The only part of the library which has to be used and - * isn't documented in full here is the store required to create an - * Auth_OpenID_Consumer instance. More on the abstract store type and - * concrete implementations of it that are provided in the - * documentation for the Auth_OpenID_Consumer constructor. - * - * OVERVIEW - * - * The OpenID identity verification process most commonly uses the - * following steps, as visible to the user of this library: - * - * 1. The user enters their OpenID into a field on the consumer's - * site, and hits a login button. - * 2. The consumer site discovers the user's OpenID server using the - * YADIS protocol. - * 3. The consumer site sends the browser a redirect to the identity - * server. This is the authentication request as described in - * the OpenID specification. - * 4. The identity server's site sends the browser a redirect back - * to the consumer site. This redirect contains the server's - * response to the authentication request. - * - * The most important part of the flow to note is the consumer's site - * must handle two separate HTTP requests in order to perform the full - * identity check. - * - * LIBRARY DESIGN - * - * This consumer library is designed with that flow in mind. The goal - * is to make it as easy as possible to perform the above steps - * securely. - * - * At a high level, there are two important parts in the consumer - * library. The first important part is this module, which contains - * the interface to actually use this library. The second is the - * Auth_OpenID_Interface class, which describes the interface to use - * if you need to create a custom method for storing the state this - * library needs to maintain between requests. - * - * In general, the second part is less important for users of the - * library to know about, as several implementations are provided - * which cover a wide variety of situations in which consumers may use - * the library. - * - * This module contains a class, Auth_OpenID_Consumer, with methods - * corresponding to the actions necessary in each of steps 2, 3, and 4 - * described in the overview. Use of this library should be as easy - * as creating an Auth_OpenID_Consumer instance and calling the - * methods appropriate for the action the site wants to take. - * - * STORES AND DUMB MODE - * - * OpenID is a protocol that works best when the consumer site is able - * to store some state. This is the normal mode of operation for the - * protocol, and is sometimes referred to as smart mode. There is - * also a fallback mode, known as dumb mode, which is available when - * the consumer site is not able to store state. This mode should be - * avoided when possible, as it leaves the implementation more - * vulnerable to replay attacks. - * - * The mode the library works in for normal operation is determined by - * the store that it is given. The store is an abstraction that - * handles the data that the consumer needs to manage between http - * requests in order to operate efficiently and securely. - * - * Several store implementation are provided, and the interface is - * fully documented so that custom stores can be used as well. See - * the documentation for the Auth_OpenID_Consumer class for more - * information on the interface for stores. The implementations that - * are provided allow the consumer site to store the necessary data in - * several different ways, including several SQL databases and normal - * files on disk. - * - * There is an additional concrete store provided that puts the system - * in dumb mode. This is not recommended, as it removes the library's - * ability to stop replay attacks reliably. It still uses time-based - * checking to make replay attacks only possible within a small - * window, but they remain possible within that window. This store - * should only be used if the consumer site has no way to retain data - * between requests at all. - * - * IMMEDIATE MODE - * - * In the flow described above, the user may need to confirm to the - * lidentity server that it's ok to authorize his or her identity. - * The server may draw pages asking for information from the user - * before it redirects the browser back to the consumer's site. This - * is generally transparent to the consumer site, so it is typically - * ignored as an implementation detail. - * - * There can be times, however, where the consumer site wants to get a - * response immediately. When this is the