SAML Addon
=============
This addon replaces the normal login and registration mechanism with SSO and SLO via a SAML identity provider.
New users are created in the Friendica database when they log in via SAML for the first time. They are given a random password at least 24 characters long.
SAML users with the same usernames/nicknames as existing users will be able to log in as those existing users. Make sure to create SAML accounts for any existing users before activating this addon, or you'll create a situation where a person may claim someone else's account by registering a SAML account with their username.
SSO is triggered when the user visits the Friendica homepage while logged out.
If using KeyCloak as your IdP, make sure the "role_list" scope is either set up to return a single "Role" attribute or to not return one at all. (This addon doesn't need it.) The SAML library used here does not allow multiple attributes with the same name.
To remove the "role_list" from your client in Keycloak, edit the client you created for this addon, click the "Client Scopes" tab, select "role_list" under "Assigned Default Client Scopes," and click "Remove Selected."
For more details on the Keycloak "role_list" issue:

Take care of this folder that could contain private key. Be sure that this folder never is published.
Onelogin PHP Toolkit expects certs for the SP stored at:
* sp.key Private Key
* sp.crt Public cert
* sp_new.crt Future Public cert
Also you can use other cert to sign the metadata of the SP using the:
* metadata.key
* metadata.crt
If you are using composer to install the php-saml toolkit, You should move the certs folder to vendor/onelogin/php-saml/certs

<xs:element name="PreviousSession" type="ExtensionOnlyType">
<xs:annotation>
<xs:documentation>
Indicates that the Principal has been strongly
authenticated in a previous session during which the IdP has set a
cookie in the UA. During the present session the Principal has only
been authenticated by the UA returning the cookie to the IdP.
</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="ResumeSession" type="ExtensionOnlyType">
<xs:annotation>
<xs:documentation>
Rather like PreviousSession but using stronger
security. A secret that was established in a previous session with
the Authentication Authority has been cached by the local system and
is now re-used (e.g. a Master Secret is used to derive new session
keys in TLS, SSL, WTLS).
</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="ZeroKnowledge" type="ExtensionOnlyType">
<xs:annotation>
<xs:documentation>
This element indicates that the Principal has been

</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="AsymmetricDecryption" type="PublicKeyType">
<xs:annotation>
<xs:documentation>
The local system has a private key but it is used
in decryption mode, rather than signature mode. For example, the
Authentication Authority generates a secret and encrypts it using the
local system's public key: the local system then proves it has
decrypted the secret.
</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="AsymmetricKeyAgreement" type="PublicKeyType">
<xs:annotation>
<xs:documentation>
The local system has a private key and uses it for

<h1>About the XML namespace</h1>
<div class="bodytext">
<p>
This schema document describes the XML namespace, in a form
suitable for import by other schema documents.
</p>
<p>
See <a href="http://www.w3.org/XML/1998/namespace.html">
http://www.w3.org/XML/1998/namespace.html</a> and
<a href="http://www.w3.org/TR/REC-xml">
http://www.w3.org/TR/REC-xml</a> for information
about this namespace.
</p>
<p>
Note that local names in this namespace are intended to be
defined only by the World Wide Web Consortium or its subgroups.
The names currently defined in this namespace are listed below.
They should not be used with conflicting semantics by any Working
Group, specification, or document instance.
</p>
<p>
See further below in this document for more information about <a
href="#usage">how to refer to this schema document from your own
XSD schema documents</a> and about <a href="#nsversioning">the

<p>
denotes an attribute whose value
is a language code for the natural language of the content of
any element; its value is inherited. This name is reserved
by virtue of its definition in the XML specification.</p>

<h4>Notes</h4>
<p>
Attempting to install the relevant ISO 2- and 3-letter
codes as the enumerated possible values is probably never
going to be a realistic possibility.

