* 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: "5 minutes" and "1 week" expirations.
* ADDED: "Raw text" button.
* jQuery upgraded to 1.9.1
* sjcl upgraded to GitHub master 2013-02-23
* base64.js upgraded to 1.7
* FIXED: Dates in discussion are now proper local dates.
* ADDED: Robot meta tags in HTML to prevent search engines indexing.
* 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 0.17 (2013-02-23)**:
* ADDED: Deletion URL.
* small refactoring.
* improved regex checks.
* larger server alt on installation.
* **Alpha 0.16**:
* 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 0.15 (2012-04-20):**
* FIXED: 2 minor corrections to avoid notices in php log.
* FIXED: Sources converted to UTF-8.
* **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 0.13 (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 0.12 (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 0.11 (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 0.10 (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 0.9 (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 0.8 (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
**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.
**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.
### Minimal requirements
- PHP version 5.5 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 full path of PrivateBin on your webserver is:
> /home/example.com/htdocs/paste
>
> When setting the path like this:
> define('PATH', '../../secret/privatebin/');
>
> PrivateBin will look for your includes / data here:
> /home/example.com/secret/privatebin
### Changing the config path only
In situations where you want to keep the PrivateBin static files separate from the
rest of your data, or you want to reuse the installation files on multiple vhosts,
you may only want to change the `conf.php`. In this instance, you can set the
`CONFIG_PATH` environment variable to the absolute path to the `conf.php` file.
This can be done in your web server's virtual host config, the PHP config, or in
the index.php if you choose to customize it.
Note that your PHP process will need read access to the config wherever it may be.
> #### CONFIG_PATH example
> Setting the value in an Apache Vhost:
> SetEnv CONFIG_PATH /var/lib/privatebin/conf.php
>
> In a php-fpm pool config:
> env[CONFIG_PATH] = /var/lib/privatebin/conf.php
>
> In the index.php, near the top:
> putenv('CONFIG_PATH=/var/lib/privatebin/conf.php');
### Transport security
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).
### File-level permissions
After completing the installation, you should make sure, other users on the system cannot read the config file or the `data/` directory, as – depending on your configuration – potential secret information are saved there.
See [this FAQ item](https://github.com/PrivateBin/PrivateBin/wiki/FAQ#what-are-the-recommended-file-and-folder-permissions-for-privatebin) for a detailed guide on how to "harden" the permissions of files and folders.
## Configuration
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. Alternatively you can copy it anywhere and
set the `CONFIG_PATH` environment variable (see above notes). 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 PrivateBin installation.
More details can be found in the
[configuration documentation](https://github.com/PrivateBin/PrivateBin/wiki/Configuration).
## 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.
### When 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.
The following GRANTs (privileges) are required for the PrivateBin user in **MySQL**. In normal operation:
- INSERT, SELECT, DELETE on the paste and comment tables
- SELECT on the config table
If you want PrivateBin to handle table creation (when you create the first paste) and updates (after you update PrivateBin to a new release), you need to give the user these additional privileges:
- CREATE, INDEX and ALTER on the database
- INSERT and UPDATE on the config table
For reference or if you want to create the table schema for yourself to avoid having to give PrivateBin too many permissions (replace
`prefix_` with your own table prefix and create the table schema with your favourite MySQL console):
```sql
CREATE TABLE prefix_paste (
dataid CHAR(16) NOT NULL,
data MEDIUMBLOB,
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', '1.3.2');
```
In **PostgreSQL**, the data, attachment, nickname and vizhash columns needs to be TEXT and not BLOB or MEDIUMBLOB.

## GNU General Public License, version 2.0, for rawinflate
_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.

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

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

By exercising the Licensed Rights (defined below), You accept and agree to be
bound by the terms and conditions of this Creative Commons Attribution 4.0
International Public License ("Public License"). To the extent this Public
License may be interpreted as a contract, You are granted the Licensed Rights in
consideration of Your acceptance of these terms and conditions, and the Licensor
grants You such rights in consideration of benefits the Licensor receives from
making the Licensed Material available under these terms and conditions.
### Section 1 – Definitions.
a. __Adapted Material__ means material subject to Copyright and Similar Rights
that is derived from or based upon the Licensed Material and in which the
Licensed Material is translated, altered, arranged, transformed, or otherwise
modified in a manner requiring permission under the Copyright and Similar Rights
held by the Licensor. For purposes of this Public License, where the Licensed
Material is a musical work, performance, or sound recording, Adapted Material is
always produced where the Licensed Material is synched in timed relation with a
moving image.
b. __Adapter's License__ means the license You apply to Your Copyright and
Similar Rights in Your contributions to Adapted Material in accordance with the
terms and conditions of this Public License.
c. __Copyright and Similar Rights__ means copyright and/or similar rights
closely related to copyright including, without limitation, performance,
broadcast, sound recording, and Sui Generis Database Rights, without regard to
how the rights are labeled or categorized. For purposes of this Public License,
the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
d. __Effective Technological Measures__ means those measures that, in the
absence of proper authority, may not be circumvented under laws fulfilling
obligations under Article 11 of the WIPO Copyright Treaty adopted on December
20, 1996, and/or similar international agreements.
e. __Exceptions and Limitations__ means fair use, fair dealing, and/or any other
exception or limitation to Copyright and Similar Rights that applies to Your use
of the Licensed Material.
f. __Licensed Material__ means the artistic or literary work, database, or other
material to which the Licensor applied this Public License.
g. __Licensed Rights__ means the rights granted to You subject to the terms and
conditions of this Public License, which are limited to all Copyright and
Similar Rights that apply to Your use of the Licensed Material and that the
Licensor has authority to license.
h. __Licensor__ means the individual(s) or entity(ies) granting rights under
this Public License.
i. __Share__ means to provide material to the public by any means or process
that requires permission under the Licensed Rights, such as reproduction, public
display, public performance, distribution, dissemination, communication, or
importation, and to make material available to the public including in ways that
members of the public may access the material from a place and at a time
individually chosen by them.
j. __Sui Generis Database Rights__ means rights other than copyright resulting
from Directive 96/9/EC of the European Parliament and of the Council of 11 March
1996 on the legal protection of databases, as amended and/or succeeded, as well
as other essentially equivalent rights anywhere in the world.
k. __You__ means the individual or entity exercising the Licensed Rights under
this Public License. Your has a corresponding meaning.
### 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