case, the consumer can put - * the library in immediate mode. In immediate mode, there is an - * extra response possible from the server, which is essentially the - * server reporting that it doesn't have enough information to answer - * the question yet. - * - * USING THIS LIBRARY - * - * Integrating this library into an application is usually a - * relatively straightforward process. The process should basically - * follow this plan: - * - * Add an OpenID login field somewhere on your site. When an OpenID - * is entered in that field and the form is submitted, it should make - * a request to the your site which includes that OpenID URL. - * - * First, the application should instantiate the Auth_OpenID_Consumer - * class using the store of choice (Auth_OpenID_FileStore or one of - * the SQL-based stores). If the application has a custom - * session-management implementation, an object implementing the - * {@link Auth_Yadis_PHPSession} interface should be passed as the - * second parameter. Otherwise, the default uses $_SESSION. - * - * Next, the application should call the Auth_OpenID_Consumer object's - * 'begin' method. This method takes the OpenID URL. The 'begin' - * method returns an Auth_OpenID_AuthRequest object. - * - * Next, the application should call the 'redirectURL' method of the - * Auth_OpenID_AuthRequest object. The 'return_to' URL parameter is - * the URL that the OpenID server will send the user back to after - * attempting to verify his or her identity. The 'trust_root' is the - * URL (or URL pattern) that identifies your web site to the user when - * he or she is authorizing it. Send a redirect to the resulting URL - * to the user's browser. - * - * That's the first half of the authentication process. The second - * half of the process is done after the user's ID server sends the - * user's browser a redirect back to your site to complete their - * login. - * - * When that happens, the user will contact your site at the URL given - * as the 'return_to' URL to the Auth_OpenID_AuthRequest::redirectURL - * call made above. The request will have several query parameters - * added to the URL by the identity server as the information - * necessary to finish the request. - * - * Lastly, instantiate an Auth_OpenID_Consumer instance as above and - * call its 'complete' method, passing in all the received query - * arguments. - * - * There are multiple possible return types possible from that - * method. These indicate the whether or not the login was successful, - * and include any additional information appropriate for their type. - * - * PHP versions 4 and 5 - * - * LICENSE: See the COPYING file included in this distribution. - * - * @package OpenID - * @author JanRain, Inc. <openid@janrain.com> - * @copyright 2005-2008 Janrain, Inc. - * @license http://www.apache.org/licenses/LICENSE-2.0 Apache - */ - -/** - * Require utility classes and functions for the consumer. - */ -require_once "Auth/OpenID.php"; -require_once "Auth/OpenID/Message.php"; -require_once "Auth/OpenID/HMAC.php"; -require_once "Auth/OpenID/Association.php"; -require_once "Auth/OpenID/CryptUtil.php"; -require_once "Auth/OpenID/DiffieHellman.php"; -require_once "Auth/OpenID/KVForm.php"; -require_once "Auth/OpenID/Nonce.php"; -require_once "Auth/OpenID/Discover.php"; -require_once "Auth/OpenID/URINorm.php"; -require_once "Auth/Yadis/Manager.php"; -require_once "Auth/Yadis/XRI.php"; - -/** - * This is the status code returned when the complete method returns - * successfully. - */ -define('Auth_OpenID_SUCCESS', 'success'); - -/** - * Status to indicate cancellation of OpenID authentication. - */ -define('Auth_OpenID_CANCEL', 'cancel'); - -/** - * This is the status code completeAuth returns when the value it - * received indicated an invalid login. - */ -define('Auth_OpenID_FAILURE', 'failure'); - -/** - * This is the status code completeAuth returns when the - * {@link Auth_OpenID_Consumer} instance is in immediate mode, and the - * identity server sends back a URL to send the user to to complete his - * or her login. - */ -define('Auth_OpenID_SETUP_NEEDED', 'setup needed'); - -/** - * This is the status code beginAuth returns when the page fetched - * from the entered OpenID URL doesn't contain the necessary link tags - * to function as an identity page. - */ -define('Auth_OpenID_PARSE_ERROR', 'parse error'); - -/** - * An OpenID consumer implementation that performs discovery and does - * session management.

