Bug Description
Binary package hint: empathy
Hello,
I just tried empathy (the Intrepid version) and it looked very solid and stable. There were a few minor things that could be improved (e.g. automatically resizing the contact list), but that is not the topic here.
The reason why I won't switch to empathy from pidgin is the missing OTR support (http://
There were others with the same idea (links at the bottom).
Would be so great if it could support that important encryption standard.
Thanks for helping out!

The draft Messages UI should theoretically allow anything that has a MIME type.
The underlying protocol support is another story, however.

C-library[1] and python binding[2] are availible, too. So "only" the telepathy glue is needed. After that minor extensions to the different user interfaces really make it functional.

Downgrading priority; there are more pressing spec issues, and I think that supporting encryption on protocols like XMPP where it can be done cleanly (rather than as misc. sent in the regular plain text stream) is a higher priority.

I consider Telepathy to be completely broken for my purposes unless it interoperates properly with OTR on other clients. If you want to do a better version of OTR with deniability in XMPP, go right ahead. Just make sure that the old way still works.
Adium having built in OTR support has been a fantastic boon.
I will discourage everybody I know from using Empathy and uninstall it on systems I administrate until this is fixed. This should have been thought of in the very beginning and been a feature in the program since its inception. Bad security is unforgivable.
You treating this as a low priority bug tells me a whole lot about what kinds of things the Empathy development team thinks is important, and good security is apparently not an important consideration.

As the Empathy developers are more knowledgeable with what users want, or at
least have better tools to gather the information, I guess they have different
list of priorities of tasks to work on.
> Bad security is unforgivable.
This is the kind of program where security is good-to-have feature. The OTR can
be added later, once the basis is stable.

Nobody is against good security. It is just a matter of percentage of users
that are needed to be catered to first. As the developer's resources are
scarce, they need to judge carefully where to direct theirs efforts.
At this point empathy is barely suitable for everyday work (which is important
for about 90% of users), whereas security is important for about 5% of users.

I have to disagree. Although I fully understand the fact that no developer is willing to take up that task, security should be a priority for all users. For me security is part of the basis. A chat client without encryption I do not consider to be functional. I dont chat with people sho do not use encryption. I think Telepathy is more than stable, as it is already part of GNOME and Empathy is going to be the default chat client for Ubuntu 9.10. I would have It is also true, that OTR is broken by design. but it works and I dont know of any client which provides a sane implementation of a chat encryption bedides the ones using OTR.
So again its only up to current and upcoming developers to decide if they are going to implement OTR, but I consider it much more important than providing a lot of chat protocols.

I have no stance for and against OTR encryption and I don't know what OTR encryption is about behind the scenes. I will therefore judge only by your words.
You seem strangely interested in security... provided by (by your own words) a broken security layer? Do you really think that providing broken security, and lulling people into false sense of security is better than providing no "security" at all?
And to others. I am not a Telepathy developer... but seriously guys, flaming developers while not being ready to get yourselves on the line? If you find it useful and especially if you find it critical, do it yourself. Otherwise, feel free to keep using Pidgin until you get this critical feature, which Thilo considers broken by design.
I think there's room for other improvements before encryption, because I, and many other home users, find it unnecessary. Encryption is not important for majority of people on this world.
Take your tinfoil hats off, people, nobody's going to eat your brains. And if you really need it for your company, well, either you or your company can invest resources into Telepathy. I personally don't find OTR important, and I'm sure most users don't, either. And I don't consider myself completely paranoia-free.
If other clients provide you security, use those. Or use email+GPG for even more security. Filing a request is fine. Posting a comment supporting the request is fine. Attacking people like some of you did is not fine.

OTR's brokenness is due to the fact that it is a hacky kludge on top of existing IM protocols, not because it has any security flaws. It's inelegant and ugly, but it works.
I'm all for an elegant solution. But I don't think it should take a backseat to interoperability. I know that the various IM protocols are also mostly a bunch of ugly kludges as well. But that doesn't stop them from being implemented.

I am worried because Empathy appears to be getting a huge userbase and being used as the default IM client for a number of distributions without having a feature I think is incredibly important and should've been built in at the start, almost especially because most users don't really care about it.
Most people will not care about encryption. Most people also do not care about ACID database semantics. But anybody who made a database lacking the latter feature (i.e. Microsoft Access) would be roundly and justly flamed. Especially if they managed to somehow get that database into general use.
There are a whole host of features that users do not care about but are critical pieces of infrastructure. One of the things that most pleases me about Adium is that the developers understood and so many of my friends who have no clue or desire for encryption end up using it anyway because they use Adium.

