They are referred to as 'pronounceable' because the passwords may actually be pronounced like regular words. A good thing is Apg will generate 'pronounceable' passwords.

How to Generate Enough ‘Entropy’ For GPG Key Generation ProcessĪpg (stands for Automatic Password Generator) is a command line utility for generating strong random passwords.

An Easy Way To Encrypt And Decrypt Files From Commandline In Linux.

This command will generate a secure, random, strong and base64 encoded password. To generate a random and strong password with length of 14 characters using GPG, run the following command from the Terminal: $ gpg -gen-random -armor 1 14

GPG (GnuPG or GNU Privacy Guard), is free command-line program and replacement of Symantec's PGP cryptographic software.

v or -no-vowels (Do not use any vowels so as to avoid accidental nasty words)įor more details, check the man pages. 1 (Don't print the generated passwords in columns) C (Print the generated passwords in columns)

H or -sha1=path/to/file (Use sha1 hash of given file as a (not so) random generator) B or -ambiguous (Don't include ambiguous characters in the password) s or -secure (Generate completely random passwords) y or -symbols (Include at least one special symbol in the password) 0 or -no-numerals (Don't include numbers in the password) n or -numerals (Include at least one number in the password) A or -no-capitalize (Don't include capital letters in the password) c or -capitalize (Include at least one capital letter in the password) There are also some useful options available to use with pwgen command. To include at least 1 number in the password run: $ pwgen 14 1 -n 1 Generate 100 random strings with 14 characters long using pwgen Sample output: Ho8phaedohxoo3 em1HaefohYi8gu To generate 2 different passwords with length of 14 characters, run: $ pwgen 14 2 The above command will generate only one password with length of 14 characters. Once pwgen installed, generate a random and strong password with length of 14 letters using command: $ pwgen 14 1 In Arch based systems: $ sudo pacman -S pwgen

In RPM based systems: $ sudo yum install pwgen To install pwgen in DEB based systems, run: $ sudo apt install pwgen It designs secure passwords that can be easily memorized by humans. It is available in the most Unix-like operating systems. Pwgen is simple, yet useful command line utility to generate a random and strong password in seconds. $ man openssl $ man base64 $ man wc Method 2 - Using Pwgen

To generate generate a 16 byte (128 bit) random value, the command would be: $ openssl rand -base64 16įor more details, refer the man pages. The -d and -c flags in the above command refers 'decode' and 'byte count' respectively. You can count the number of characters in the above random value by decoding it using command: $ echo 'B3ch3m3e35LcCiRQiqI=' | base64 -d | wc -cĪs you can see, we have generated a random and strong password with 14 characters long. The above command will generate a 14 byte random value encoded with base64. Generate a strong password in Linux using OpenSSL
