How To Install jitterentropy-rngd on Debian 12
Introduction
In this tutorial we learn how to install jitterentropy-rngd on Debian 12.
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 Debian 12. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
