Componenta Identity
===================

[](#componenta-identity)

UUID value objects and generators for domain identities.

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

[](#installation)

```
composer require componenta/identity
```

The package declares `Componenta\Identity\ConfigProvider` in `extra.componenta.config-providers`. When `componenta/composer-plugin` is installed, the provider is added to the generated provider list automatically.

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

[](#requirements)

- PHP 8.4+
- 64-bit PHP runtime for `UuidFactory`

Related Packages
----------------

[](#related-packages)

PackageWhy it matters here`componenta/policy`Uses `IdentityInterface` for actors and owned resources.`componenta/cqrs``Operation` uses UUIDs as operation identifiers.`componenta/di`Registers `UuidFactoryInterface` through `ConfigProvider`.`componenta/uuid`Legacy Ramsey compatibility; new domain code should prefer this package.What It Provides
----------------

[](#what-it-provides)

- `UuidInterface`: minimal identity contract with string conversion and equality.
- `RfcUuidInterface`: UUID contract with `bytes`, `version`, and `variant` properties.
- `Uuid`: immutable RFC UUID value object backed by 16 raw bytes.
- `UuidFactoryInterface`: generation/from-bytes contract.
- `UuidFactory`: UUID v1, v3, v4, v5, v6, v7, and v8 generator.
- `UuidNamespace`: standard namespaces for name-based UUIDs.

UUID Value Object
-----------------

[](#uuid-value-object)

```
use Componenta\Identity\Uuid;

$uuid = Uuid::fromString('018f6d5d-3f7a-7a9b-8c2f-123456789abc');

$uuid->toString(); // 018f6d5d-3f7a-7a9b-8c2f-123456789abc
$uuid->bytes;      // 16-byte binary representation
$uuid->version;    // 7
$uuid->variant;    // UuidVariant::Rfc
```

`Uuid::fromString()` accepts uppercase input and normalizes output to lowercase canonical form.

Equality
--------

[](#equality)

```
$left = Uuid::fromString($id);
$right = Uuid::fromBytes($left->bytes);

$left->equals($right); // true
```

Domain code should usually depend on `UuidInterface`. Infrastructure that needs raw bytes or version inspection can depend on `RfcUuidInterface`.

UUID Factory
------------

[](#uuid-factory)

```
use Componenta\Identity\UuidFactory;
use Componenta\Identity\UuidGenerationVersion;
use Componenta\Identity\UuidNamespace;

$factory = new UuidFactory(UuidGenerationVersion::V7);

$id = $factory->generate();              // default version
$random = $factory->v4();                // random UUID
$ordered = $factory->v7();               // Unix timestamp UUID
$nameBased = $factory->v5(UuidNamespace::Dns, 'example.com');
```

Name-based UUIDs are deterministic for the same namespace and name.

DI Registration
---------------

[](#di-registration)

`ConfigProvider` registers `UuidFactoryInterface` as a factory returning `UuidFactory`.
