Simple library for generating random passwords.
- PHP >= 8.0
- ext-mbstring
Install Composer
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
Now tell composer to download the library by running the command:
$ composer require hackzilla/password-generator
Composer will add the library to your composer.json file and install it into your project's vendor/hackzilla directory.
use Hackzilla\PasswordGenerator\Generator\ComputerPasswordGenerator; $generator = new ComputerPasswordGenerator(); $generator ->setOptionValue(ComputerPasswordGenerator::OPTION_UPPER_CASE, true) ->setOptionValue(ComputerPasswordGenerator::OPTION_LOWER_CASE, true) ->setOptionValue(ComputerPasswordGenerator::OPTION_NUMBERS, true) ->setOptionValue(ComputerPasswordGenerator::OPTION_SYMBOLS, false) ; $password = $generator->generatePassword();
If you want to generate 10 passwords that are 12 characters long.
use Hackzilla\PasswordGenerator\Generator\ComputerPasswordGenerator; $generator = new ComputerPasswordGenerator(); $generator ->setUppercase() ->setLowercase() ->setNumbers() ->setSymbols(false) ->setLength(12); $password = $generator->generatePasswords(10);
use Hackzilla\PasswordGenerator\Generator\HybridPasswordGenerator; $generator = new HybridPasswordGenerator(); $generator ->setUppercase() ->setLowercase() ->setNumbers() ->setSymbols(false) ->setSegmentLength(3) ->setSegmentCount(4) ->setSegmentSeparator('-'); $password = $generator->generatePasswords(10);
If you can think of a better name for this password generator then let me know.
The segment separator will be remove from the possible characters.
use Hackzilla\PasswordGenerator\Generator\HumanPasswordGenerator; $generator = new HumanPasswordGenerator(); $generator ->setWordList('/usr/share/dict/words') ->setWordCount(3) ->setWordSeparator('-'); $password = $generator->generatePasswords(10);
use Hackzilla\PasswordGenerator\Generator\RequirementPasswordGenerator; $generator = new RequirementPasswordGenerator(); $generator ->setLength(16) ->setOptionValue(RequirementPasswordGenerator::OPTION_UPPER_CASE, true) ->setOptionValue(RequirementPasswordGenerator::OPTION_LOWER_CASE, true) ->setOptionValue(RequirementPasswordGenerator::OPTION_NUMBERS, true) ->setOptionValue(RequirementPasswordGenerator::OPTION_SYMBOLS, true) ->setMinimumCount(RequirementPasswordGenerator::OPTION_UPPER_CASE, 2) ->setMinimumCount(RequirementPasswordGenerator::OPTION_LOWER_CASE, 2) ->setMinimumCount(RequirementPasswordGenerator::OPTION_NUMBERS, 2) ->setMinimumCount(RequirementPasswordGenerator::OPTION_SYMBOLS, 2) ->setMaximumCount(RequirementPasswordGenerator::OPTION_UPPER_CASE, 8) ->setMaximumCount(RequirementPasswordGenerator::OPTION_LOWER_CASE, 8) ->setMaximumCount(RequirementPasswordGenerator::OPTION_NUMBERS, 8) ->setMaximumCount(RequirementPasswordGenerator::OPTION_SYMBOLS, 8) ; $password = $generator->generatePassword();
A limit can be removed by passing null
$generator ->setMinimumCount(RequirementPasswordGenerator::OPTION_UPPER_CASE, null) ->setMaximumCount(RequirementPasswordGenerator::OPTION_UPPER_CASE, null) ;
When setting the minimum and maximum values, be careful of unachievable settings.
For example the following will end up in an infinite loop.
$generator ->setLength(4) ->setOptionValue(RequirementPasswordGenerator::OPTION_UPPER_CASE, true) ->setOptionValue(RequirementPasswordGenerator::OPTION_LOWER_CASE, false) ->setMinimumCount(RequirementPasswordGenerator::OPTION_UPPER_CASE, 5) ->setMaximumCount(RequirementPasswordGenerator::OPTION_LOWER_CASE, 1) ;
For the moment you can call $generator->validLimits() to test whether the counts will cause problems.
If the method returns true, then you can proceed. If false, then generatePassword() will likely cause an infinite loop.

Since version 1.5.0, the library depends on the presence of random_int which is found in PHP 7.0+
