## Basic usage
|
|
|
|
The example below shows basic usage of xmlseclibs, with a SHA-256 signature.
|
|
|
|
```php
|
|
use RobRichards\XMLSecLibs\XMLSecurityDSig;
|
|
use RobRichards\XMLSecLibs\XMLSecurityKey;
|
|
|
|
// Load the XML to be signed
|
|
$doc = new DOMDocument();
|
|
$doc->load('./path/to/file/tobesigned.xml');
|
|
|
|
// Create a new Security object
|
|
$objDSig = new XMLSecurityDSig();
|
|
// Use the c14n exclusive canonicalization
|
|
$objDSig->setCanonicalMethod(XMLSecurityDSig::EXC_C14N);
|
|
// Sign using SHA-256
|
|
$objDSig->addReference(
|
|
$doc,
|
|
XMLSecurityDSig::SHA256,
|
|
array('http://www.w3.org/2000/09/xmldsig#enveloped-signature')
|
|
);
|
|
|
|
// Create a new (private) Security key
|
|
$objKey = new XMLSecurityKey(XMLSecurityKey::RSA_SHA256, array('type'=>'private'));
|
|
/*
|
|
If key has a passphrase, set it using
|
|
$objKey->passphrase = '<passphrase>';
|
|
*/
|
|
// Load the private key
|
|
$objKey->loadKey('./path/to/privatekey.pem', TRUE);
|
|
|
|
// Sign the XML file
|
|
$objDSig->sign($objKey);
|
|
|
|
// Add the associated public key to the signature
|
|
$objDSig->add509Cert(file_get_contents('./path/to/file/mycert.pem'));
|
|
|
|
// Append the signature to the XML
|
|
$objDSig->appendSignature($doc->documentElement);
|
|
// Save the signed XML
|
|
$doc->save('./path/to/signed.xml');
|
|
```
