Register the plugin in your panel provider: ``` // app/Providers/Filament/AdminPanelProvider.php use Kukux\DigitalSignature\SignaturePlugin; ->plugins([ SignaturePlugin::make() ->navigationGroup('Documents') // optional ->navigationIcon('heroicon-o-pencil-square') // optional ->navigationSort(10), // optional ]) ``` This registers: - **Signatures** — a full admin resource for registering reusable signature images and viewing signature records - **Sign Document** — header actions inside the Signatures resource for signing with a registered signature --- Preparing a Signable Model -------------------------- [](#preparing-a-signable-model) Any model whose PDF can be signed must implement `Signable` and use `HasSignatures`. ``` use Kukux\DigitalSignature\Contracts\Signable; use Kukux\DigitalSignature\Traits\HasSignatures; class Contract extends Model implements Signable { use HasSignatures; public function getSignableTitle(): string { return $this->title; } public function getSignablePdfPath(): string { return $this->pdf_path; } public function getSignableId(): int|string { return $this->id; } } ``` --- Adding the Sign Action to Your Own Resource ------------------------------------------- [](#adding-the-sign-action-to-your-own-resource) First let the signer register a reusable signature from the built-in **Signatures** resource. Then add `SignDocumentAction` to any resource whose model implements `Signable`. ``` use Kukux\DigitalSignature\Filament\Actions\SignDocumentAction; use Kukux\DigitalSignature\Filament\Columns\SignatureColumn; class ContractResource extends Resource { public static function table(Table $table): Table { return $table ->columns([ TextColumn::make('title'), SignatureColumn::make('signature')->thumbSize(80, 32), ]) ->actions([ SignDocumentAction::make() ->stampAt(page: 1, x: 100, y: 650, w: 200, h: 80), ]); } } ``` For controller-driven or custom page flows, see [Ad-hoc Signing](docs/ad-hoc-signing.md). --- Built-in Signatures Admin Resource ---------------------------------- [](#built-in-signatures-admin-resource) When the plugin is registered, a **Signatures** resource appears in the sidebar automatically. Register `SignaturePlugin::make()` on every Filament panel that should use the package. If a panel discovers or registers `SignatureResource` without the plugin, Filament can report `Plugin [signature] is not registered for panel [admin]`. **List page** — table of all signature records with thumbnail, signer, status, and method. **View page** — full infolist showing the large signature image, signer details, security metadata. Both pages include a **Sign Document** header action. Customize appearance: ``` SignaturePlugin::make() ->navigationGroup('Documents') ->navigationIcon('heroicon-o-pencil-square') ->navigationSort(10) ->navigationLabel('Document Signatures') // Disable the resource entirely (bring your own): SignaturePlugin::make()->withoutResource() ``` --- Security Highlights ------------------- [](#security-highlights) FeatureDefaultPKCS#7 cryptographic signature embedded in PDFAlways onDocMDP P=2 — post-signing modification detectionAlways onHMAC-signed PNG metadata (tEXt + XMP)Always onXMP metadata visible in macOS Preview & Windows ExplorerAlways onSigner identity (name + email) embedded in PNGAlways onForgery / screenshot upload rejectionAlways onDocument integrity hashes (before + after)Always onMachine binding — DB cross-validation on re-uploadAlways onMachine lock — reject re-upload from different device`SIGNATURE_MACHINE_LOCK=true`CRL certificate revocation check`SIGNATURE_CRL_ENABLED=true`RFC 3161 trusted timestamp via TSA`SIGNATURE_TSA_URL=https://...`For full details see [docs/security.md](docs/security.md). --- Queue ----- [](#queue) Signing runs asynchronously. Start a queue worker: ``` php artisan queue:work ``` To sign synchronously (no queue required): ``` SignDocumentAction::make() // default is now synchronous ``` The action calls `embedAndFinalize()` directly unless you opt in to queued signing: ``` SignDocumentAction::make()->queued() ``` ### Health Score 47 — FairBetter than 93% of packages Maintenance96 Actively maintained with recent releases Popularity12 Limited adoption so far Community8 Small or concentrated contributor base Maturity60 Established project with proven stability Bus Factor1 Top contributor holds 98.5% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
