How To Install ghc-tf-random on CentOS 7
Introduction
In this tutorial we learn how to install ghc-tf-random on CentOS 7.
What is ghc-tf-random
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, Pałka 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 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 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.
We can use yum or dnf to install ghc-tf-random on CentOS 7. In this tutorial we discuss both methods but you only need to choose one of method to install ghc-tf-random.
Install ghc-tf-random on CentOS 7 Using yum
Update yum database with yum using the following command.
sudo yum makecache
After updating yum database, We can install ghc-tf-random using yum by running the following command:
sudo yum -y install ghc-tf-random
Install ghc-tf-random on CentOS 7 Using dnf
If you don’t have dnf installed you can install DNF on CentOS 7 first.
Update yum database with dnf using the following command.
sudo dnf makecache
After updating yum database, We can install ghc-tf-random using dnf by running the following command:
sudo dnf -y install ghc-tf-random
How To Uninstall ghc-tf-random on CentOS 7
To uninstall only the ghc-tf-random package we can use the following command:
sudo dnf remove ghc-tf-random
