However, I am thinking of encrypting the data, yet I
do not how to
implement such system which will be possible to decrypt only by the
owner of the data, and I also do not know how to handle a situation in
which an encryption key was lost.
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,