Email encryption is nearly a lost cause. But with Adium and a couple of other popular IM clients supporting OTR, widespread IM encryption was beginning to happen. I don't think activists in Iran should have to worry about which IM client their friends are using in order to avoid being snooped on. I don't think their choice of IM client should be able to be used to single them out for special treatment by their government. All new IM clients should just do the right thing out of the box.
Widespread support for good encryption is not something I care about because I am especially paranoid about my own IM conversations. It's because I care about the pernicious effects of all IM conversations being potentially public knowledge.

Eric, flaming is not going to give you anything.
If you need OTR so much, either propose a patch, or don't use Empathy.
OTR is not going to happen if nobody gives a patch. End of discussion.

Even if you, or any Empathy developers, don't plan to implement OTR, it's still an important feature and the priority should be set to high.
Or you don't agree it's an important feature? If that's the case I can provide evidence.

"priority" is the priority that we, the current Telepathy developers, give to implementing OTR. If it's a high priority for *you*, you're welcome to implement it, or hire someone to implement it; but it's not a high priority for *us*, and so it stays priority=low in Bugzilla.

OTR also works over non-XMPP networks (I use primarily over AIM). That's something that this XMPP standard can never achieve.
I'm not taking sides - just stating some (hopefully) useful facts.

By far the overwhelming majority of IM clients in use are those provided by the protocol vendors, and I can assure you, they don't ship with OTR. Empathy's userbase is growing, but it's stil early days and it's likely not going to dwarf the others anytime soon.

No, they should not be flamed, and this is the reason your posts are so inappropriate: you think that because feature X is missing, developers should be flamed. Developers in a number of projects work on a voluntary basis, and in my opinion deserve some semblance of respect for their contributions, not being hassled by the likes of you.

OTR is not a generally accepted critical piece of infrastructure.

Perhaps a nice utopian vision of the future, but not the basis for a rational discussion. This is an unqualified "oh-won'
It sounds like you have strong convictions. Strong enough though only to sound off about it here and not really do anything about it. If these objectives are so important to you, why aren't you writing your own OTR extension now?

Reality: People's choices in the technology adoption affect their security. You can't control the proliferation of technology, and you can't control people's choices. You lose on both counts.

You only care enough about it to flame the volunteer developers who are working on the IM technology -- not enough to actually do anything about it yourself and contribute to make it better. Oh right, you're also boycotting Empathy/Telepathy and telling all your friends not to use it.

Hello all,
since I am the creator of this "bug", I feel obliged to calm the waves a bit and add a plea for seriousness in this discussion.
What some developers might call "broken by design" is probably the backside of OTR being a technology that just works with each and every IM protocol out there, even the worst ones like MSN and Yahoo. I presume, providing such a bandwidth of features just wont go without some kludgy solutions.
In my daily life (and in the life of many others I would bet) practical solutions are what counts and what is needed. OTR is a practical solution.
As a contract worker for several German companies I can tell you that in many European IT departments OTR has become the de facto standard for on-the-fly exchange of information bits like the casual end user password and similar stuff of more-than-zero triviality.
To the best of my knowledge, all current versions of OTR provide no "false security" when properly used and the fact that they might not be working very elegant "under the hood" is actually the bit that is of "minor importance" to me.
For me, the important point is that I totally depend on a cross-protocol encryption solution for IM that "just works" in my daily life and so do many other people. OTR is already here and has been for several years now. And despite the fact that there might be more or less obvious and more or less major disadvantages to OTR from the developers POV, *not* *one* single viable alternative has come to my attention in the last years that is not forcing users to use a specific IM protocol or even a specific OS platform.
Conclusion: Unless proven otherwise I'd like to state as a FACT that in the field of IM privacy, OTR has become the de-facto standard. At least in Europe it is very widely deployed and often expected to be available. And there are just no alternatives available at all which work cross-protcol and cross-platform.
From my POV this means there is also (currently) no alternative available to implementing OTR for every IM UA that wants to be taken seriously.
Thank you for reading.

I will not use empathy without OTR support either. The statement of the developers is absurd - they think, that their users dont need it and the only other option is to wait until there is native support in some protocol, which most users dont use or even know about. So thank you for telling me, that I dont need OTR and should convince all my chat-buddies to switch to jingle, but I prefer I to choose what to do with my computer, so until there is OTR support for empathy I will use Pidgin.

The underlying idea of empathy/telepathy may be good. But really important things are ignored. To move the responsibility to ONE protocol (jabber ) which may implement encryption in the future is really unsatisfying.

Not to mention that the proposed idea for implementing encryption over Jabber doesn't give the same level of privacy guarantees as OTR, nor is it actually as nice a standard in a lot of other ways.
The average user will never generate an X.509 certificate for themselves. Anything based on that kind of technology is broken from the start. It's like making an email application that requires the user be in X.500 directory before it delivers mail.

I'd say that the default chat client should have OTR support, but no
problem with having other choices that don't, Empathy has voice and
video, which does make it a nice option.

I concur -- OTR support is needed, for sure. For anyone truly dedicated to Empathy, you could run the AIM proxy or write your own for any chat protocol (could be done easily in Java, libraries for most major chat services already exist.)

Yay! Though, I looked over XTLS and I think it's a horrible idea. The worst part of TLS is x.509 certificates for a whole host of different reasons, and one reason OTR works so well is it adopts the ssh model of verification over the stupid x.509 model which doesn't really work for anything but domain names (and even there is way overly centralized).
But OTR support would be good. One issue though is that there is an ad-hoc method for doing OTR over Jabber that several other clients support. It's almost necessary that they support that method as well, and it's not clear that they intend to.

Empathy might think that they are cute and functional with video and voice chat, but I will never use it if I can not send my admins passwords and system information without worrying about a security breach.
Please include a plug in system in order to accommodate OTR. Secure chats are just as important as HTTPS

Not having OTR support is inexcusable. It's like a browser that doesn't have HTTPS. empathy will stay broken until such time when this bug is fixed.
This is Linux/Gnome, not some bullsh.t commercial application, it is supposed to have encryption, it is supposed to be interoperable. OTR is currently the only standard that works for IM protocols.
Including this obviously broken app in the new ubuntu release is a very bad move, a'la M$.

Okay we get it. OTR is important to everyone and everyone thinks it's bad
that it's the default IM client in Ubuntu. The fact remains that these
comments are of no use in a bug report (neither is this one for that
matter).
The relevant developers are working on this bug and also get the point.
What's done is done, and the consequential issues are being addressed as
best as possible. Please refrain from polluting the bug report with
complaints and declarations that you will use alternate clients. These types
of comments are better suited in a forum or maybe a blog.

Does empathy support any other form of encryption? I understand this could be challenging when you need to support audio and video, but guys, challenging doesnt mean you have to run away from it.
OTR or some sort of encryption at the client side is a must. switching to pidgin temporarily. :)

As I recall, Empathy feels the world should be fixed. This would be
nice, but it is a long ways off. So, yes, they have switched the
default IM to empathy, which has no real plans to support encryption
in the foreseeable future (xmmp crypto someday?), but Pidgin/OTR will
remain installable. Of course, soon enough, video/audio will be
working in Pidgin.

Just to clarify;
1. the fedora guys have marked it as wont-fix
since which we read this comment in the fedora bug tracker:
Jonathan Blandford 2009-11-16 08:23:37 EST
[ Note that upstream has since changed their mind on that, and claims to be
considering how to include OTR. In the short run though, its gotta be pidgin.
]
2. the ubuntu guys have marked it merely as triaged, not wont-fix
Also I note the main advantage of OTR is that it supports end-to-end encryption even when the transport does not support encryption.
In the mean time I'm the cause of Ubuntu being dissed by my associates because Pidgin doesn't support video or audio chat, and I'm certainly not going to use Empathy in it's current state.

So, this is triaged and wishlisted, is anyone interested in implementing it? I am.
I agree with the developers' general concerns regarding OTR, it doesn't work well, but it works with users of common IM clients on all operating systems. I have a lot of experience with its' funkiness
The most important use of OTR for serious IT? Giving users secure passwords, or asking them for a new password for a service which must be reset by an admin in the shell.
Second most important? Talking about competetive business ideas that might compete with companies who own and operate huge IM networks. It shouldn't be possible to operate a dedicated, physically secure server to have a secure conversation.
The deniability aspect is not the most important thing to me, I'm not sure a mainstream product needs to AIM FOR giving users deniability, as this implies intentional protection of wrongdoing, but it is essential to be able to secure at least portions of a conversation, selectively, and in fact OTR's PGP-based system is effective at removing deniability when that is intended, so not just encryption, but signature identity.
Anyway, I'm interested in helping to implement this feature if noone currently is. Pidgin is, in fact, a flaky pile of crud that evolved from gaim which evolved from who knows what, paper cups and string. The biggest problem I have with Pidgin is that it sometimes just stops accepting pastes, so that's been enough for me to decide that OTR is no longer my favorite feature, though still an important one.
That Empathy was flung onto Ubuntu users with reduced functionality and arbitrary opposition to reproducing commonly used functionality, however, is inescapably ironic to me. ;)

Things like this: http://
Concern me greatly. While it would be wonderful to have the end-to-end communications secured natively in the protocol, the sad truth is that we're never going to get an update to the legacy protocols to support it.
And no, the answer isn't "Just move to another instant message platform"
One of the advantages of tools like Empathy is the ability to support a multi-service situation. It allows me to run a single app, and connect to any service I need.
The arguments that, "Pidgin supports it, you should too." don't really hold much water. I go back to the requirements that drove me to OTR in the first place.
Encryption: No one else can read your instant messages.
Authentication: You are assured the correspondent is who you think it is.
Deniability: The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured the messages he sees are authentic and unmodified.
Perfect forward secrecy: If you lose control of your private keys, no previous conversation is compromised.
So, to me it's as simple as that. Please find a way to get the above services into Empathy. I personally would suggest the use of OTR as there are already libraries developed you can use to use.

Nate - do you want to help with the implementation?
I've volunteered to do this work, but it is taking some time to acclimate myself to the codebase. The Empathy core developers don't seem particularly interested in this feature, so I think those of us stomping our feet oughta pitch in.
The architecture is really pretty simple, the meat seems to be in a Handler component which is designed to be able to be supplanted, afaict. I just haven't decided how to do this with the least intrusion into already-working code.

"Will Empathy have OTR ("Off The Record") support?
We think that the correct approach to secure end-to-end communications is to support it natively in the protocol. There is ongoing work on standardising secure end-to-end messaging in Jingle (using XTLS and Jingle) and we plan to support this in the future (current API sketch).
We don't think that layering encrypted messaging on top of protocols that don't support it is very useful, since such extensions won't, by definition, work in native protocol clients, and any clients that do go out of their way to support encrypted messaging might as well do so using a native protocol.
Nevertheless there is a bug report talking about OTR support, and a comment dated October 2009 is talking about API sketches for encrypted channels and OTR. <https:/

Is there any hope to get it in the final release of 11.04? That would be awesome!! The first Ubuntu release with OTR in empathy I'll be switching my business and family over to Ubuntu.

Actually, it would be impossible to have made the cut for 11.04 just
because the day I started the project I would have only had two weeks
to get something pushed through and then approved for the code freeze
date. However I am shooting for 11.10 and I now have two more people
that will be helping me with it. The major push for the project will
begin in mid-May and hopefully our code will be accepted before 11.10.
But initially their may only be support for Google and MSN, possibly
Yahoo. The rest will follow those and Google and MSN should be
completed about the same time. The reason for MSN being supported so
early is that the connection manager for it was programmed in Python,
which is the language I have more experince in.

Mark M (ubuntu-prototribe) wrote : | #109 |
I've been tracking this bug over the years and am very happy to hear momentum is gaining. I'd humbly like to put forward a use case that may or may not affect how the implementation is performed.
I regularly use OTR via Pigdin to securely communicate from a jabber account through a private jabber server then through a IM gateway to many AIM, MSN and Yahoo accounts (required by work). This is one of the areas where OTR shines as it is protocol independent. One of the reasons that OTR managed to gain popularity is its entire protocol is wrapped in the text that is transferred between users (read as, "it just works"). It manages to avoid all sorts of complexity and issues by staying entirely out of the existing IM protocols including any sort of server side changes or support.
Adding encryption into the jabber protocol (XTLS/Jingle) doesn't help unless there are encryption and federation standards that are supported across all IM protocols and i'd imagine that would be harder to get implemented than this bug. =)

@ZAP: Thanks for volunteering. I will let you know when I have something concrete. I am still tinkering and there have been some changes to implement OTR only rather than accommodating XTLS too. One thing I have to be careful of is that OTR is considering dropping support for Python-OTR, which could be a problem for me. But for the Google IM and Jabber this will not be a problem. João Paulo Rechi Vita is helping to get the spec right and will be writing the code for the Gabble CM.

As for python-OTR, [1] has released the first beta of the pure python implementation protocol, it doesn't seem the authors are dropping the support for a python bridge, but it's true, they mention the "deprecated" C-style bindings that were available before.

