Isn’t OTR protocol Indeoendent? I remember using it even through Facebook via Pidgin. OMEMO seems tied to XMPP.

- upofadown 6y agoThe OMEMO killer feature is that it can deal with clients that are offline. Unfortunately it needs access to cryptographic state stored on a server to do that. So it can't be used in a generic way like OTR. In the case of OMEMO it uses a generic XMPP persistent data feature to store that state. So OMEMO causes a requirement for a particular feature enabled on the server ... which is slightly tacky in the XMPP world.
- MattJ100 6y agoFor the record this feature is a pretty core part of many things in XMPP, and is enabled on 98% of this sample of 670 servers: https://compliance.conversations.im/test/xep0163/ https://compliance.conversations.im/test/xep0163/ The ones without it are mostly special cases (e.g. gmail.com is on the list, of course).
