CryptPad is a private-by-design encrypted collaborative editor for notes, documents, kanban boards, polls, whiteboards and more. It’s easy to access via your web browser, and uses 100% client-side encryption. This means that all files are stored encrypted so even we, as server administrators with full access to the hardware, cannot read the documents.

You can use Cryptpad to create collaborative documents for taking notes and writing down ideas together, and you can share access to each “pad” simply by sharing the link.

How we use CryptPad

We also use CryptPad ourselves, for notes shared between our team members and the organisations we support. For example:

  • debugging code snippets together
  • working through combinations of hardware driver, Linux kernel, and firmware versions to find stable combinations for Intel i40e X710-DA4 network cards, something we’ve had a lot of experience with!
  • project planning for our CVE-2018-19299 mitigation
  • documenting confidential technical information for customers, as part of their disaster recovery and business continuity plans

If you need to work with our sysadmin and support team and share sensitive information — such as configuration files or terminal sessions — we encourage you to do so using By using the features it provides we collaborate with you in real-time, and your confidential data is secure with end-to-end encryption.
