There are currently 2 specified e2ee mechanisms for pubsub: - XEP-0473: OpenPGP for XMPP Pubsub , this is probably what you want to use. - XEP-0477: Pubsub Targeted Encryption, this is more for ad-hoc item encryption, and can be used with OMEMO (so you can have PFS). But in your use case, I thing that XEP-0473 is more adapted (and probably easier to implement). Note that Libervia implements both, if you wanna test your implementation. Best, Goffi
