This package contains an implementation of a high-quality splittable pseudorandom number generator. 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.

proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
