            Bug ID: 93090
           Summary: Telepathy should support OMEMO encryption
           Product: Telepathy
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: critical
          Priority: medium
         Component: libtelepathy
          Assignee: telepathy-bugs at lists.freedesktop.org
          Reporter: malte_e1 at mailbox.tu-berlin.de
        QA Contact: telepathy-bugs at lists.freedesktop.org

There is an ongoing debate about OTR encryption in telepathy. The developers
have argued that OTR was flawed (which is true), the proponents of OTR have
argued that it's the best we have, the de facto standard and pretty much the
best we can get from a security standpoint, which is also true, IMHO.

To fix this problem temporarily, developers of telepathy front ends have
implemented OTR in their products, a solution that works, but kind of defeats
the point of having a unified messaging framework across platforms.

But there seems hope: the android XMPP client conversations now has OMEMO,
derived from Signal's axolotl and supposed to have all of OTR's disadvantages
while solving all its problems.

I am no cryptography expert, but I do want all my chats encrypted. OMEMO seems
to do that without the hassle that OTR has (allowing multiple clients and
delivery of messages stored on the server without the client receiving
gibberish).

So I would very much like to see OMEMO implemented in telepathy to help it
become the new standard and make privacy a little less cumbersome. To me, just
like to many others, privacy isn't optional. If you refused to implement
encryption because OTR was flawed in your opinion, then you have no reason not
to implement it now!