Hi Anand,
I have pulled back work on a pythonic fix for the Telepathy OTR situation. But before I did that João Paulo Rechi Vita started advancing my work and has since completed all of the spec work for OTR. He is now building the Telepathy Gabble OTR code and will then finish the Empathy hooks that will be needed for OTR support. Gabble is the Connection manager for Jabber and Google Chat. He hopes to have all of his work wrapped up by the end of this month. His website is here: http://
He is a more seasoned developer than I and he was able to communicate with the Telepathy Developers better and faster than I was able to. Sorry for bugging out, but the pace of his work far out paced my work. But I am still watching developments for this project and will ensure it gets completed, but I am pretty sure João has got it.
Once his work becomes a solid spec I may still go back and finish the Python version which will add support for MSN. I also think that porting his code from Gabble to Haze should not be too difficult, which should round out the the IM OTR support.

I am tired of pidgin and very interested in Empathy. But i depend on OTR, so i cannot switch.
I know 5 others in my local geekosphere who have the same.
OTR is unaware of the layer below. That makes it clumsy or unelegant to implement for an individual protocol like XMPP. But at the same thime this is a strength: a multi-protocol IM client with OTR has end-to-end security with the same key pair on all protocols used. And that is elegant again :-) Calling that "broken by design" is a narrow view and missing the point of OTR.

It has been two years and there hasn't been an update on this. Telepathy is in a well working state now but there is no sign of OTR encryption. I love the concept of telepathy but it not having support for OTR is really a showstopper for me and
ALL linux users I know personally. OTR can be considered a major feature for people concerned with security, which most linux/BSD/etc. users are. It's sad this bug is just left aside with low priority. I can't program well, so I can't fix this but I really hope somebody will soon. This would make telepathy more awesome than all other messengers. Until then I will have to stick with something else.

Nothing to highlight here. Many bug reports here have not ever seen a comment for more than two years.
"Open Source" is not "the developers must do my bidding." Everyone wants to help, but no one else has any obligation to fix the bugs you want fixed. Therefore, nobody should act as if you expect someone to fix a bug by a particular date or release. Contributing patches normally helps, "I want this too!" comments not.

OK, soon gsoc will start again. Maybe it can used to find someone who will implement OTR in telepathy. Does anybody has good connection to telepathy/gnome/fdo developers to ask if they would provide a mentor for such a project?
What really annoys me about the otr integration in telepathy is the lack of information you get. People (e.g. jprvita, McVittie) come and go. Someone never hear something again about the project and the status. There are some questions in my head. Something like, is the approach of jpvita usefull for furher devlopment. If it's useful, what needs to be done to finish it?
I think it would be useful to have a wiki page with such kind of informations. I can't believe that nobody is willing to code on this, so the question seems to be what keeps developers away from coding on this or vice versa what incentives must be given that someone is willing to work on otr implementation.
P.S. Don't get me wrong I don't want to blame anybody with this post. It presents just a couple of questions which have risen in my head.

@sam-liddicott Empathy does not need to support OTR, because *there are no* alternatives that do. Empathy needs to support OTR, because *there are* alternatives that do. It is state of the art to support OTR and Empathy not including it is backward.
Empathy is the instant messenger included the GNOME desktop which ships as a default for many modern distributions, so Empathy is itself a default. An user could educate oneself about this default, notice this backwardness and replace Empathy with a less backward instant messenger. Educating oneself about the security of the installed instant messenger requires but examination that not all users may be able to perform, because of the complexity of the topic. So especially the less computer literate users, who would benefit the most from it will not get covered by OTR.
So this boils down to a question of defaults: Should the default be to ship an instant messenger with OTR-support with GNOME desktop? I think recent revelations have shown that "security by default" should have been targeted wherever possible for a long time now.

Also, don't forget about the ZRTP option, as discussed in the Bug #29904.

Maybe someone is willing to spend some time on this. I tried at a point to gather some support, but well the core developers of empathy believe OTR is a bad idea, and well jprvita is not willing to continue with the project, wolfrage seems to have disappeared and so on. Anyway, trolling won't help, just a reminder that the bounty is now higher.

I am sorry if you feel that I have disappeared. I did not intend it that way. I did what I could to help. The developers of empathy stated that they could not implement OTR unless they had a spec first. They also forced the issue that my spec had to include XTLS. I am only a novice programer and certianly not a spec writer, I also volunteered for far more then I could handle hoping that OTR would be a welcome addition to Telepathy. Unfortunately even after the Spec was ready for review, it never recieved a review. I also was working in Python as that is what I program in, and Telepathy removed support for Python around this same time. JPRvita told me that he would take my spec and complete it for XTLS and that he could program in C. For a long time it looked like this would work. JPRvita had a solid spec, but as happend with me the spec was never reviewed, I am not sure what happened to him and his GSoC XTLS/OTR Spec for Telepathy.

