*Current version: 1.1.1*

**PrivateBin** is a minimalist, open source online 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"
  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)
