A PHP library for generating random strings using Crockford Base32 encoding alphabet.

Features
--------

[](#features)

- Generates cryptographically secure random strings using PHP 8.3+'s `Random\Randomizer`
- Uses Crockford Base32 alphabet: `0123456789ABCDEFGHJKMNPQRSTVWXYZ`
- Excludes ambiguous characters (I, L, O, U) for better readability
- Type-safe with strict typing enabled
- Comprehensive error handling
- Optional `brick/math` dependency for large unique pools (> 1.15 quintillion codes)

Requirements
------------

[](#requirements)

- PHP 8.3 or higher
- `Random\Randomizer` extension (included in PHP 8.3+)

### Optional Dependencies

[](#optional-dependencies)

- `brick/math` (^0.8 || ^0.9 || ^0.10 || ^0.11 || ^0.12) - Required only for `UniqueCrockfordPool` with lengths > 12. For most use cases (pool lengths 1-12, which support up to 1.15 quintillion unique codes), native PHP integers are sufficient.

Installation
------------

[](#installation)

```
composer require checkthiscloud/crockford-random
```
