With$RANDOM,we get anumber between0and32767. However, in this case, we need tolimit the random valuesbetween1and6, so we can use the modulo (%) operator to limit the values betweenmin=1andmax=6: $ cat dice.sh #!/bin/bash function roll_dice { min=1 max=6 number=$(expr $min ...

Bash script and iterate through a possible number of characters. For this, we’ll first create a variable consisting of a set of characters. Next, we’ll use the parameter expansion along with the modulo operator. For instance, to generate the random characters with the charactersabcd1234ABCD:...
C# Random class returns apseudo-random numbergenerator, which is an algorithm that produces a sequence of numbers that meet certain statistical requirements for randomness. TheNext() methodin Random class returns a non-negativerandom number. We can limit the generation of Random number by giving a...
Our bash one-liner to generate (pseudo)random passwords Conclusion Congratulations you have your own one-liner for a password generator that is completely customizable. You can use whatever set of characters you want in your password and do not have to depend upon human guesswork to create a sa...
WARNING: The passwords generated using this option are not very random. If you use this option, make sure the attacker can not obtain a copy of the file. Also, note that the name of the file may be easily available from the ~/.history or ~/.bash_history file. -h, --help Print...
gpg --gen-random --armor 1 14 Of course, there are many other ways to generate a strong password. For example, you can add the following bash shell function to your~/.bashrcfile: genpasswd() { strings /dev/urandom | grep -o '[[:alnum:]]' | head -n 14 | tr -d '\n'; echo...
The shell variable$RANDOMin the Bash shell provides access to the built-in random number generator. However, this randomization is not strong enough for cryptography and should be used as a last resort. $ echo $RANDOM3327 For the majority of applications, the Linux kernel’s/dev/urandompseudo...
In this article, we will share interesting command-line tools to generate random passwords and also how to encrypt and decrypt passwords using the slat method.
"ndmansfield" is a simple program which generates random self-avoiding space-filling curves (also called "lattice Hamiltonian paths") in an arbitrary number of dimensions using the algorithm developed by Marc L. Mansfield: (Mansfield, M.L., J. Chem Phys, 2006, 125(15):154103) The program ...
