Comment (by vegansalad):

 Let's bring the Axolotl ratchet encryption protocal that is used in Signal
 to Tor Messenger! https://github.com/trevp/axolotl/wiki

 The desktop Gajim XMPP client already has an experimental OMEMO plugin
 here: https://github.com/kalkin/gajim-omemo

 I don't know how best to represent this on TRAC, but this bug has also
 been filed upstream at InstantBird. You can find the issue here:
 https://bugzilla.mozilla.org/show_bug.cgi?id=1237416 If anyone has an
 account at bugzilla, it might be worth it to somehow keep both tickets
 updated as the other one gets updated.

 From what I understand, Tor Messenger would need to impliment these two
 ProtoXEPs to get OMEMO to work. Should I make a child ticket to add
 support for them? Are there other XEPs that need to be added? Do other
 people have other subtasks that they know would need to get done to make
 this transition?

 XEP-xxxx: OMEMO Encrypted Jingle File Transfer
 Abstract:       This specification defines a Jingle application for
 transfering encrypted files from one entity to another. The protocol is
 based on the regular Jingle File Transfer specification and diverges from
 that only in the description of the file.

 XEP-xxxx: OMEMO Encryption
 Abstract:       This specification defines a protocol for end-to-end
 encryption in one-on-one chats that may have multiple clients per account.
