I wanted to add E2E encryption of all of my messages (Chats and MUC) and looking at OTR seems dead though there are efforts to revive it with OTR4. Also OTR3 does not support MUC. So I was looking for a other alternatives and I’m left with OMEMO and OpenPGP. I would have preferred OMEMO if its license was something as permissive as Smack. So I’m left with OX. However I cannot see it included in Smack 4.3.4 nor it is found on JavaDocs. However it is on Git and seems to be well maintained.
So which version of Smack included OX? Here is the relevant part of my build.gradle
implementation "org.igniterealtime.smack:smack-android-extensions:4.3.0"
implementation "org.igniterealtime.smack:smack-experimental:4.3.4"
implementation "org.igniterealtime.smack:smack-tcp:4.3.4"
