PHP library for simple secure random string generation (e.g. - passwords / salts)
Created by Chris Kankiewicz (@PHLAK)

---

Requirements

• PHP >= 7.2

Install with Composer

composer require phlak/strgen

Usage

// Import StrGen
use PHLAK\StrGen;

// Initialize the Generator
$generator = new StrGen\Generator();

// Generate a random string of characters
$generator->length(16)->generate(); // Returns something like '8a*Ag@I0*s0v[S3u'

Character Sets

StrGen has a few built-in character sets available for ease of use. You can specify which set(s) to use by passing a character set or an array of sets to the charset() method.

Example using built-in sets:

$generator = new StrGen\Generator();

$generator->charset(StrGen\CharSet::ALPHA_NUMERIC)->generate();

// or

$generator->charset([StrGen\CharSet::MIXED_ALPHA, StrGen\CharSet::NUMERIC])->generate();

Available presets:

Key	Character Set
StrGen\CharSet::LOWER_ALPHA	abcdefghijklmnopqrstuvwxyz
StrGen\CharSet::UPPER_ALPHA	ABCDEFGHIJKLMNOPQRSTUVWXYZ
StrGen\CharSet::MIXED_ALPHA	abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ
StrGen\CharSet::NUMERIC	0123456789
StrGen\CharSet::ALPHA_NUMERIC	abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ 0123456789
StrGen\CharSet::SPECIAL	!@#$%^&*()-_=+.?{}[]<>:;/\|~
StrGen\CharSet::ALL	abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ 0123456789 !@#$%^&*()-_=+.?{}[]<>:;/\|~

Custom sets:

You can also manually define a character set by passing a string of characters to the charset() method.

$generator = new StrGen\Generator();

$generator->charset('0123456789abcdef')->generate();

Convenience Functions

StrGen also has built-in convenience functions for generating strings from the included character sets or a custom character set.

$generator->lowerAlpha($length);
$generator->upperAlpha($length);
$generator->mixedAlpha($length);
$generator->numeric($length);
$generator->alphaNumeric($length);
$generator->special($length);
$generator->all($length);
$generator->custom($length, $charset);
