CryptPad is the **Zero Knowledge** realtime collaborative editor.
|
|
|
|
Encryption carried out in your web browser protects the data from the server, the cloud
|
|
and the NSA. It relies on the [ChainPad] realtime engine.
|

# Installation
|
|
|
|
Installing CryptPad is pretty straightforward. You can read all about it in the
|
|
[installation guide](https://github.com/xwiki-labs/cryptpad/wiki/Installation-guide).
|
|
|
|
It also contains information on keeping your instance of CryptPad up to date.
|
|
|
|
## Current version
|
|
|
|
The most recent version and all past release notes can be found [here](https://github.com/xwiki-labs/cryptpad/releases/).
|
|
|
|
## Setup using Docker
|
|
|
|
See [Cryptpad-Docker](https://github.com/xwiki-labs/cryptpad-docker) repository for details on how to get up-and-running with Cryptpad in Docker. This repository is maintained by the community and not officially supported.

# Security
|
|
|
|
CryptPad is *private*, not *anonymous*. Privacy protects your data, anonymity protects you.
|
|
As such, it is possible for a collaborator on the pad to include some silly/ugly/nasty things
|
|
in a CryptPad such as an image which reveals your IP address when your browser automatically
|
|
loads it or a script which plays Rick Astleys's greatest hits. It is possible for anyone
|
|
who does not have the key to be able to change anything in the pad or add anything, even the
|
|
server, however the clients will notice this because the content hashes in CryptPad will fail to
|
|
validate.
|
|
|
|
The server does have a certain power, it can send you evil javascript which does the wrong
|
|
thing (leaks the key or the data back to the server or to someone else). This is however an
|
|
[active attack] which makes it detectable. The NSA really hates doing these because they might
|
|
get caught and laughed at and humiliated in front of the whole world (again). If you're making
|
|
the NSA mad enough for them to use an active attack against you, Great Success Highfive, now take
|
|
the battery out of your computer before it spawns Agent Smith.
|
|
|
|
Still there are other low-lives in the world so using CryptPad over HTTPS is probably a good idea.

# Translations
|
|
|
|
We'd like to make it easy for more people to use encryption in their routine activities.
|
|
As such, we've tried to make language-specific parts of CryptPad translatable. If you're
|
|
able to translate CryptPad's interface, and would like to help, please contact us!
|
|
|
|
You can also see [our translation guide](/customize.dist/translations/README.md).
