This talk will describe the internals of a Mattermost End-to-End Encryption plugin that has been developed at Quarkslab in 2021.

 

This talk includes:

  • the problems we are trying to solve, and the attack models considered
  • existing plugins / why make a new one
  • the underlying cryptography protocol and various tradeoff
  • maybe a small demo :)

The plugin is open source here: https://github.com/quarkslab/mattermost-plugin-e2ee .

You can also read a blog post about it here: https://blog.quarkslab.com/mattermost-end-to-end-encryption-plugin.html .

It's been battle-tested and used (almost) seamlessly in production at Quarkslab since September 2021, within a team of around 100 people.