<h2><a name="usage">About this schema document</a></h2>
<div class="bodytext">
<p>
This schema defines attributes and an attribute group suitable
for use by schemas wishing to allow <code>xml:base</code>,
<code>xml:lang</code>, <code>xml:space</code> or
<code>xml:id</code> attributes on elements they define.
</p>
<p>
To enable this, such a schema must import this schema for
the XML namespace, e.g. as follows:
</p>
<pre>
&lt;schema . . .>
. . .
&lt;import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="http://www.w3.org/2001/xml.xsd"/>
</pre>
<p>
or
</p>
<pre>
&lt;import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="http://www.w3.org/2009/01/xml.xsd"/>
</pre>
<p>
Subsequently, qualified reference to any of the attributes or the
group defined below will have the desired effect, e.g.
</p>
<pre>
&lt;type . . .>
. . .
&lt;attributeGroup ref="xml:specialAttrs"/>
</pre>
<p>
will define a type which will schema-validate an instance element
with any of those attributes.

<div class="bodytext">
<p>
In keeping with the XML Schema WG's standard versioning
policy, this schema document will persist at
<a href="http://www.w3.org/2009/01/xml.xsd">
http://www.w3.org/2009/01/xml.xsd</a>.

The schema document at that URI may however change in the future,
in order to remain compatible with the latest version of XML
Schema itself, or with the XML namespace itself. In other words,
if the XML Schema or XML namespaces change, the version of this
document at <a href="http://www.w3.org/2001/xml.xsd">

will change accordingly; the version at

- Add support for RSA-SHA256
Bug Fixes:
- fix bug #5: createDOMDocumentFragment() in decryptNode when data is node
content (patch by Francois Wang)
08 Jul 2008, 1.2.1
Features:
- Attempt to use mhash when hash extension is not present. (Alfredo Cubitos).
- Add fallback to built-in sha1 if both hash and mhash are not available and
throw error for other for other missing hashes. (patch by Olav Morken).
- Add getX509Certificate method to retrieve the x509 cert used for Key.
(patch by Olav Morken).
- Add getValidatedNodes method to retrieve the elements signed by the
signature. (patch by Olav Morken).
- Add insertSignature method for precision signature insertion. Merge
functionality from appendSignature in the process. (Olav Morken, Rob).
- Finally add some tests
Bug Fixes:
- Fix canonicalization for Document node when using PHP < 5.2.
- Add padding for RSA_SHA1. (patch by Olav Morken).
27 Nov 2007, 1.2.0
Features:
- New addReference/List option (overwrite). Boolean flag indicating if URI
value should be overwritten if already existing within document.
Default is TRUE to maintain BC.
18 Nov 2007, 1.1.2
Bug Fixes:
- Remove closing PHP tag to fix extra whitespace characters from being output
11 Nov 2007, 1.1.1
Features:
- Add getRefNodeID() and getRefIDs() methods missed in previous release.
Provide functionality to find URIs of existing reference nodes.
Required by simpleSAMLphp project
Bug Fixes:
- Remove erroneous whitespace causing issues under certain circumastances.
18 Oct 2007, 1.1.0
Features:
- Enable creation of enveloping signature. This allows the creation of
managed information cards.
- Add addObject method for enveloping signatures.
- Add staticGet509XCerts method. Chained certificates within a PEM file can
now be added within the X509Data node.
- Add xpath support within transformations
- Add InclusiveNamespaces prefix list support within exclusive transformations.
Bug Fixes:
- Initialize random number generator for mcrypt_create_iv. (Joan Cornadó).
- Fix an interoperability issue with .NET when encrypting data in CBC mode.
(Joan Cornadó).

#xmlseclibs
xmlseclibs is a library written in PHP for working with XML Encryption and Signatures.
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
xmlseclibs requires PHP version 5.4 or greater. **5.6.24+ recommended for security reasons**
## How to Install
Install with [`composer.phar`](http://getcomposer.org).
```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)
* [OneLogin](https://github.com/onelogin/php-saml)
## 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');
```