# [![PrivateBin](https://cdn.rawgit.com/PrivateBin/assets/master/images/preview/logoSmall.png)](https://privatebin.info/)
*Current version: 1.3.2*
**PrivateBin** is a minimalist, open source online [pastebin](https://en.wikipedia.org/wiki/Pastebin)
where the server has zero knowledge of pasted data.
Data is encrypted and decrypted in the browser using 256bit AES in [Galois Counter mode](https://en.wikipedia.org/wiki/Galois/Counter_Mode).
This is a fork of ZeroBin, originally developed by
[Sébastien Sauvage](https://github.com/sebsauvage/ZeroBin). ZeroBin was refactored
to allow easier and cleaner extensions. PrivateBin has many more features than the
original ZeroBin. It is, however, still fully compatible to the original ZeroBin 0.19
data storage scheme. Therefore, such installations can be upgraded to PrivateBin
without losing any data.
## What PrivateBin provides
+ 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.
+ Pastebin-like system to store text documents, code samples, etc.
+ Encryption of data sent to server.
+ 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.
## What it doesn't provide
- As a user you have to trust the server administrator not to inject any malicious
javascript code.
For basic security, the PrivateBin installation *has to provide HTTPS*!
Otherwise you would also have to trust your internet provider, and any country
the traffic passes through.
Additionally the instance 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. It can use traditional certificate authorities and/or use
[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, anyone 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 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 a
paste (first) might still be disclosed via 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 sends 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"
to choose from 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)
* QR code generation of URL, to easily transfer pastes over to a mobile device

; which display mode to preselect by default, defaults to "plaintext"
; make sure the value exists in [formatter_options]
defaultformatter = "plaintext"
; (optional) set a syntax highlighting theme, as found in css/prettify/
; syntaxhighlightingtheme = "sons-of-obsidian"
; size limit per paste or comment in bytes, defaults to 10 Mebibytes
sizelimit = 10485760
; template to include, default is "bootstrap" (tpl/bootstrap.php)
template = "bootstrap"
; (optional) notice to display
; notice = "Note: This is a test service: Data may be deleted anytime. Kittens will die if you abuse this service."
; by default PrivateBin will guess the visitors language based on the browsers
; settings. Optionally you can enable the language selection menu, which uses
; a session cookie to store the choice until the browser is closed.
languageselection = false
; set the language your installs defaults to, defaults to English
; if this is set and language selection is disabled, this will be the only language
; languagedefault = "en"
; (optional) URL shortener address to offer after a new paste is created
; it is suggested to only use this with self-hosted shorteners as this will leak
; the pastes encryption key
; urlshortener = "https://shortener.example.com/api?link="
; (optional) Let users create a QR code for sharing the paste URL with one click.
; It works both when a new paste is created and when you view a paste.
; qrcode = true
; (optional) IP based icons are a weak mechanism to detect if a comment was from
; a different user when the same username was used in a comment. It might be
; used to get the IP of a non anonymous comment poster if the server salt is
; leaked and a SHA256 HMAC rainbow table is generated for all (relevant) IPs.
; Can be set to one these values: "none" / "vizhash" / "identicon" (default).
; icon = "none"
; Content Security Policy headers allow a website to restrict what sources are
; allowed to be accessed in its context. You need to change this if you added
; custom scripts from third-party domains to your templates, e.g. tracking
; scripts or run your site behind certain DDoS-protection services.
; Check the documentation at https://content-security-policy.com/
; Notes:
; - If you use a bootstrap theme, you can remove the allow-popups from the
; sandbox restrictions.
; - By default this disallows to load images from third-party servers, e.g. when
; they are embedded in pastes. If you wish to allow that, you can adjust the
; policy here. See https://github.com/PrivateBin/PrivateBin/wiki/FAQ#why-does-not-it-load-embedded-images
; for details.
; - The 'unsafe-eval' is used in two cases; to check if the browser supports
; async functions and display an error if not and for Chrome to enable
; webassembly support (used for zlib compression). You can remove it if Chrome
; doesn't need to be supported and old browsers don't need to be warned.
