ZeroBin 0.22
ZeroBin is a minimalist, opensource online pastebin where the server has zero knowledge of pasted data.
Data is encrypted/decrypted in the browser using 256 bit AES.
This fork of ZeroBin refactored the source code to allow easier and cleaner extensions. It is 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.
What ZeroBin 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, even if it does not provide HTTPS.
-
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, your internet provider and any country the traffic passes not to inject any malicious javascript code. Ideally, the ZeroBin installation used would provide HTTPS, secured by HSTS and HPKP using a certificate either validated by a trusted third party (check the certificate when first using a new ZeroBin instance) or self-signed by the server operator, validated using a DNSSEC protected DANE 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.
-
A server admin might be forced to hand over access logs to the authorities. ZeroBin encrypts your text and the discussion contents, but who accessed it first might still be disclosed via such access logs.
