[](#version-2)

```
composer require lsnepomuceno/laravel-a1-pdf-sign
```

```
use LSNepomuceno\LaravelA1PdfSign\Facades\A1PdfSign;

$signed = A1PdfSign::newSignature()
    ->certificate($pfxPath, $password)
    ->pdf($pdfPath)
    ->info(name: 'Lucas', reason: 'Contract')
    ->seal()                       // omit for an invisible signature
    ->sign();

$signed->contents();               // string
$signed->save($path);              // path
$signed->download('contract.pdf'); // BinaryFileResponse
```

**Signing appends a revision rather than rebuilding the document.** The original bytes survive, so annotations and form fields are preserved and a document can carry more than one signature — the request in [TCPDF#430](https://github.com/tecnickcom/TCPDF/issues/430), open since 2021.

Signed samples for every profile, including a document carrying six signatures, live in [`samples/`](samples/README.md) — open them in any reader to see what the package produces.

### PAdES profiles

[](#pades-profiles)

ProfileAdds`legacy`ISO 32000-1 detached CMS`pades-b-b`CAdES signed attributes, with ESS `signing-certificate-v2`. **Default**`pades-b-t`plus an RFC 3161 timestamp`pades-b-lt`plus a Document Security Store, so it still verifies after the certificate expires`pades-b-lta`plus an archive timestamp over the whole file```
A1PdfSign::newSignature()
    ->certificate($pfx, $password)
    ->pdf($path)
    ->profile('pades-b-lt')   // needs A1_TSA_URL configured
    ->sign();
```

### Validation

[](#validation)

```
$report = A1PdfSign::validate($pdfPath);

$report->isValid();     // every signature verifies against the bytes it covers
$report->count();       // how many signatures the document carries
$report->signers();     // structured signer identity
```

`isValid()` answers whether each signature matches the document. It does not check the issuer against a trust store — that decision stays with your application.

Configuration is publishable:

```
php artisan vendor:publish --tag=a1-pdf-sign-config
```
