2022-07-04, 14:15–14:50 (Europe/Paris), Amphitheater

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

This talk will include:

  • 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: . You can also read a blog post about it here: .

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