Custom Password Generator

A lightweight, customizable password generator by Escuelait. Ideal for generating secure, random passwords with optional symbol inclusion.

Installation

Install via Composer:

composer require escuelait/custom-password-generator

Quick Usage

use Escuelait\CustomPasswordGenerator\PasswordGenerator;

$generator = new PasswordGenerator();

// Generate a 12-character password with 2 symbols (default settings)
$password = $generator->generate();

echo $password; // Example: @k1Zq9&Lm08A

Configuration

You can customize both the total password length and the number of symbols:

$password = (new PasswordGenerator())
    ->length(16)   // Total length of the password
    ->symbols(4)   // Number of symbols to include
    ->generate();

echo $password; // Example: %aB3#XgF1$Ld9&kM

⚠️ If the number of symbols exceeds the total password length, an InvalidArgumentException will be thrown.

How It Works

• Character sets used:

  • Letters: a-z, A-Z
  • Numbers: 0-9
  • Symbols: !@#$%&*()_+-=[]{}|;:,.<>?

• Defaults:

  • Length: 12
  • Symbols: 2

• Fluent methods:

  • length(int $length) — Set total password length.
  • symbols(int $symbols) — Set number of symbols.

Example

use Escuelait\CustomPasswordGenerator\PasswordGenerator;

$password = (new PasswordGenerator())
    ->length(20)
    ->symbols(5)
    ->generate();

echo $password;

❗ Exceptions

If the number of requested symbols exceeds the total length:

InvalidArgumentException: The number of symbols cannot exceed the total password length
