The Keygen plugin is a key or serial generator based on user-defined mask patterns. The plugin is able to generate keys like the example below:

6W2F-4RJB-KV0Z-ADA6-4SJ2

It can be used to generate keys for several purposes, some examples are:

• Unique links to reset passwords
• Registration via invitation link
• Two-Factor authentication codes
• File sharing links
• Product redemption keys
• Discount coupons
• Referral codes

Installation

Fisrt, run the following command in your project:

composer require kaiopiola/keygen

Then, call the main class on the PHP file you want to load it:

use Kaiopiola\Keygen\Key;

How Keygen works

How to create a new key

To create a new key, just instantiate the class in a variable, and then define its configuration parameters, as shown in the example below:

# Instantiating class in a variable:
$exampleKey = new Key;

# Setting parameters:
$exampleKey->setPattern("XXXX-NNNN-LLLL"); // Defines the pattern that the code will use to define its new key. 
// The letters represent the type of content that can be used in that space, as per the rule:
// X - Any letter or number
// N - Numbers only as defined
// L - Letters only as defined
// Any other characters like dashes, dots, slashes, and even other letters and numbers, will not be replaced.
// If this property is not defined, the following will be used by default: XXXXX-XXXXX-XXXXX

$exampleKey->setNumbers("789"); // Defines the numbers that can compose your key, if not defined, it will use by default "0123456789"
$exampleKey->setLetters("ABC"); // Defines the letters that can compose your key, if not defined, it will use by default "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

$exampleKey->generate(); // Generate your key and return a string value with the result

How to create a new unique key

You also have the option to generate an unique key to avoid duplicates, using the example below:

$exampleKey->setExistingKeys([]); // Defines the existing keys that the code will avoid duplicates. Must be type array.

$exampleKey->generateUnique(); // Generate your key and return a string value with the result

This is also compatible with setPattern, setNumbers and setLetters too!
