The author of xmlseclibs is Rob Richards.
# Branches
Master is currently the only actively maintained branch.
* master/3.1: Added AES-GCM support requiring 7.1+
* 3.0: Removes mcrypt usage requiring 5.4+ (5.6.24+ recommended for security reasons)
* 2.0: Contains namespace support requiring 5.3+
* 1.4: Contains auto-loader support while also maintaining backwards compatiblity with the older 1.3 version using the xmlseclibs.php file. Supports PHP 5.2+
# Requirements

```sh
php composer.phar require "robrichards/xmlseclibs"
```
## Use cases
xmlseclibs is being used in many different software.
* [SimpleSAMLPHP](https://github.com/simplesamlphp/simplesamlphp)
* [LightSAML](https://github.com/lightsaml/lightsaml)

## 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');
```
