-# ZeroBin version history #
+# PrivateBin version history
 
-  * **Alpha 0.8 (2012-04-11):**
-    * Source code not published yet.
-    * Interface completely redesigned. Icons added.
-    * Now properly supports IE6/7 (ugly display, but it works. "Clone" button is disabled though.)
-    * Added one level of depth for storage directories (This is better for higher load servers).
-    * php version is now checked (min: 5.2.6)
-    * Better checks on posted json data on server.
-    * Added "1 year" expiration.
-    * URLs are now converted to clickable links. This include http, https, ftp and magnet links.
-    * Clickable links include ''rel="nofollow"'' to discourage SEO.
-    * On my public service (http://sebsauvage.net/paste/)
-      * All data will be deleted (you were warned - this is a test service)
-      * Default paste expiration is now 1 month to prevent clogging-up my host.
-  * **Alpha 0.9 (2012-04-11):**
-    * Oh bummer... IE 8 is as shitty as IE6/7: Its does not seem to support ''white-space:pre-wrap'' correctly. I had to activate the special handling mode. I still have to test IE 9.
-  * **Alpha 0.10 (2012-04-12):**
-    * IE9 does not seem to correctly support ''pre-wrap'' either. Special handling mode activated for all version of IE<10. (Note: **ALL other browsers** correctly support this feature.) 
-  * **Alpha 0.11 (2012-04-12):**
-    * Automatically ignore parameters (such as &utm_source=...) added //after// the anchor by some stupid Web 2.0 services.
-    * First public release.
-  * **Alpha 0.12 (2012-04-18):**
-    * **DISCUSSIONS !** Now you can enable discussions on your pastes. Of course, posted comments and nickname are also encrypted and the server cannot see them.
-    * This feature implies a change in storage format. You will have to delete all previous pastes in your ZeroBin. 
-    * Added [[php:vizhash_gd|Vizhash]] as avatars, so you can match posters IP addresses without revealing them. (Same image = same IP). Of course the IP address cannot be deduced from the Vizhash.
-    * Remaining time before expiration is now displayed.
-    * Explicit tags were added to CSS and jQuery selectors (eg. div#aaa instead of #aaa) to speed up browser. 
-    * Better cleaning of the URL (to make sure the key is not broken by some stupid redirection service)
-  * **Alpha 0.13 (2012-04-18):**
-    * FIXED: ''imageantialias()'' call removed because it's not really usefull and can be a problem on most hosts (if GD is not compiled in php).
-    * FIXED: $error not properly initialized in index.php
-  * **Alpha 0.14 (2012-04-20):**
-    * ADDED: GD presence is checked. 
-    * CHANGED: Traffic limiter data files moved to data/ (→easier rights management)
-    * ADDED: "Burn after reading" implemented. Opening the URL will display the paste and immediately destroy it on server.
-  * **Alpha 0.15 (2012-04-20):**
-    * FIXED: 2 minor corrections to avoid notices in php log.
-    * FIXED: Sources converted to UTF-8.
-  * **Alpha 0.15 (2012-04-20):**
-    * FIXED: 2 minor corrections to avoid notices in php log.

-    * FIXED minor php warnings.
-    * FIXED: zerobin.js reformated and properly commented.
-    * FIXED: Directory structure re-organized.
-    * CHANGED: URL shortening button was removed. (It was bad for privacy.)
-  * **Alpha 0.17 (2013-02-23)**:
-    * ADDED: Deletion URL.

-    * improved regex checks.
-    * larger server alt on installation.
+  * **1.1.1 (2017-10-06)**

+    * FIXED: Automatic purging deleting non-expiring pastes, when using database store (#149)
+  * **1.0 (2016-08-25)**
+    * ADDED: Translations for Slowene and Chinese
+    * ADDED: re-introduced (optional) URL shortener support, which was removed back in version 0.16 for privacy concerns
+    * ADDED: Preview tab, helpful for writing markdown code or check the source code rendering
+    * ADDED: Automatic purging of expired pastes, done on paste creation
+    * ADDED: Option to disable icons in discussions (will only affect newly created pastes)

+    * CHANGED: Introduced content security policy header to reduce cross site scripting (XSS) risks
+    * CHANGED: Added SHA512 subresource integrity hashes for all javascript includes to reduce the risk of manipulated scripts and easier detection of such
+    * CHANGED: Refactored PHP code to conform to PSR-4 and PSR-2 standards
+    * CHANGED: Switched to Identicons as the default for comments with nicknames
+    * CHANGED: Vizhash is now optional and based on (128 byte) SHA512 HMAC instead of (144 byte) combination of MD5, SHA1 and a reversal of that string
+    * FIXED: Content-type negociation for HTML in certain uncommon browser configurations
+    * FIXED: JavaScript error displayed before page is loaded or during attachment load
+    * FIXED: Don't strip space characters at beginning or end of optional password
+    * FIXED: Various UI glitches in mobile version or on smaller desktops with language menu, button spacing and long URLs
+    * FIXED: Back button now works as expected after switching to raw text view of a paste
+    * FIXED: Reactivated second error message above send comment button to ensure its visibility when the main error message is outside the viewport
+    * FIXED: Raw text now displays original markdown instead of rendered HTML
+    * FIXED: Removed unused code detected with the help of various code review tools
+    * FIXED: Table format for PostgreSQL, making it possible to use PostgreSQL as backend in addition to MySQL, SQLite and flat files

