Are dms e2e encrypted between recipients? (lemmy.ml)

Just curious if that is the case. I assume not as Lemmy does not advertise it's encryption at all.

Would this ever be planned for Lemmy?

Implementing E2E isn't just about the encryption though, it's also about the key exchange/distribution/generation approach.

If you look at what Matrix does, so much of the complexity comes from how they authenticate all the different clients to manage E2E in a distributed way. For proper E2E you've got more than 2 ends (multiple clients) so you need to manage it for all.

I don't get what makes it hard to implement the same stuff using libraries provided, encryption should be optional for servers administrators to enable

Encryption is hard to get right. Which doesn't help when it's essentially useless unless you get it right

https://github.com/soatok/mastodon-e2ee-specification was a thing but it doesn't seem to be updated for months now.
