## Firma

Firmado con el certificado de prueba del SDK, el que baja la [guía de inicio](https://fe.kembec.com/empezar/guia-de-inicio/).

Si tu `DigestValue` es este, tu XML es el mismo que el del SDK. Con el certificado de prueba el `SignatureValue` también coincide; con el tuyo cambia, porque depende de tu clave.

## Reproducirlo

Con el SDK instalado como dice la [guía de inicio](https://fe.kembec.com/empezar/guia-de-inicio/#2-instala-el-sdk), baja el caso y el certificado de prueba:

```bash
curl -fsSL --remote-name-all \
  https://fe.kembec.com/sdk/v0.1.0-beta.5/01-invoice-detraction.json \
  https://fe.kembec.com/sdk/v0.1.0-beta.5/test-cert.pem \
  https://fe.kembec.com/sdk/v0.1.0-beta.5/test-key.pem
```

Fírmalo como en la [guía](https://fe.kembec.com/empezar/guia-de-inicio/#2-firma-el-caso-de-prueba): tu `DigestValue` tiene que ser el de arriba.

### PHP

En `firmar.php`, la línea del JSON queda así:

`firmar.php`:

```php
$factura = file_get_contents(__DIR__ . '/01-invoice-detraction.json');
```

```bash
php firmar.php
```

### JavaScript

En `firmar.mjs`, la línea del JSON queda así:

`firmar.mjs`:

```js
const built = JSON.parse(sdk.build(leer('01-invoice-detraction.json')));
```

```bash
node firmar.mjs
```

### Python

En `firmar.py`, la línea del JSON queda así:

`firmar.py`:

```python
built = sunat_sdk.build(leer('01-invoice-detraction.json'))
```

```bash
python firmar.py
```

### CLI

```bash
sunat-sdk build < 01-invoice-detraction.json \
  | sunat-sdk sign --cert test-cert.pem --key test-key.pem > firmada.json
grep -o '"digest_value":"[^"]*"' firmada.json
grep -q '"digest_value":"okrodRhy3nBUgjzTlf4MXzekYDI="' firmada.json && echo "digest ok"
```