Examine the incoming request to determine its nature and validity. - * 2. Make a decision about how to respond to this request. - * 3. Format the response according to the protocol. - * - * The first and last of these tasks may performed by the {@link - * Auth_OpenID_Server::decodeRequest()} and {@link - * Auth_OpenID_Server::encodeResponse} methods. Who gets to do the - * intermediate task -- deciding how to respond to the request -- will - * depend on what type of request it is. - * - * If it's a request to authenticate a user (a 'checkid_setup' or - * 'checkid_immediate' request), you need to decide if you will assert - * that this user may claim the identity in question. Exactly how you - * do that is a matter of application policy, but it generally - * involves making sure the user has an account with your system and - * is logged in, checking to see if that identity is hers to claim, - * and verifying with the user that she does consent to releasing that - * information to the party making the request. - * - * Examine the properties of the {@link Auth_OpenID_CheckIDRequest} - * object, and if and when you've come to a decision, form a response - * by calling {@link Auth_OpenID_CheckIDRequest::answer()}. - * - * Other types of requests relate to establishing associations between - * client and server and verifing the authenticity of previous - * communications. {@link Auth_OpenID_Server} contains all the logic - * and data necessary to respond to such requests; just pass it to - * {@link Auth_OpenID_Server::handleRequest()}. - * - * OpenID Extensions - * - * Do you want to provide other information for your users in addition - * to authentication? Version 1.2 of the OpenID protocol allows - * consumers to add extensions to their requests. For example, with - * sites using the Simple Registration - * Extension - * (http://www.openidenabled.com/openid/simple-registration-extension/), - * a user can agree to have their nickname and e-mail address sent to - * a site when they sign up. - * - * Since extensions do not change the way OpenID authentication works, - * code to handle extension requests may be completely separate from - * the {@link Auth_OpenID_Request} class here. But you'll likely want - * data sent back by your extension to be signed. {@link - * Auth_OpenID_ServerResponse} provides methods with which you can add - * data to it which can be signed with the other data in the OpenID - * signature. - * - * For example: - * - * <pre> // when request is a checkid_* request - * $response = $request->answer(true); - * // this will a signed 'openid.sreg.timezone' parameter to the response - * response.addField('sreg', 'timezone', 'America/Los_Angeles')</pre> - * - * Stores - * - * The OpenID server needs to maintain state between requests in order - * to function. Its mechanism for doing this is called a store. The - * store interface is defined in Interface.php. Additionally, several - * concrete store implementations are provided, so that most sites - * won't need to implement a custom store. For a store backed by flat - * files on disk, see {@link Auth_OpenID_FileStore}. For stores based - * on MySQL, SQLite, or PostgreSQL, see the {@link - * Auth_OpenID_SQLStore} subclasses. - * - * Upgrading - * - * The keys by which a server looks up associations in its store have - * changed in version 1.2 of this library. If your store has entries - * created from version 1.0 code, you should empty it. - * - * PHP versions 4 and 5 - * - * LICENSE: See the COPYING file included in this distribution. - * - * @package OpenID - * @author JanRain, Inc. <openid@janrain.com> - * @copyright 2005-2008 Janrain, Inc. - * @license http://www.apache.org/licenses/LICENSE-2.0 Apache - */ - -/** - * Required imports - */ -require_once "Auth/OpenID.php"; -require_once "Auth/OpenID/Association.php"; -require_once "Auth/OpenID/CryptUtil.php"; -require_once "Auth/OpenID/BigMath.php"; -require_once "Auth/OpenID/DiffieHellman.php"; -require_once "Auth/OpenID/KVForm.php"; -require_once "Auth/OpenID/TrustRoot.php"; -require_once "Auth/OpenID/ServerRequest.php"; -require_once "Auth/OpenID/Message.php"; -require_once "Auth/OpenID/Nonce.php"; - -define('AUTH_OPENID_HTTP_OK', 200); -define('AUTH_OPENID_HTTP_REDIRECT', 302); -define('AUTH_OPENID_HTTP_ERROR', 400); - -/** - * @access private - */ -global $_Auth_OpenID_Request_Modes; -$_Auth_OpenID_Request_Modes = array('checkid_setup', - 'checkid_immediate'); - -/** - * @access private - */ -define('Auth_OpenID_ENCODE_KVFORM', 'kfvorm'); - -/** - * @access private - */ -define('Auth_OpenID_ENCODE_URL', 'URL/redirect'); - -/** - * @access private - */ -define('Auth_OpenID_ENCODE_HTML_FORM', 'HTML form'); - -/** - * @access private - */ -function Auth_OpenID_isError($obj, $cls = 'Auth_OpenID_ServerError') -{ - return is_a($obj, $cls); -} - -/** - * An error class which gets instantiated and returned whenever an - * OpenID protocol error occurs.

