Setting up encryption
Draupnir can still protect encrypted rooms without an E2EE capable device. Please see protecting encrypted rooms here.
We can not at this time recommend setting up Draupnir with an E2EE capable device - neither with Pantalaimon or the rust crypto.
Historically there have been two options for providing an E2EE capable device to Draupnir: Pantalaimon and the matrix-bot-sdk's experimental rust crypto. Neither of these options are of a high enough quality.
While we have previously permitted the use of Pantaliamon, it has consistently confused beginners that are setting it up with Draupnir, and we do not use it ourselves. Experienced system admins are welcome to attempt to set up Pantalaimon, but must be aware that any issues that they experience getting Draupnir to start are extremely likely to be from the Pantalaimon configuration and not Draupnir itself. Additionally, there are a couple of known bugs that inhibit the use of reactions in the management room when using Pantalaimon. Which are a core part of Draupnir's UX rework.
You can find indiviual keys in Draupnir's configuration relating to both the matrix-bot-sdk and Pantalaimon.
