How To Install rng-tools-debian on Kali Linux
Introduction
In this tutorial we learn how to install rng-tools-debian
on Kali Linux.
What is rng-tools-debian
rng-tools-debian is:
The rngd daemon acts as a bridge between a Hardware RNG (random number generator), such as the ones in some Intel/AMD/VIA chipsets, and the kernel??s PRNG (pseudo-random number generator).
It tests the data received from the HWRNG using the FIPS 140-2 (2002-10-10) tests to verify that it is indeed random then feeds the random data to the kernel entropy pool.
This increases the bandwidth of the /dev/random device, from a source that does not depend on outside activity. It may also improve the quality (entropy) of the randomness of /dev/random.
An HWRNG kernel module such as hw_random, or some other source of true entropy that is accessible as a device or fifo, is required to use this package. Securely tunneling entropy over the network and feeding it to rngd is also possible.
This is an unofficial version of rng-tools (as classically shipped by Debian up to and including release 10 ??buster??), version 2, extensively modified to add multithreading and a lot of new functionality. However, most users of newer or high-bandwidth HWRNGs might wish to install the latest version of upstream rng-tools (packaged as rng-tools5) instead; that package offers more performant support for those, even if it lacks the new functionality from this version.
