Here is a tutorial to learn how to install rng tools using apt-get command. Step 1: Open terminal with su access and enter the command as shown below: apt-get install rng tools -y Step 2: After completion, the install command exits and instructs the user to restart the running instances of rng tools if it is running already.
The difference between /dev/random and /dev/urandom is that the former is a blocking device, which means it stops supplying numbers when it determines that the amount of entropy is insufficient for generating a properly random output. Conversely, /dev/urandom is a non-blocking source, which reuses the kernel's entropy pool and is thus able to provide an unlimited supply of pseudo-random numbers, albeit with less entropy. As such, /dev/urandom should not be used for creating long-term cryptographic keys. The rng-tools package also contains the rngtest utility, which can be used to check the randomness of data. To test the level of randomness of the output of /dev/random, use the rngtest tool as follows: $ cat /dev/random rngtest -c 1000 rngtest 2 Copyright (c) 2004 by Henrique de Moraes Holschuh This is free software; see the source for copying conditions.
