[](#uuid)

Light lib to generate an universally unique identifier V4

Get started
===========

[](#get-started)

- `composer install appkweb/uuid`
- ```
    public function __construct(
          private readonly UuidService $uuidService,
      )
      {
      }

      /**
       * @return void
       * @throws Exception
       */
      public function __invoke():void
      {
          echo "{$this->uuidService->generate()}\n";
      }

    ```

Sources of Entropy
==================

[](#sources-of-entropy)

- Generates 16 random bytes with high entropy, which is excellent for value diversity.
- Provides a timestamp in milliseconds, adding a time dimension.
- Includes the process ID, which varies between processes but is stable during the execution of a specific process.
- Generates an additional random number, adding even more diversity.
- Generates a unique identifier based on the current time and a random number, used in the hash to add additional entropy.
