Answer 1

You don't have to "generate fingerprint" for MUC usage. OMEMO uses the same identity keys for MUC as are used in one-to-one chats. Basically a message to a group chat is simply encrypted for each and every recipient.

Sorry code sample is not possible because of secrecy. But i can give some hints.

You are aware of the fact that smack-omemo-signal is licensed under GPLv3, right? ;)
