Linux uses pwgen command to create random passwords

Create random passwords. I have written an article on "php password generation class" before.

The functions of the PHP password generation class are as follows:

1. The password length can be set
2. The number of passwords to be generated can be set and batch generated .
3. You can specify password rules, letters, numbers, special characters, etc.

For non-Linux systems, you can use the above class to create random passwords.
In Linux systems, it is easier to use the pwgen command to create a random password.

Installation:

sudo apt-get install pwgen

Syntax:

pwgen [ OPTION ] [ pw_length ] [ num_pw ]

Parameters:
-c or –capitalize
Password must contain at least one uppercase letter

-A or –no-capitalize
Password Does not contain uppercase letters

-n or –numerals
Password must contain at least one number

-0 or –no-numerals
The password does not contain numbers

-y or –symbols
The password contains at least one special symbol

-s or –secure
Generate a completely random password

-B or –ambiguous
The password does not contain ambiguous characters (such as 1,l,O,0)

-H or –sha1=path/to/file[#seed]
Use SHA1 hash of the given file as a random seed

-C
Print generated passwords in columns

-1
Do not print generated passwords in columns, i.e. one password per line

-v or –no-vowels
Do not use any vowels to avoid accidental swear words

Example:

generates length 8, containing Numbers, 4 passwords containing uppercase and lowercase letters, column printing

pwgen -ncC 8 4IGhoo0Oh Thex7AeS Ir9xaera Ahngi6Ee

Generate 4 passwords of length 8, containing numbers, lowercase letters, no ambiguity, column printing

pwgen -nABC 8 4yaew4aph roof3sho ooyoo3oh soo9coah

Generate 8 passwords of length 16, containing numbers, uppercase and lowercase letters, and special characters, printed in lines

pwgen -ncy1 16 8egh5iehoo7Keiqu/ooC8quaiteof+een
