Unity is Strength - Collaboration is Key
CryptPad is the **Zero Knowledge** realtime collaborative editor.

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. This project uses the [CKEditor] Visual Editor and the [ChainPad] realtime
engine. The secret key is stored in the URL [fragment identifier] which is never sent to
the server but is available to javascript so by sharing the URL, you give authorization
to others who want to participate.
and the NSA. It relies on the [ChainPad] realtime engine.

# Installation
Cryptpad depends on the Nodejs runtime.
We recommend installing it via [NVM](https://github.com/creationix/nvm "Node Version Manager") to ensure that you are running an up to date version.
Installing CryptPad is pretty straightforward. You can read all about it in the
[installation guide](https://github.com/xwiki-labs/cryptpad/wiki/Installation-guide).
Once you have a recent runtime (we use v6.6.0):
It also contains information on keeping your instance of CryptPad up to date.
```
git clone <this repo>
cd cryptpad
npm install
npm install -g bower ## if necessary
bower install
## Setup using Docker
## copy config.example.js to config.js
cp config.example.js config.js
See [Cryptpad-Docker](docs/cryptpad-docker.md)
node ./server.js
```
## Configuration
CryptPad _should_ work with an unmodified configuration file, though there are many things which you may want to customize.
Attributes in the config should have comments indicating how they are used.
```
$EDITOR config.js
```
If you are deploying CryptPad in a production environment, we recommend that you take the time to understand and correctly customize your server's [Content Security Policy headers](https://content-security-policy.com/).
Modern browsers use these headers to allow or deny actions from malicious clients which could compromise the confidentiality of your user's data.
These settings can be found in your configuration file in the `contentSecurity` and `padContentSecurity` sections.
## Maintenance
Before upgrading your CryptPad instance to the latest version, we recommend that you check what has changed since your last update.
You can do so by checking which version you have (see package.json), and comparing it against newer [release notes](https://github.com/xwiki-labs/cryptpad/releases).
To get access to the most recent codebase:
```
cd /your/cryptpad/instance/location;
git pull
```
To update dependencies:
```
# clientside dependencies
bower update;
# serverside dependencies
npm update;
```
## Deleting all data and resetting Cryptpad
To reset your instance of Cryptpad and remove all the data that is being stored:
**WARNING: This will reset your Cryptpad instance and remove all data**
```
# change into your cryptpad directory
cd /your/cryptpad/instance/location;
# delete the datastore
rm -rf ./datastore
```
If you are using the mongodb adaptor, [drop the relevant collection](https://docs.mongodb.org/manual/reference/method/db.collection.drop/#db.collection.drop).
If you are using the [leveldb adaptor](https://github.com/xwiki-labs/cryptpad-level-store), delete the datastore directory you have configured.
## Testing
To test CryptPad, go to http://your.server:3000/assert/
You can use WebDriver to run this test automatically by running TestSelenium.js but you will need chromedriver installed.
If you use Mac, you can `brew install chromedriver`.
## Developing CryptPad
CryptPad is built with a lot of small javascript libraries.
To make js files load faster, we apply an aggressive caching policy.
If you want to add new features to CryptPad, you'll want to turn off caching.
You can do so by launching your server in _dev mode_, like so:
`DEV=1 node server.js`
## Security
# 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