+    * CHANGED: Database structure to store attachments, allowing larger attachments to be stored (depending on maximum BLOB size of database backend)
+    * CHANGED: Refactored data model, traffic limiting & request handling
+  * **0.21.1 (2015-09-21)**:
+    * FIXING: lost meta data when using DB model instead of flat files
+    * FIXING: mobile navbar getting triggered on load
+    * CHANGED: database table "paste" gets automatically extended with a "meta" column
+    * CHANGED: navbar of "bootstrap" template now spans full width of view port on large screens
+  * **0.21 (2015-09-19)**:
+    * ADDED: Translations for German, French and Polish, language selection menu (optional)
+    * ADDED: File upload and image display support (optional)
+    * ADDED: Markdown format support
+    * ADDED: "bootstrap-compact" template that hides some of the options in a drop down menu to ensure the nav bar fitting on one line on smaller screen sizes
+    * FIXING: Various usability issues with different screen sizes / device types in the "bootstrap" template
+    * CHANGED: Instead of having different options to enable and preselect certain formats there is now a generic `[formatter_options]` section where formats can be added to the displayed format drop down menu. A `defaultformatter` can be set, it defaults to "plaintext". The `syntaxhighlighting` configuration got deprecated.
+    * `zerobin.js` got a major refactoring:
+      * moved from global namespace into anonymous function
+      * events are no longer set via "onclick" attributes in the templates, but bound by from JS side
+      * for simpler maintenance the functions were grouped into objects: zerobin (display logic, event handling), filter (compression,
+encryption), i18n (translation, counterpart of i18n.php) and helper (stateless utilities)
+    * Wiki pages were added to address common topics:
+      * [Upgrading from ZeroBin 0.19 Alpha](https://github.com/PrivateBin/PrivateBin/wiki/Upgrading-from-ZeroBin-0.19-Alpha)
+      * [Directory of public PrivateBin servers](https://github.com/PrivateBin/PrivateBin/wiki/PrivateBin-Directory)
+      * [Translation](https://github.com/PrivateBin/PrivateBin/wiki/Translation)
+      * [Templates](https://github.com/PrivateBin/PrivateBin/wiki/Templates)
+  * **0.20 (2015-09-03)**:
+    * ADDED: Password protected pastes (optional)
+    * ADDED: configuration options for highlighting, password, discussions, expiration times, rate limiting
+    * ADDED: JSON-only retrieval of paste incl. discussion, used to be able to refresh paste when posting a comment
+    * ADDED: bootstrap CSS based template
+    * CHANGED: "Burn after reading" pastes are now deleted only after the paste was successfully decrypted via callback. This prevents accidental deletion by chatbots following URLs and the like. Usage of a password is suggested to ensure only the desired recipient is able to encrypt it.
+    * CHANGED: the "opendiscussion" option now only controls if the discussion checkbox is preselected. Use "discussion = false" to disable the discussion feature completely (which also removes the checkbox from the template).
+    * FIXING: Behaviour of several conflicting configuration options. As a general measure unit tests for 9 of the options and all their possible configurations were added via a unit test generator.
+    * updated JS libraries: jquery to 1.11.3, sjcl to 1.0.2, base64.js to 2.1.9, deflate to 0.5, inflate to 0.3 and prettify to latest
+    * generally improved documentation, both inline phpdoc / JSdoc source code documentation, as well as Wiki pages on installation, configuration, development and JSON-API
+  * **Alpha 0.19 (2013-07-05)**:
+    * Corrected XSS security flaw which affected IE<10. Other browsers were not affected.
+    * Corrected spacing display in IE<10.
   * **Alpha 0.18 (2013-02-24)**:
     * ADDED: The resulting URL is automatically selected after pressing "Send". You just have to press CTRL+C.
     * ADDED: Automatic syntax highlighting for 53 languages using highlight.js

     * ADDED: Better json checking (including entropy).
     * ADDED: Added version to js/css assets URLs in order to prevent some abusive caches to serve an obsolete version of these files when ZeroBin is upgraded.
     * "Burn after reading" option has been moved out of Expiration combo to a separate checkbox. Reason is: You can prevent a read-once paste to be available ad vitam eternam on the net.

+  * **Alpha 0.12 (2012-04-18):**
+    * **DISCUSSIONS !** Now you can enable discussions on your pastes. Of course, posted comments and nickname are also encrypted and the server cannot see them.
+    * This feature implies a change in storage format. You will have to delete all previous pastes in your ZeroBin. 
+    * Added [[php:vizhash_gd|Vizhash]] as avatars, so you can match posters IP addresses without revealing them. (Same image = same IP). Of course the IP address cannot be deduced from the Vizhash.
+    * Remaining time before expiration is now displayed.
+    * Explicit tags were added to CSS and jQuery selectors (eg. div#aaa instead of #aaa) to speed up browser. 
+    * Better cleaning of the URL (to make sure the key is not broken by some stupid redirection service)

+    * Oh bummer... IE 8 is as shitty as IE6/7: Its does not seem to support ''white-space:pre-wrap'' correctly. I had to activate the special handling mode. I still have to test IE 9.
+  * **Alpha 0.8 (2012-04-11):**
+    * Source code not published yet.
+    * Interface completely redesigned. Icons added.
+    * Now properly supports IE6/7 (ugly display, but it works. "Clone" button is disabled though.)
+    * Added one level of depth for storage directories (This is better for higher load servers).
+    * php version is now checked (min: 5.2.6)
+    * Better checks on posted json data on server.
+    * Added "1 year" expiration.
+    * URLs are now converted to clickable links. This include http, https, ftp and magnet links.
+    * Clickable links include ''rel="nofollow"'' to discourage SEO.
+    * On my public service (http://sebsauvage.net/paste/)
+      * All data will be deleted (you were warned - this is a test service)
+      * Default paste expiration is now 1 month to prevent clogging-up my host.