The XRDS - * document found during discovery should have service descriptions, - * which can be accessed by calling - * - * <pre> $service_list = $yadis_object->services();</pre> - * - * which returns an array of objects which describe each service. - * These objects are instances of Auth_Yadis_Service. Each object - * describes exactly one whole Service element, complete with all of - * its Types and URIs (no expansion is performed). The common use - * case for using the service objects returned by services() is to - * write one or more filter functions and pass those to services(): - * - * <pre> $service_list = $yadis_object->services( - * array("filterByURI", - * "filterByExtension"));</pre> - * - * The filter functions (whose names appear in the array passed to - * services()) take the following form: - * - * <pre> function myFilter(&$service) { - * // Query $service object here.

You can specify that a given service object will - * be returned ONLY if it matches ALL specified filters by changing - * the match mode of services(): - * - * <pre> $yadis_object->services(array("filter1", "filter2"), - * SERVICES_YADIS_MATCH_ALL);</pre> - * - * See {@link SERVICES_YADIS_MATCH_ALL} and {@link - * SERVICES_YADIS_MATCH_ANY}. - * - * Services described in an XRDS should have a library which you'll - * probably be using.

JSON is a text format that is - * completely language independent but uses conventions that are familiar - * to programmers of the C-family of languages, including C, C++, C#, Java, - * JavaScript, Perl, TCL, and many others. These properties make JSON an - * ideal data-interchange language. - * - * This package provides a simple encoder and decoder for JSON notation. It - * is intended for use with client-side Javascript applications that make - * use of HTTPRequest to perform server communication functions - data can - * be encoded into JSON notation for use in a client-side javascript, or - * decoded from incoming Javascript requests. JSON format is native to - * Javascript, and can be directly eval()'ed with no further parsing - * overhead - * - * All strings should be in ASCII or UTF-8 format! - * - * LICENSE: Redistribution and use in source and binary forms, with or - * without modification, are permitted provided that the following - * conditions are met: Redistributions of source code must retain the - * above copyright notice, this list of conditions and the following - * disclaimer.

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this.

You can use span-level -HTML tags anywhere in a Markdown document, and you can use block level -HTML tags (like <div> and <table> as well). - -For more information about Markdown's syntax, see: - -<http://daringfireball.net/projects/markdown/> - - -Bugs ----- - -To file bug reports please send email to: - -<michel.fortin@michelf.com> - -Please include with your report: (1) the example input; (2) the output you -expected; (3) the output Markdown actually produced. - - -Version History ---------------- - -See the readme file for detailed release notes for this version. - - -Copyright and License ---------------------- - -PHP Markdown -Copyright (c) 2004-2008 Michel Fortin -<http://www.michelf.com/> -All rights reserved. - -Based on Markdown -Copyright (c) 2003-2006 John Gruber -<http://daringfireball.net/> -All rights reserved. - -Redistribution and use in source and binary forms, with or without -modification, are permitted provided that the following conditions are -met: - -* Redistributions of source code must retain the above copyright notice, - this list of conditions and the following disclaimer. - -* Redistributions in binary form must reproduce the above copyright - notice, this list of conditions and the following disclaimer in the - documentation and/or other materials provided with the distribution. - -* Neither the name "Markdown" nor the names of its contributors may - be used to endorse or promote products derived from this software - without specific prior written permission. - -This software is provided by the copyright holders and contributors "as -is" and any express or implied warranties, including, but not limited -to, the implied warranties of merchantability and fitness for a -particular purpose are disclaimed.
