein hash function\n(https://www.schneier.com/skein.html), originally written by Doug Whiting.","flavors":[],"html":"https://daemonports.org/netbsd/devel/hs-tf-random/","kind":"port","lastUpdate":null,"license":["modified-bsd"],"maintainer":"szptvlfn@NetBSD.org","name":"hs-tf-random","newest":false,"newestVersion":null,"noVulnData":false,"origin":"devel/hs-tf-random","otherSystems":[],"packages":[{"repo":"NetBSD 10.1 x86_64","versions":["0.5nb15"]},{"repo":"NetBSD 10.1 aarch64","versions":["0.5nb15"]},{"repo":"SmartOS / illumos x86_64","versions":["0.5nb15"]},{"repo":"macOS 15 arm64","versions":["0.5nb15"]}],"pkgName":"hs-tf-random-0.5nb15","related":null,"repository":"pkgsrc","requiredBy":[],"requiredByCount":0,"runDepends":["devel/hs-primitive","devel/hs-random","lang/ghc98"],"status":null,"system":"netbsd","systemLabel":"NetBSD","version":"0.5nb15","versions":null,"vulnerabilities":null,"www":"http://hackage.haskell.org/package/tf-random"}