Honestly my take is that this is a developer issue, they don't want OTR and no one can force it upon them.
So I got over it and I use Pidgin.
FYI for "cbris" or "ScotlandHacks" you should use jprvita's Spec it was much further along than mine, it is here: https:/

Please bump the priority for this. If you can't add OTR support then please give instructions how to add a plugin. I've been waiting patiently for several years for this support. I was thrilled to see an IM client get audio and video support on Linux. Now it's time to get encryption. We have the evil US empire spying on human rights activists, protesters, etc and by not supporting encryption we're enabling that spying.

From comments when this first arose, the empathy developers were not
interested in something that was interoperable with OTR, but might,
someday, be interested in their own unique snowflake of an encryption
system.
I'm not a coder, but OTR is out there, works, and plays well with others.
They really ought to make it work in empathy, one way or another. Perhaps
there is a new bug that people might pay attention to, given the emphasis
on crypto these days?

After all that NSA, PRISM, etc, scandal, I don't want to imagine the silly face Telepathy's developers who stated so arrogantly that security wasn't very important must have every morning. They thought that critic users who were demanding security were little less than intellectually retarded people, who couldn't distinguish what is really important, whereas they, the developers, in "Their infinite wisdom", had the Truth, knowing what was prioritary, not us, stupid users who can't even code.
After all these of costant slapping in their faces from the news, the papers, the public; in short: the reality, one would think they must have become a little humbler (Christ, they even rejected to work on encryption despite people was ready to collect money pay them to do it!), but it seems that things haven't evolved too much, right? (KDE's Telepathy implementation has even been removed from Prism Break website because its [lack of] security is just unacceptable: https:/
Well, we, the critic users, aren't developers in this project, or at all. We can't tell them to do what we think is prioritary when the other 90% of users think is not (y'all know: a trillion flies can't be wrong. Let's eat sh*t), nor can we write an encryption plugin, so I think all critic users should stop trying to make TP devs reason, it's a lost cause.
I suspect that Collabora, the company after Telepathy, might have been intentionally delaying as much as possible the "securization" of Telepathy. We known now that the obscure hand of the NSA has been involved in the development of cryptography standards and even in TOR. As an iceberg's peak, surely we don't even imagine the 90% unter the water. Suspiction is not knowledge, of course, but all that immovable interest in not writting a damn plugin for OTR o implementing any other secure encryption method year after year, even when people was ready to pay... Well, it just smells rather fishy.
So, dear folks who do know that fascistoid governments and companies arent interested in "bad guys" only but want to have controlled all of their people "just in case", simply use Pidgin; it's ugly as a witch, yes, but it works; or if you want to polute your system with Java, you have Jisti, which is more feature rich, but I don't think all this discussion, all this bitching and all that "We are the devs, if you wan't something do it yourself!" has any sense, and even less if there are interests who don't want our conversations to be private.

I think most people take it for granted that telepathy devs are on the dark
side - even the name of the project gives it away!
Telepathy is for other people to read your thoughts.
But it's bad manners to bring it up on the bug report list.

I'm fed up of people complaining about developers. It's *free software*, and if you get anything more than you paid for then you should be grateful (I certainly am).
This is doubly so considering all the criticism that has gone the way of the OpenSSL people in the wake of Heartbleed. When someone gives their best effort to produce software as a gift to the community, often working in spare evenings with lots of other distractions which prevent them giving their full focus to the task, they get next to no praise when it works and a whole heap of criticism when they make a tiny mistake. People even accuse them of deliberately inserting the mistake as a government spy.
I'm currently writing up my PhD thesis. When I finish, I will have some free time while waiting for my viva voce, and would be willing to spend some of that time trying to fix this, as it is something I would find useful myself and potentially also a helpful addition to my CV. However there are probably plenty of people out there who would do a better job than I, especially since I have mainly used Fortran and Python for the last 4 years so my C/C++ is rather rusty.

Well, my issue isn't how the devs choose to spend their time, but the
extremely hostile and dismissive attitude they took towards security and
privacy when they have addressed this bug/feature request/feature.
I haven't paid them, they are not obligated to me, I am disturbed that
Ubuntu would switch to an unsecurable chat software as their default. I'm
disturbed that people would have such a hostile attitude to security and
privacy. I'm not bothered that they don't want to spend their time doing
it.

