#OX (XEP-0373, XEP-0374: #OpenPGP for #XMPP, without security problems of historical XEP-0027) implementation has been merged to #Libervia, thanks to Syndace again, and #NLnet for their funding.
OX doesn't have PFS (https://en.wikipedia.org/wiki/Forward_secrecy) but that means that new devices can access archives, which may be desirable. Also, it can encrypt arbitrary elements.
