|
|
*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.
|
|
|
|
