Yes. I think that I will utilize XEP-0473: OpenPGP for XMPP Pubsub.
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.
Thank you very much for the advise! I will surely do so.
Best,
Goffi
