The generator is based on a cryptographic hash function built on top of the ThreeFish block cipher. See the paper /Splittable Pseudorandom Number Generators Using Cryptographic Hashing/ by Claessen, PaBka for details and the rationale of the design. + + The package provides the following: + + * A splittable PRNG that implements the standard 'System.Random.RandomGen' class. + + * The generator also implements an alternative version of the 'System.Random.TF.Gen.RandomGen' class (exported from "System.Random.TF.Gen"), which requires the generator to return pseudorandom integers from the full 32-bit range, and contains an n-way split function. + + * An alternative version of the @Random@ class is provided, which is linked to the new @RandomGen@ class, together with @Random@ instances for some integral types. + + * Two functions for initialising the generator with a non-deterministic seed: one using the system time, and one using the @\/dev\/urandom@ UNIX special file. + + The package uses an adapted version of the reference C implementation of ThreeFish from the reference package of the Skein hash function (<https://www.schneier.com/skein.html>), originally written by Doug Whiting. + + Please note that even though the generator provides very high-quality pseudorandom numbers, it has not been designed with cryptographic applications in mind. + </longdescription> +</pkgmetadata> |