-Installation
-============
+# Installation
 
-For Administrators
-------------------
+**TL;DR:** Download the
+[latest release archive](https://github.com/PrivateBin/PrivateBin/releases/latest)
+and extract it in your web hosts folder where you want to install your PrivateBin
+instance. We try to provide a mostly safe default configuration, but we urge you to
+check the [security section](#hardening-and-security) below and the [configuration
+options](#configuration) to adjust as you see fit.
 
-In the index.php in the main folder you can define a different PATH. This is 
-useful if you want to secure your installation and want to move the 
-configuration, data files, templates and PHP libraries (directories cfg, data, 
-lib, tpl and tst) outside of your document root. This new location must still 
-be accessible to your webserver / PHP process.
+**NOTE:** See [our FAQ](https://github.com/PrivateBin/PrivateBin/wiki/FAQ#how-can-i-securely-clonedownload-your-project) for information how to securely download the PrivateBin release files.
 
-> ### PATH Example ###
-> Your zerobin installation lives in a subfolder called "paste" inside of your 
-> document root. The URL looks like this:
+### Minimal requirements
+
+- PHP version 5.4 or above
+- _one_ of the following sources of cryptographically safe randomness is required:
+  - PHP 7 or higher
+  - [Libsodium](https://download.libsodium.org/libsodium/content/installation/) and it's [PHP extension](https://paragonie.com/book/pecl-libsodium/read/00-intro.md#installing-libsodium)
+  - open_basedir access to `/dev/urandom`
+  - mcrypt extension
+  - com_dotnet extension
+  
+  Mcrypt needs to be able to access `/dev/urandom`. This means if `open_basedir` is set, it must include this file.
+- GD extension
+- some disk space or (optionally) a database supported by [PDO](https://secure.php.net/manual/book.pdo.php)
+- ability to create files and folders in the installation directory and the PATH defined in index.php
+- A web browser with javascript support
+
+## Hardening and security
+
+### Changing the path
+
+In the index.php you can define a different `PATH`. This is useful to secure your
+installation. You can move the configuration, data files, templates and PHP
+libraries (directories cfg, doc, data, lib, tpl, tst and vendor) outside of your
+document root. This new location must still be accessible to your webserver / PHP
+process (see also
+[open_basedir setting](https://secure.php.net/manual/en/ini.core.php#ini.open-basedir)).
+
+> #### PATH Example
+> Your PrivateBin installation lives in a subfolder called "paste" inside of
+> your document root. The URL looks like this:
 > http://example.com/paste/
-> The ZeroBin folder on your webserver is really:
+>
+> The full path of PrivateBin on your webserver is:
 > /home/example.com/htdocs/paste
 > 
 > When setting the path like this:
-> define('PATH', '../../secret/zerobin/');
-> ZeroBin will look for your includes here:
-> /home/example.com/secret/zerobin
+> define('PATH', '../../secret/privatebin/');
+>
+> PrivateBin will look for your includes / data here:
+> /home/example.com/secret/privatebin
 
-In the file "cfg/conf.ini" you can configure ZeroBin. The config file is 
-divided into multiple sections, which are enclosed in square brackets. In the 
-"[main]" section you can enable or disable the discussion feature, set the 
-limit of stored pastes and comments in bytes. The "[traffic]" section lets you 
-set a time limit in seconds. Users may not post more often then this limit to 
-your ZeroBin.
+### Transport security
 
-Finally the "[model]" and "[model_options]" sections let you configure your 
-favourite way of storing the pastes and discussions on your server. 
-"zerobin_data" is the default model, which stores everything in files in the 
-data folder. This is the recommended setup for low traffic sites. Under high 
-load, in distributed setups or if you are not allowed to store files locally, 
-you might want to switch to the "zerobin_db" model. This lets you store your 
-data in a database. Basically all databases that are supported by PDO (PHP 
-data objects) may be used. Automatic table creation is provided for pdo_ibm, 
-pdo_informix, pdo_mssql, pdo_mysql, pdo_oci, pdo_pgsql and pdo_sqlite. You may 
-want to provide a table prefix, if you have to share the zerobin database with 
-another application. The table prefix option is called "tbl".
+When setting up PrivateBin, also set up HTTPS, if you haven't already. Without HTTPS
+PrivateBin is not secure, as the javascript files could be manipulated during transmission.
+For more information on this, see our [FAQ entry on HTTPS setup](https://github.com/PrivateBin/PrivateBin/wiki/FAQ#how-should-i-setup-https).
 
-> ### Note ###
-> The "zerobin_db" model has only been tested with SQLite and MySQL, although
-> it would not be recommended to use SQLite in a production environment. If you
-> gain any experience running ZeroBin on other RDBMS, please let us know.
+## Configuration
 
-For reference or if you want to create the table schema for yourself:
+In the file `cfg/conf.php` you can configure PrivateBin. A `cfg/conf.sample.php`
+is provided containing all options and default values. You can copy it to
+`cfg/conf.php` and adapt it as needed. The config file is divided into multiple
+sections, which are enclosed in square brackets.
 
