Load and add the private key to the `PrivateKeyStore`:

```
use Selective\XmlDSig\PrivateKeyStore;
// ...

$privateKeyStore = new PrivateKeyStore();

// load a private key from a string
$privateKeyStore->loadFromPem('private key content', 'password');

// or load a private key from a PEM file
$privateKeyStore->loadFromPem(file_get_contents('filename.pem'), 'password');

// load pfx PKCS#12 certificate from a string
$privateKeyStore->loadFromPkcs12('pfx content', 'password');

// or load PKCS#12 certificate from a file
$privateKeyStore->loadFromPkcs12(file_get_contents('filename.p12'), 'password');
```

Define the digest method: sha1, sha224, sha256, sha384, sha512

```
use Selective\XmlDSig\Algorithm;

$algorithm = new Algorithm(Algorithm::METHOD_SHA1);
```

Create a `CryptoSigner` instance:

```
use Selective\XmlDSig\CryptoSigner;

$cryptoSigner = new CryptoSigner($privateKeyStore, $algorithm);
```

Signing:

```
use Selective\XmlDSig\XmlSigner;

// Create a XmlSigner and pass the crypto signer
$xmlSigner = new XmlSigner($cryptoSigner);

// Optional: Set reference URI
$xmlSigner->setReferenceUri('');

// Create a signed XML string
$signedXml = $xmlSigner->signXml('