I'm feed up of people complaining about people complaining about wilful bad
security.
This is doubly so considering all the criticism that has gone the way of
the OpenSSL people in the wake of Heartbleed.
A little more discussion there might have helped, but here it obviously
hasn't!
When someone gives their time and experience to improve software designs
from fatal flaws, often in the evenings with other distractions, they get
next to no gratitude and a whole heap of criticism as if their drawing
attention to the flaw is worse than the flaw itself.
Free software doesn't stop people talking about the naked emperor.
If they are not government spies and but just play at spies in their
evenings (with other distractions) then that is fine, but if they then make
a public gift of it can they really expect people to not talk about it?
They don't buy our silence with their wooden horse!
We don't use it and we warn others. We actually care about their users!

I'm not complaining about people who spend time auditing security software and finding these bugs making their discoveries known - even if they are less than polite while doing so. (I myself am taking maximum advantage of the opportunity to poke fun at ridiculous or borderline fraudulent statements I've spotted during my literature review - it's one of the few redeeming features of writing a PhD thesis.) They are just as crucial as and even less appreciated than the developers. Certainly if I get round to writing this code it will need their attention.
What I don't like are people who do nothing except repeat something we already know ("This software doesn't do X. People want it to do X.") but louder and more rudely.

I think people are trying provoke a post-Snowden comment from the devs or
Ubuntu.
This uncomfortable discussion has an important social role in establishing
or restoring or writing off credibility.
Pre-Snowden the official position seemed incredible, but potentially
honestly held.
It may even have been part of the Ubuntus baffling but consistent long term
strategy of replacing working software with half finished software.
But post-Snowden we see an opportunity to discover if they are accidental
helps or wilful supporters of the evil empire.
Thus are reputations forged.

Complaints show fear, anger & ungratefulness while calm feature requests
show peace, gratefulness & understanding of a problem.
Community giving of FOSS shows kindness & compassion, while taking &
complaining shows an unsatisfied desire for control.
True control lies in harmonising with the community, and paradoxically
involves letting go of your need for control while also giving the part
which is under your control.
Heartbleed shows inherent insecurity of a house divided against itself....
yet it also shows the speed of the Whole to heal itself.
Privacy is an illusion... security built on deterministic Laws has little
room for true randomness without hiding within Complexity. The appearance
of randomness is Chaos, yet within the chaos lies a higher Order.
No matter which side you think you are on... you're actually on both, and
they are not truly opposed when undivided.

Here it is! It is limited to XMPP, and empathy has only rudimentary UI. To start an OTR session, in empathy chat window, type "/otr start". Type "/help otr" to see other supported otr actions. There is no graphical UI atm.
Notably, to authenticate the other end, you need to verify its fingerprint by other means, like IRL or phone, etc, then type "/otr trust". It remembers fingerprints you trust of course, so you won't have to repeat that for each conversation.
I tested this between empathy and pidgin-otr only.

Could we also get a config option that turns this whole feature on/off?

The conversation won't be encrypted until you type "/otr start" or if the other side request a private conversation. So you should be fine AFAIK.

Just because the conversation is encrypted end to end doesnt mean you cant log locally. Dont know how empathy does this, but in pidgin it can be set up easily. There is even an option to omiss the conversations that are encrypted.
I dont really like that distinction, because it implies all encrypted communication is sensitive. Rather its best to moreso always encrypt so that you dont draw attention to something by said connection.

Actually I was wrong, when both sides are OTR-aware, it initialize itself without an explicit user request. I changed the policy from DEFAULT to MANUAL and now it won't start encrypting until explicitly asked by one side.

No it returns the cached variant. There is a _dup_ method as well in the generated API.

Properties are fetched and cached when creating the proxy, there is a _new_for_bus_sync() call. I added an extra patch to make it async now.

The fingerprint I send over dbus is in 2 forms: the 's' is formatted to display to the user and the 'ay' is the raw data of the fingerprint which cannot be displayed since it's not utf8.
> What happens if the user doesn't trust the fingerprint. The communication is

By default it's not encrypted at all. When one side does "/otr start" it will be encrypted but a MITM could have set its own public key instead. So both sides must verify the fingerprint by other way (like calling, or asking IRL, etc) then if they checked the the fingerprint wasn't changed by a MITM they can do "/otr trust" and it will remember that <email address hidden> has that fingerprint and if future conversations uses that fingerprint then it's still trusted. That's why we have different TrustLevel:

Yep, the user knows it succeeded when he sees the trust level change message. If it fails then trust level won't change and user doesn't know what happens. Handling the error here will only mean something failed on the DBus level, we have no way to know on the OTR level if it failed. For example if the other side does not support OTR at all, our initialization message we send won't receive any reply and that's ...