-    CREATE TABLE prefix_paste (
-        dataid CHAR(16),
-        data TEXT,
-        postdate INT,
-        expiredate INT,
-        opendiscussion INT,
-        burnafterreading INT
-    );
-    
-    CREATE TABLE prefix_comment (
-        dataid CHAR(16),
-        pasteid CHAR(16),
-        parentid CHAR(16),
-        data TEXT,
-        nickname VARCHAR(255),
-        vizhash TEXT,
-        postdate INT
-    );
+In the `[main]` section you can enable or disable the discussion feature, set
+the limit of stored pastes and comments in bytes. The `[traffic]` section lets
+you set a time limit in seconds. Users may not post more often then this limit
+to your PrivateBin installation.
 
-For Developers 
---------------
-If you want to create your own data models, you might want to know how the 
-arrays, that you have to store, look like:
+More details can be found in the
+[configuration documentation](https://github.com/PrivateBin/PrivateBin/wiki/Configuration).
 
-    public function create($pasteid, $paste)
-    {
-        $pasteid = substr(hash('md5', $paste['data']), 0, 16);
-        
-        $paste['data']                      // text
-        $paste['meta']['postdate']          // int UNIX timestamp
-        $paste['meta']['expire_date']       // int UNIX timestamp
-        $paste['meta']['opendiscussion']    // true (if false it is unset)
-        $paste['meta']['burnafterreading']  // true (if false it is unset; if true, then opendiscussion is unset)
-    }
-    
-    public function createComment($pasteid, $parentid, $commentid, $comment)
-    {
-        $pasteid  // the id of the paste this comment belongs to
-        $parentid // the id of the parent of this comment, may be the paste id itself
-        $commentid = substr(hash('md5', $paste['data']), 0, 16);
-        
-        $comment['data']                    // text
-        $comment['meta']['nickname']        // text or null (if anonymous)
-        $comment['meta']['vizhash']         // text or null (if anonymous)
-        $comment['meta']['postdate']        // int UNIX timestamp
-    }
+## Advanced installation
 
+### Web server configuration
+
+A `robots.txt` file is provided in the root dir of PrivateBin. It disallows all
+robots from accessing your pastes. It is recommend to place it into the root of
+your web directory if you have installed PrivateBin in a subdirectory. Make sure
+to adjust it, so that the file paths match your installation. Of course also
+adjust the file if you already use a `robots.txt`.
+
+A `.htaccess.disabled` file is provided in the root dir of PrivateBin. It blocks
+some known robots and link-scanning bots. If you use Apache, you can rename the
+file to `.htaccess` to enable this feature. If you use another webserver, you
+have to configure it manually to do the same.
+
+### On using Cloudflare
+
+If you want to use PrivateBin behind Cloudflare, make sure you have disabled the Rocket
+loader and unchecked "Javascript" for Auto Minify, found in your domain settings,
+under "Speed". (More information
+[in this FAQ entry](https://github.com/PrivateBin/PrivateBin/wiki/FAQ#user-content-how-to-make-privatebin-work-when-using-cloudflare-for-ddos-protection))
+
+### Using a database instead of flat files
+
+In the configuration file the `[model]` and `[model_options]` sections let you
+configure your favourite way of storing the pastes and discussions on your
+server.
+
+`Filesystem` is the default model, which stores everything in files in the
+data folder. This is the recommended setup for most sites.
+
+Under high load, in distributed setups or if you are not allowed to store files
+locally, you might want to switch to the `Database` model. This lets you
+store your data in a database. Basically all databases that are supported by
+[PDO](https://secure.php.net/manual/en/book.pdo.php) may be used. Automatic table
+creation is provided for `pdo_ibm`, `pdo_informix`, `pdo_mssql`, `pdo_mysql`,
+`pdo_oci`, `pdo_pgsql` and `pdo_sqlite`. You may want to provide a table prefix,
+if you have to share the PrivateBin database with another application or you want
+to use a prefix for
+[security reasons](https://security.stackexchange.com/questions/119510/is-using-a-db-prefix-for-tables-more-secure).
+The table prefix option is called `tbl`.
+
+> #### Note
+> The `Database` model has only been tested with SQLite, MySQL and PostgreSQL,
+> although it would not be recommended to use SQLite in a production environment.
+> If you gain any experience running PrivateBin on other RDBMS, please let us
+> know.
+
+For reference or if you want to create the table schema for yourself (replace
+`prefix_` with your own table prefix and create the table schema with phpMyAdmin
+or the MYSQL console):
+
+```sql
+CREATE TABLE prefix_paste (
+    dataid CHAR(16) NOT NULL,
+    data BLOB,
+    postdate INT,
+    expiredate INT,
+    opendiscussion INT,
+    burnafterreading INT,
+    meta TEXT,
+    attachment MEDIUMBLOB,
+    attachmentname BLOB,
+    PRIMARY KEY (dataid)
+);
+
+CREATE TABLE prefix_comment (
+    dataid CHAR(16),
+    pasteid CHAR(16),
+    parentid CHAR(16),
+    data BLOB,
+    nickname BLOB,
+    vizhash BLOB,
+    postdate INT,
+    PRIMARY KEY (dataid)
+);
+CREATE INDEX parent ON prefix_comment(pasteid);
+
+CREATE TABLE prefix_config (
+    id CHAR(16) NOT NULL, value TEXT, PRIMARY KEY (id)
+);
+INSERT INTO prefix_config VALUES('VERSION', '1.1');
+```
+
+In PostgreSQL, the attachment column needs to be TEXT and not BLOB or MEDIUMBLOB.

+
+_Version 2, June 1991_
+_Copyright © 1989, 1991 Free Software Foundation, Inc.,_
+_51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA_
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+### Preamble
+
+The licenses for most software are designed to take away your
+freedom to share and change it.  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.
+
+### 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.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+### NO WARRANTY
+
+**11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+**12.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

+owner that is granting the License.
+
+“Legal Entity” shall mean the union of the acting entity and all other entities
+that control, are controlled by, or are under common control with that entity.
+For the purposes of this definition, “control” means **(i)** the power, direct or
+indirect, to cause the direction or management of such entity, whether by
+contract or otherwise, or **(ii)** ownership of fifty percent (50%) or more of the
+outstanding shares, or **(iii)** beneficial ownership of such entity.
+
+“You” (or “Your”) shall mean an individual or Legal Entity exercising
+permissions granted by this License.

+“Source” form shall mean the preferred form for making modifications, including
+but not limited to software source code, documentation source, and configuration
+files.
+
+“Object” form shall mean any form resulting from mechanical transformation or
+translation of a Source form, including but not limited to compiled object code,
+generated documentation, and conversions to other media types.
+
+“Work” shall mean the work of authorship, whether in Source or Object form, made
+available under the License, as indicated by a copyright notice that is included
+in or attached to the work (an example is provided in the Appendix below).
+
+“Derivative Works” shall mean any work, whether in Source or Object form, that
+is based on (or derived from) the Work and for which the editorial revisions,
+annotations, elaborations, or other modifications represent, as a whole, an
+original work of authorship. For the purposes of this License, Derivative Works
+shall not include works that remain separable from, or merely link (or bind by
+name) to the interfaces of, the Work and Derivative Works thereof.
+
+“Contribution” shall mean any work of authorship, including the original version
+of the Work and any modifications or additions to that Work or Derivative Works
+thereof, that is intentionally submitted to Licensor for inclusion in the Work

+on behalf of the copyright owner. For the purposes of this definition,
+“submitted” means any form of electronic, verbal, or written communication sent
+to the Licensor or its representatives, including but not limited to
+communication on electronic mailing lists, source code control systems, and
+issue tracking systems that are managed by, or on behalf of, the Licensor for

+that is conspicuously marked or otherwise designated in writing by the copyright
+owner as “Not a Contribution.”
+
+“Contributor” shall mean Licensor and any individual or Legal Entity on behalf
+of whom a Contribution has been received by Licensor and subsequently
+incorporated within the Work.
+
+#### 2. Grant of Copyright License
+
+Subject to the terms and conditions of this License, each Contributor hereby
+grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
+irrevocable copyright license to reproduce, prepare Derivative Works of,
+publicly display, publicly perform, sublicense, and distribute the Work and such
+Derivative Works in Source or Object form.
+
+#### 3. Grant of Patent License
+
+Subject to the terms and conditions of this License, each Contributor hereby
+grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
+irrevocable (except as stated in this section) patent license to make, have
+made, use, offer to sell, sell, import, and otherwise transfer the Work, where
+such license applies only to those patent claims licensable by such Contributor
+that are necessarily infringed by their Contribution(s) alone or by combination
+of their Contribution(s) with the Work to which such Contribution(s) was
+submitted. If You institute patent litigation against any entity (including a
+cross-claim or counterclaim in a lawsuit) alleging that the Work or a
+Contribution incorporated within the Work constitutes direct or contributory
+patent infringement, then any patent licenses granted to You under this License
+for that Work shall terminate as of the date such litigation is filed.
+
+#### 4. Redistribution
+
+You may reproduce and distribute copies of the Work or Derivative Works thereof
+in any medium, with or without modifications, and in Source or Object form,
+provided that You meet the following conditions:
+
+* **(a)** You must give any other recipients of the Work or Derivative Works a
+copy of this License; and
+* **(b)** You must cause any modified files to carry prominent notices stating
+that You changed the files; and
+* **(c)** You must retain, in the Source form of any Derivative Works that You
+distribute, all copyright, patent, trademark, and attribution notices from the
+Source form of the Work, excluding those notices that do not pertain to any part
+of the Derivative Works; and
+* **(d)** If the Work includes a “NOTICE” text file as part of its distribution,
+then any Derivative Works that You distribute must include a readable copy of the
+attribution notices contained within such NOTICE file, excluding those notices
+that do not pertain to any part of the Derivative Works, in at least one of the
+following places: within a NOTICE text file distributed as part of the
+Derivative Works; within the Source form or documentation, if provided along
+with the Derivative Works; or, within a display generated by the Derivative
+Works, if and wherever such third-party notices normally appear. The contents of
+the NOTICE file are for informational purposes only and do not modify the
+License. You may add Your own attribution notices within Derivative Works that
+You distribute, alongside or as an addendum to the NOTICE text from the Work,
+provided that such additional attribution notices cannot be construed as
+modifying the License.
+
+You may add Your own copyright statement to Your modifications and may provide
+additional or different license terms and conditions for use, reproduction, or
+distribution of Your modifications, or for any such Derivative Works as a whole,
+provided Your use, reproduction, and distribution of the Work otherwise complies
+with the conditions stated in this License.
+
+#### 5. Submission of Contributions
+
+Unless You explicitly state otherwise, any Contribution intentionally submitted
+for inclusion in the Work by You to the Licensor shall be under the terms and
+conditions of this License, without any additional terms or conditions.
+Notwithstanding the above, nothing herein shall supersede or modify the terms of
+any separate license agreement you may have executed with Licensor regarding
+such Contributions.
+
+#### 6. Trademarks
+
+This License does not grant permission to use the trade names, trademarks,
+service marks, or product names of the Licensor, except as required for
+reasonable and customary use in describing the origin of the Work and
+reproducing the content of the NOTICE file.
+
+#### 7. Disclaimer of Warranty
+
+Unless required by applicable law or agreed to in writing, Licensor provides the
+Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
+WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
+including, without limitation, any warranties or conditions of TITLE,
+NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
+solely responsible for determining the appropriateness of using or
+redistributing the Work and assume any risks associated with Your exercise of
+permissions under this License.
+
+#### 8. Limitation of Liability
+
+In no event and under no legal theory, whether in tort (including negligence),
+contract, or otherwise, unless required by applicable law (such as deliberate
+and grossly negligent acts) or agreed to in writing, shall any Contributor be
+liable to You for damages, including any direct, indirect, special, incidental,
+or consequential damages of any character arising as a result of this License or
+out of the use or inability to use the Work (including but not limited to
+damages for loss of goodwill, work stoppage, computer failure or malfunction, or
+any and all other commercial damages or losses), even if such Contributor has
+been advised of the possibility of such damages.
+
+#### 9. Accepting Warranty or Additional Liability
+
+While redistributing the Work or Derivative Works thereof, You may choose to
+offer, and charge a fee for, acceptance of support, warranty, indemnity, or
+other liability obligations and/or rights consistent with this License. However,
+in accepting such obligations, You may act only on Your own behalf and on Your
+sole responsibility, not on behalf of any other Contributor, and only if You
+agree to indemnify, defend, and hold each Contributor harmless for any liability
+incurred by, or claims asserted against, such Contributor by reason of your
+accepting any such warranty or additional liability.

+### Section 2 – Scope.
+
+a. ___License grant.___
+
+    1. Subject to the terms and conditions of this Public License, the Licensor
+       hereby grants You a worldwide, royalty-free, non-sublicensable,
+       non-exclusive, irrevocable license to exercise the Licensed Rights in the
+       Licensed Material to:
+
+        A. reproduce and Share the Licensed Material, in whole or in part; and
+
+        B. produce, reproduce, and Share Adapted Material.
+
+    2. __Exceptions and Limitations.__ For the avoidance of doubt, where
+       Exceptions and Limitations apply to Your use, this Public License does
+       not apply, and You do not need to comply with its terms and conditions.
+
+    3. __Term.__ The term of this Public License is specified in Section 6(a).
+
+    4. __Media and formats; technical modifications allowed.__ The Licensor
+       authorizes You to exercise the Licensed Rights in all media and formats
+       whether now known or hereafter created, and to make technical
+       modifications necessary to do so. The Licensor waives and/or agrees not
+       to assert any right or authority to forbid You from making technical
+       modifications necessary to exercise the Licensed Rights, including
+       technical modifications necessary to circumvent Effective Technological
+       Measures. For purposes of this Public License, simply making
+       modifications authorized by this Section 2(a)(4) never produces Adapted
+       Material.
+
+    5. __Downstream recipients.__
+
+        A. __Offer from the Licensor – Licensed Material.__ Every recipient of
+           the Licensed Material automatically receives an offer from the
+           Licensor to exercise the Licensed Rights under the terms and
+           conditions of this Public License.
+
+        B. __No downstream restrictions.__ You may not offer or impose any
+           additional or different terms or conditions on, or apply any
+           Effective Technological Measures to, the Licensed Material if doing
+           so restricts exercise of the Licensed Rights by any recipient of the
+           Licensed Material.
+
+    6. __No endorsement.__ Nothing in this Public License constitutes or may be
+       construed as permission to assert or imply that You are, or that Your use
+       of the Licensed Material is, connected with, or sponsored, endorsed, or
+       granted official status by, the Licensor or others designated to receive
+       attribution as provided in Section 3(a)(1)(A)(i).
+
+b. ___Other rights.___
+
+    1. Moral rights, such as the right of integrity, are not licensed under this
+       Public License, nor are publicity, privacy, and/or other similar
+       personality rights; however, to the extent possible, the Licensor waives
+       and/or agrees not to assert any such rights held by the Licensor to the
+       limited extent necessary to allow You to exercise the Licensed Rights,
+       but not otherwise.
+
+    2. Patent and trademark rights are not licensed under this Public License.
+
+    3. To the extent possible, the Licensor waives any right to collect
+       royalties from You for the exercise of the Licensed Rights, whether
+       directly or through a collecting society under any voluntary or waivable
+       statutory or compulsory licensing scheme. In all other cases the Licensor
+       expressly reserves any right to collect such royalties.
+
+### Section 3 – License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the following
+conditions.
+
+a. ___Attribution.___
+
+    1. If You Share the Licensed Material (including in modified form), You must:
+
+        A. retain the following if it is supplied by the Licensor with the
+           Licensed Material:
+
+            i. identification of the creator(s) of the Licensed Material and any
+               others designated to receive attribution, in any reasonable
+               manner requested by the Licensor (including by pseudonym if
+               designated);
+
+            ii. a copyright notice;
+
+            iii. a notice that refers to this Public License;
+
+            iv. a notice that refers to the disclaimer of warranties;
+
+            v. a URI or hyperlink to the Licensed Material to the extent
+               reasonably practicable;
+
+        B. indicate if You modified the Licensed Material and retain an
+           indication of any previous modifications; and
+
+        C. indicate the Licensed Material is licensed under this Public License,
+           and include the text of, or the URI or hyperlink to, this Public
+           License.
+
+    2. You may satisfy the conditions in Section 3(a)(1) in any reasonable
+       manner based on the medium, means, and context in which You Share the
+       Licensed Material. For example, it may be reasonable to satisfy the
+       conditions by providing a URI or hyperlink to a resource that includes
+       the required information.
+
+    3. If requested by the Licensor, You must remove any of the information
+       required by Section 3(a)(1)(A) to the extent reasonably practicable.
+
+    4. If You Share Adapted Material You produce, the Adapter's License You
+       apply must not prevent recipients of the Adapted Material from complying
+       with this Public License.
+
+### Section 4 – Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that apply to Your
+use of the Licensed Material:
+
+a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
+   reuse, reproduce, and Share all or a substantial portion of the contents of
+   the database;
+
+b. if You include all or a substantial portion of the database contents in a
+   database in which You have Sui Generis Database Rights, then the database in
+   which You have Sui Generis Database Rights (but not its individual contents)
+   is Adapted Material; and
+
+c. You must comply with the conditions in Section 3(a) if You Share all or a
+   substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not replace Your
+obligations under this Public License where the Licensed Rights include other
+Copyright and Similar Rights.
+
+### Section 5 – Disclaimer of Warranties and Limitation of Liability.
+
+a. __Unless otherwise separately undertaken by the Licensor, to the extent
+   possible, the Licensor offers the Licensed Material as-is and as-available,
+   and makes no representations or warranties of any kind concerning the
+   Licensed Material, whether express, implied, statutory, or other. This
+   includes, without limitation, warranties of title, merchantability, fitness
+   for a particular purpose, non-infringement, absence of latent or other
+   defects, accuracy, or the presence or absence of errors, whether or not known
+   or discoverable. Where disclaimers of warranties are not allowed in full or
+   in part, this disclaimer may not apply to You.__
+
+b. __To the extent possible, in no event will the Licensor be liable to You on
+   any legal theory (including, without limitation, negligence) or otherwise for
+   any direct, special, indirect, incidental, consequential, punitive,
+   exemplary, or other losses, costs, expenses, or damages arising out of this
+   Public License or use of the Licensed Material, even if the Licensor has been
+   advised of the possibility of such losses, costs, expenses, or damages. Where
+   a limitation of liability is not allowed in full or in part, this limitation
+   may not apply to You.__
+
+c. The disclaimer of warranties and limitation of liability provided above shall
+   be interpreted in a manner that, to the extent possible, most closely
+   approximates an absolute disclaimer and waiver of all liability.
+
+### Section 6 – Term and Termination.
+
+a. This Public License applies for the term of the Copyright and Similar Rights
+   licensed here. However, if You fail to comply with this Public License, then
+   Your rights under this Public License terminate automatically.
+
+b. Where Your right to use the Licensed Material has terminated under Section
+   6(a), it reinstates:
+
+    1. automatically as of the date the violation is cured, provided it is cured
+       within 30 days of Your discovery of the violation; or
+
+    2. upon express reinstatement by the Licensor.
+
+    For the avoidance of doubt, this Section 6(b) does not affect any right the
+    Licensor may have to seek remedies for Your violations of this Public
+    License.
+
+c. For the avoidance of doubt, the Licensor may also offer the Licensed Material
+   under separate terms or conditions or stop distributing the Licensed Material
+   at any time; however, doing so will not terminate this Public License.
+
+d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
+
+### Section 7 – Other Terms and Conditions.
+
+a. The Licensor shall not be bound by any additional or different terms or
+   conditions communicated by You unless expressly agreed.
+
+b. Any arrangements, understandings, or agreements regarding the Licensed
+   Material not stated herein are separate from and independent of the terms and
+   conditions of this Public License.
+
+### Section 8 – Interpretation.
+
+a. For the avoidance of doubt, this Public License does not, and shall not be
+   interpreted to, reduce, limit, restrict, or impose conditions on any use of
+   the Licensed Material that could lawfully be made without permission under
+   this Public License.
+
+b. To the extent possible, if any provision of this Public License is deemed
+   unenforceable, it shall be automatically reformed to the minimum extent
+   necessary to make it enforceable. If the provision cannot be reformed, it
+   shall be severed from this Public License without affecting the
+   enforceability of the remaining terms and conditions.
+
+c. No term or condition of this Public License will be waived and no failure to
+   comply consented to unless expressly agreed to by the Licensor.
+
+d. Nothing in this Public License constitutes or may be interpreted as a
+   limitation upon, or waiver of, any privileges and immunities that apply to
+   the Licensor or You, including from the legal processes of any jurisdiction
+   or authority.

