Few of them are using native Linux commands and others are using third party tools or utilities which can easily be installed on Linux machine. Here we are looking at native commands like `openssl`, [dd][2], `md5sum`, `tr`, `urandom` and third party tools like mkpasswd, randpw, pwgen, spw, gpg, xkcdpass, diceware, revelation, keepaasx, passwordmaker. - -These are actually ways to get some random alphanumeric string which can be utilized as password. Random passwords can be used for new users so that there will be uniqueness no matter how large your user base is. Without any further delay lets jump into those 15 different ways to generate random password in Linux. - -##### Generate password using mkpasswd utility - -`mkpasswd` comes with install of `expect` package on RHEL based systems. On Debian based systems `mkpasswd` comes with package `whois`. Trying to install `mkpasswd` package will results in error - - -No package mkpasswd available. on RHEL system and E: Unable to locate package mkpasswd in Debian based. - -So install their parent packages as mentioned above and you are good to go. - -Run `mkpasswd` to get passwords - -``` -root@kerneltalks# mkpasswd << on RHEL -zt*hGW65c - -root@kerneltalks# mkpas -``` - -Command behaves differently on different systems so work accordingly. There are many switches which can be used to control length etc parameters. You can explore them from man pages. - -##### Generate password using openssl - -Openssl comes in build with almost all the Linux distributions. We can use its random function to get alphanumeric string generated which can be used as password. - -``` -root@kerneltalks # openssl rand -base64 10 -nU9LlHO5nsuUvw== -``` - -Here, we are using `base64` encoding with random function and last digit for argument to `base64` encoding. - -##### Generate password using urandom - -Device file `/dev/urandom` is another source of getting random characters. We are using `tr` function and trimming output to get random string to use as password. - -``` -root@kerneltalks # strings /dev/urandom |tr -dc A-Za-z0-9 | head -c20; echo -UiXtr0NAOSIkqtjK4c0X -``` - -##### dd command to generate password - -We can even use /dev/urandom device along with [dd command ][2]to get string of random characters. - -``` -oot@kerneltalks# dd if=/dev/urandom bs=1 count=15|base64 -w 0 -15+0 records in -15+0 records out -15 bytes (15 B) copied, 5.5484e-05 s, 270 kB/s -QMsbe2XbrqAc2NmXp8D0 -``` - -We need to pass output through `base64` encoding to make it human readable.

Clean command will be - - -``` -oot@kerneltalks # dd if=/dev/urandom bs=1 count=15 2>/dev/null|base64 -w 0 -F8c3a4joS+a3BdPN9C++ -``` - -##### Using md5sum to generate password - -Another way to get array of random characters which can be used as password is to calculate MD5 checksum! s you know checksum value is indeed looks like random characters grouped together we can use it as password. Make sure you use source as something variable so that you get different checksum every time you run command. For example `date` ! [date command][3] always yields changing output. - -``` -root@kerneltalks # date |md5sum -4d8ce5c42073c7e9ca4aeffd3d157102 - -``` - -Here we passed `date` command output to `md5sum` and get the checksum hash! You can use [cut command][4] to get desired length of output. - -##### Generate password using pwgen - -`pwgen` package comes with [repositories like EPEL][5]. `pwgen` is more focused on generating passwords which are pronounceable but not a dictionary word or not in plain English. You may not find it in standard distribution repo. Install the package and run `pwgen` command. Boom ! - -``` -root@kerneltalks # pwgen -thu8Iox7 ahDeeQu8 Eexoh0ai oD8oozie ooPaeD9t meeNeiW2 Eip6ieph Ooh1tiet -cootad7O Gohci0vo wah9Thoh Ohh3Ziur Ao1thoma ojoo6aeW Oochai4v ialaiLo5 -aic2OaDa iexieQu8 Aesoh4Ie Eixou9ph ShiKoh0i uThohth7 taaN3fuu Iege0aeZ -cah3zaiW Eephei0m AhTh8guo xah1Shoo uh8Iengo aifeev4E zoo4ohHa fieDei6c -aorieP7k ahna9AKe uveeX7Hi Ohji5pho AigheV7u Akee9fae aeWeiW4a tiex8Oht -``` -You will be presented with list of passwords at your terminal! What else you want? Ok. You still want to explore, `pwgen` comes with many custom options which can be referred for man page. - -##### Generate password using gpg tool - -GPG is a OpenPGP encryption and signing tool. Mostly gpg tool comes pre-installed (at least it is on my RHEL7). But if not you can look for `gpg` or `gpg2` package and [install][6] it. - -Use below command to generate password from gpg tool. - -``` -root@kerneltalks # gpg --gen-random --armor 1 12 -mL8i+PKZ3IuN6a7a -``` - -Here we are passing generate random byte sequence switch (`--gen-random`) of quality 1 (first argument) with count of 12 (second argument). Switch `--armor` ensures output is `base64` encoded. - -##### Generate password using xkcdpass - -Famous geek humor website [xkcd][7], published a very interesting post about memorable but still complex passwords. You can view it [here][8]. So `xkcdpass` tool took inspiration from this post and did its work! Its a python package and available on python's official website [here][9] - -All installation and usage instructions are mentioned on that page. Here is install steps and outputs from my test RHEL server for your reference. - -``` -root@kerneltalks # wget https://pypi.python.org/packages/b4/d7/3253bd2964390e034cf0bba227db96d94de361454530dc056d8c1c096abc/xkcdpass-1.14.3.tar.gz#md5=5f15d52f1d36207b07391f7a25c7965f ---2018-01-23 19:09:17-- https://pypi.python.org/packages/b4/d7/3253bd2964390e034cf0bba227db96d94de361454530dc056d8c1c096abc/xkcdpass-1.14.3.tar.gz -Resolving pypi.python.org (pypi.python.org)... 151.101.32.223, 2a04:4e42:8::223 -Connecting to pypi.python.org (pypi.python.org)|151.101.32.223|:443... connected. -HTTP request sent, awaiting response... 200 OK -Length: 871848 (851K) [binary/octet-stream] -Saving to: ‘xkcdpass-1.14.3.tar.gz’ - -100%[==============================================================================================================================>] 871,848 --.-K/s in 0.01s - -2018-01-23 19:09:17 (63.9 MB/s) - ‘xkcdpass-1.14.3.tar.gz’ saved [871848/871848] - - -root@kerneltalks #
