Cryptpad Uberspace Guide

This guide was written for UberLab by me. This is just a copy but maybe it is more up-to-date due to the fact that is's easier for me to update this site, than the UberLab. I am trying to keep both side up-to-date.


Cryptpad is a Zero Knowledge realtime collaborative editor. It is based on Node.js and comes with encryption. It relies on the ChainPad.


For this guide you need some tools:


Set up the backends:

[isabell@stardust ~]$ uberspace web backend set / --http --port 3000
Set backend for / to port 3000; please make sure something is listening!You can always check the status of your backend using "uberspace web backend list".

Now let's get started with Cryptpad.

We're using Node.js in the stable version 10:

[isabell@stardust ~]$ uberspace tools version use node 10
Selected Node.js version 10

We also need Bower:

[isabell@stardust ~]$ npm install -g bower


Start with cloning the Cryptpad source code from Github and be sure to replace the branch 2.21.0 with the current release number from the feed:

[isabell@stardust ~]$ git clone --branch 2.21.0

You are in 'detached HEAD' state. You can look around, make experimentalchanges and commit them, and you can discard any commits you make in thisstate without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you maydo so (now or later) by using -b with the checkout command again. Example:

git checkout -b

Checking out files: 100% (4319/4319), done.

Now we need to install some dependencies:

[isabell@stardust ~]$ cd ~/cryptpad
[isabell@stardust cryptpad]$ npm install
added 168 packages from 186 contributors and audited 311 packages in 14.352s
found 0 vulnerabilities
[isabell@stardust cryptpad]$ bower install
bower install       open-sans-fontface#1.4.2
bower install       jquery#2.1.4
bower install       bootstrap#4.3.1


[isabell@stardust cryptpad]$ cp config/config.example.js config/config.js

Edit config/config.js and change the value of the variable _domain to your domain, like so:

globals module
var _domain = '';

Setup daemon

Create ~/etc/services.d/cryptpad.ini with the following content:

command=node server

Now let's start the service:

After creating the configuration, tell supervisord to refresh its configuration and start the service:

[isabell@stardust ~]$ supervisorctl reread
SERVICE: available
[isabell@stardust ~]$ supervisorctl update
SERVICE: added process group
[isabell@stardust ~]$ supervisorctl status
cryptpad                            RUNNING   pid 26020, uptime 0:03:14

The dashboard once you are logged in


For any further configuration or customization you should have a look at the Cryptpad Wiki.


Check the update feed regularly to stay informed about the newest version

If there is a new version available, you can get the code using git. Replace the version number 2.19.0 with the latest version number you got from the release feed:

[isabell@stardust ~]$ cd ~/cryptpad
[isabell@stardust cryptpad]$ git pull origin 2.19.0

tag                 2.19.0     -> FETCH_HEADAlready up to date.

Then you need to restart the service, so the new code is used by the webserver:

[isabell@stardust cryptpad]$ supervisorctl restart cryptpad

Last tested: with Cryptpad 2.24.0 and Uberspace
