How To Install jitterentropy-rngd on Kali Linux
Introduction
In this tutorial we learn how to install jitterentropy-rngd on Kali Linux.
What is jitterentropy-rngd
jitterentropy-rngd is:
Using the Jitter RNG core, the rngd provides an entropy source that feeds into the Linux /dev/random device if its entropy runs low. It updates the /dev/random entropy estimator such that the newly provided entropy unblocks /dev/random.
The seeding of /dev/random also ensures that /dev/urandom benefits from entropy. Especially during boot time, when the entropy of Linux is low, the Jitter RNGd provides a source of sufficient entropy.
There are three methods to install jitterentropy-rngd on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install jitterentropy-rngd Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get updateAfter updating apt database, We can install jitterentropy-rngd using apt-get by running the following command:
sudo apt-get -y install jitterentropy-rngdInstall jitterentropy-rngd Using apt
Update apt database with apt using the following command.
sudo apt updateAfter updating apt database, We can install jitterentropy-rngd using apt by running the following command:
sudo apt -y install jitterentropy-rngdInstall jitterentropy-rngd Using aptitude
If you want to follow this method, you might need to install aptitude on Kali Linux first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.
sudo aptitude updateAfter updating apt database, We can install jitterentropy-rngd using aptitude by running the following command:
sudo aptitude -y install jitterentropy-rngdHow To Uninstall jitterentropy-rngd on Kali Linux
To uninstall only the jitterentropy-rngd package we can use the following command:
sudo apt-get remove jitterentropy-rngdUninstall jitterentropy-rngd And Its Dependencies
To uninstall jitterentropy-rngd and its dependencies that are no longer needed by Kali Linux, we can use the command below:
sudo apt-get -y autoremove jitterentropy-rngdRemove jitterentropy-rngd Configurations and Data
To remove jitterentropy-rngd configuration and data from Kali Linux we can use the following command:
sudo apt-get -y purge jitterentropy-rngdRemove jitterentropy-rngd configuration, data, and all of its dependencies
We can use the following command to remove jitterentropy-rngd configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge jitterentropy-rngdDependencies
jitterentropy-rngd have the following dependencies:
