The package exposes a lightweight invokable validation rule that checks whether a value is numeric, has the expected 13-digit length, contains a valid encoded birth date, and matches the official CNP checksum. It works independently of the Enso ecosystem and can be used in any Laravel application that relies on Laravel's validator. Installation ------------ [](#installation) Install the package: ``` composer require laravel-enso/cnp-validator ``` No additional service provider registration is required. Features -------- [](#features) - Provides an invokable Laravel validation rule through `LaravelEnso\CnpValidator\Validators\Cnp`. - Validates that the CNP contains only numeric digits. - Validates the required 13-character length. - Validates the encoded date portion of the CNP. - Validates the checksum using the official control hash table. - Exposes a reusable low-level validator helper through `LaravelEnso\CnpValidator\Validators\Validator`. Usage ----- [](#usage) Use the rule in a form request or validator instance: ``` use Illuminate\Support\Facades\Validator; use LaravelEnso\CnpValidator\Validators\Cnp; $validator = Validator::make( ['cnp' => '1800219081826'], ['cnp' => ['nullable', new Cnp()]], ); ``` Example in a form request: ``` use Illuminate\Validation\Rule; use LaravelEnso\CnpValidator\Validators\Cnp; public function rules(): array { return [ 'cnp' => [ 'nullable', 'max:13', new Cnp(), Rule::unique('users', 'nin'), ], ]; } ``` ::: warning Note The package reports failed validation with the `Invalid` message. If you want a localized or more specific validation message, map that message in your validation language files or customize it in the consuming validator layer. ::: API --- [](#api) ### Validation Rule [](#validation-rule) `LaravelEnso\CnpValidator\Validators\Cnp` Public entry point: - `__invoke($attribute, $value, $fail)` The rule calls the internal validator and fails the field when the provided CNP is invalid. ### Validator Helper [](#validator-helper) `LaravelEnso\CnpValidator\Validators\Validator` Public methods: - `__construct(?string $cnp = null)` - `fails(string $cnp): bool` - `passes(): bool` Validation flow: - numeric-only check - 13-digit length check - encoded date validation - checksum validation Depends On ---------- [](#depends-on) Framework dependency: - [`laravel/framework`](https://github.com/laravel/framework) [↗](https://github.com/laravel/framework) Contributions ------------- [](#contributions) are welcome. Pull requests are great, but issues are good too. Thank you to all the people who already contributed to Enso! ### Health Score 58 — FairBetter than 98% of packages Maintenance86 Actively maintained with recent releases Popularity29 Limited adoption so far Community17 Small or concentrated contributor base Maturity85 Battle-tested with a long release history Bus Factor1 Top contributor holds 70.9% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