-------------------------------------------------------------------------------
+This is a fork of ZeroBin, originally developed by
+[Sébastien Sauvage](https://github.com/sebsauvage/ZeroBin). It was refactored
+to allow easier and cleaner extensions and has now much more features than the
+original. It is however still fully compatible to the original ZeroBin 0.19
+data storage scheme. Therefore such installations can be upgraded to this fork
+without loosing any data.
 
-Copyright (c) 2012 Sébastien SAUVAGE (sebsauvage.net)
+## What PrivateBin provides
 
-This software is provided 'as-is', without any express or implied warranty.
-In no event will the authors be held liable for any damages arising from 
-the use of this software.
++ As a server administrator you don't have to worry if your users post content
+  that is considered illegal in your country. You have no knowledge of any
+  of the pastes content. If requested or enforced, you can delete any paste from
+  your system.
 
-Permission is granted to anyone to use this software for any purpose, 
-including commercial applications, and to alter it and redistribute it 
-freely, subject to the following restrictions:
++ Pastebin-like system to store text documents, code samples, etc.
 
-    1. The origin of this software must not be misrepresented; you must 
-       not claim that you wrote the original software. If you use this 
-       software in a product, an acknowledgment in the product documentation
-       would be appreciated but is not required.
++ Encryption of data sent to server.
 
-    2. Altered source versions must be plainly marked as such, and must 
-       not be misrepresented as being the original software.
++ Possibility to set a password which is required to read the paste. It further
+  protects a paste and prevents people stumbling upon your paste's link
+  from being able to read it without the password.
 
-    3. This notice may not be removed or altered from any source distribution.
+## What it doesn't provide
 
-------------------------------------------------------------------------------
+- As a user you have to trust the server administrator, your internet provider
+  and any country the traffic passes not to inject any malicious javascript code.
+  For a basic security the PrivateBin installation *has to provide HTTPS*!
+  Additionally it should be secured by
+  [HSTS](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) and
+  ideally by [HPKP](https://en.wikipedia.org/wiki/HTTP_Public_Key_Pinning) using a
+  certificate either validated by a trusted third party (check the certificate
+  when first using a new PrivateBin instance) or self-signed by the server
+  operator, validated using a
+  [DNSSEC](https://en.wikipedia.org/wiki/Domain_Name_System_Security_Extensions)
+  protected
+  [DANE](https://en.wikipedia.org/wiki/DNS-based_Authentication_of_Named_Entities)
+  record.
+
+- The "key" used to encrypt the paste is part of the URL. If you publicly post
+  the URL of a paste that is not password-protected, everybody can read it.
+  Use a password if you want your paste to be private. In this case make sure to
+  use a strong password and do only share it privately and end-to-end-encrypted.
+
+- A server admin might be forced to hand over access logs to the authorities.
+  PrivateBin encrypts your text and the discussion contents, but who accessed it
+  first might still be disclosed via such access logs.
+
+- In case of a server breach your data is secure as it is only stored encrypted
+  on the server. However the server could be misused or the server admin could
+  be legally forced into sending malicious JavaScript to all web users, which
+  grabs the decryption key and send it to the server when a user accesses a
+  PrivateBin.  
+  Therefore do not access any PrivateBin instance if you think it has been
+  compromised. As long as no user accesses this instance with a previously
+  generated URL, the content can''t be decrypted.
+
+## Options
+
+Some features are optional and can be enabled or disabled in the [configuration
+file](https://github.com/PrivateBin/PrivateBin/wiki/Configuration):
+
+* Password protection
+
+* Discussions, anonymous or with nicknames and IP based identicons or vizhashes
+
+* Expiration times, including a "forever" and "burn after reading" option
+
+* Markdown format support for HTML formatted pastes, including preview function
+
+* Syntax highlighting for source code using prettify.js, including 4 prettify
+  themes
+
+* File upload support, images get displayed (disabled by default, possibility
+  to adjust size limit)
+
+* Templates: By default there are bootstrap CSS, darkstrap and "classic ZeroBin"
+  themes and it is easy to adapt these to your own websites layout or create
+  your own.
+
+* Translation system and automatic browser language detection (if enabled in
+  browser)
+
+* Language selection (disabled by default, as it uses a session cookie)

+Generating documentation
+========================
+
+In order to generate the documentation, you will need to install the following
+packages and its dependencies:
+* phpdoc
+* graphviz
+
+Details about
+[installing phpDocumentor](https://phpdoc.org/docs/latest/getting-started/installing.html)
+can be found in that projects documentation.
+
+Example for Debian and Ubuntu:
+```console
+$ sudo aptitude install php-pear graphviz
+$ sudo pear channel-discover pear.phpdoc.org
+$ sudo pear install phpdoc/phpDocumentor
+```
+
+To generate the documentation, change into the main directory and run phpdoc:
+```console
+$ cd PrivateBin
+$ phpdoc -d lib/ -t doc/
+```
+
+**Note:** When used with PHP 7, the prerelease of phpDocumentator 2.9 needs to be
+manually installed by downloading it from
+[GitHub](https://github.com/phpDocumentor/phpDocumentor2/releases/download/v2.9.0/phpDocumentor.phar)
+and then manually moving it to e.g. `/usr/local/bin` and making it executable.