From a (very) quick look on the Gabble branch, it seems that all the channel messages are now sent through OTR (if built with it), even when it has not been activated. Is that really what we want?
Also, shouldn't we use it only for contact channels?

Yes, that's what pidgin-otr does as well. That's because all received messages needs to be parsed by OTR first because it will catch message starting with "?OTR?" because when receiving that it means the other side wants to start an OTR session. In that case the message is considered as internal OTR protocol message and it returns ignore=true so we don't dispaly that to the user.
We could avoid passing sending messages to OTR when session is not started indeed. I didn't do that because OTR will just return a copy of the initial message so it doesn't change anything (just wasting CPU cycles), and I prefer not adding any conditions to make damn sure we never have the case where we send something that didn't got encrypted first.
> Also, shouldn't we use it only for contact channels?
I don't think OTR can be used on MUC, or at least that's out of scope for now.

I assume the meanings go something like this:
TRUST_NOT_PRIVATE: not using OTR at all? (Can we also see this when using OTR but something has gone wrong?)
(o.fd.Channel.
TRUST_UNVERIFIED: the channel is encrypted, but you might be talking to a man-in-the-middle instead of the peer you expected. (o.fd.Channel.
TRUST_PRIVATE: the channel is encrypted, and the user has indicated that the peer's key fingerprint is trusted to belong to that peer.

When we're in the UNVERIFIED state, am I right in thinking that we are cryptographically guaranteed to have the right fingerprint for who we're talking to, but the thing that is unverified is that the fingerprint belongs to the person we wanted to talk to? (i.e. if we're talking to a man-in-the-middle, this would be the fingerprint of the man-in-the-middle's key, right?)
Is it possible for this to change? (Presumably from ('', []) to non-empty, at the same time that the trust changes to UNVERIFIED or PRIVATE?)
After this has become non-empty, can it change further? (I would hope not.)

+ TP_CHANNEL_
Is this a message from the OTR library, something like "*** Verified peer fingerprint: <email address hidden> ***"?
I think using the target handle for this is OK semantically.
However, I suspect remote users can spoof this by sending their own NOTICE. Messages coming from the OTR library should have a distinctive message header that an OTR-literate UI can take as evidence that they were locally-generated.
Ideally, that distinctive message header should be a machine-readable version of the message, so OTR-literate UIs (Empathy) can discard the untranslated version from Gabble and display something translated. We've always had a policy of putting UI strings and their translations in the UIs, not the CMs.

The magic number 20 makes me nervous. Isn't there a constant for "length of a raw OTR fingerprint in bytes" in libotr?

I think we do need a connection parameter to control this. I think the possible sensible settings are:
- never use OTR, behave exactly as though it was not implemented
- start an OTR conversation if the local user or remote peer explicitly requests it
- try to start OTR conversations automatically

Corner cases:
What happens when we try to send a message and the channel is already TRUST_FINISHED? I think we should refuse, for the rest of the lifetime of that channel (until Close()), to avoid the security flaw where we send messages to a channel that just closed.
What happens when we close a channel locally? I think the answer should be "we terminate the OTR session, and start from an unsecured state next time" - even if the channel is in fact going to respawn due to unacknowledged messages. This means the channel needs to reset its Encrypted flag, Verified flag and all OTR state when it respawns. We will still be able to tell the rescued messages were encrypted/verified because the header that I suggested adding will say so.
What happens if I'm talking to <email address hidden>/Laptop using OTR, and I receive a message from <email address hidden>/Phone without OTR? I hope the answer is "libotr deals with it and reports OTRL_MSGEVENT_

The more I think about this, the more I think Gabble should not contain translated strings. It's OK for it to contain strings in the C locale (international English), but all translation should be taking place somewhere that already needs to be translated - the UIs.
As a purely practical thing, Gabble does not have any of the translation machinery, so those strings aren't going to be translated anyway.
Is the OtrlMessageEvent enum sufficiently stable that we can use it in the D-Bus API directly? That would probably be the easiest way. The only other information we need to put in the message header is:
- for OTRL_MSGEVENT_
(perhaps { "otr-error": that string })
- for various codes: the username or account name, which the UI already
knows anyway
- for OTRL_MSGEVENT_
(perhaps { "otr-unencrypte
- for OTRL_MSGEVENT_
(perhaps { "otr-error": that string })

What does that last sentence mean in Telepathy terms? If it means "you should close this channel" (i.e. close the Empathy window), perhaps "Close this conversation and try again"? (Or perhaps we should even auto-close the channel, but we're trying to get away from self-closing channels.)

Thought bubble: "no, I'm pretty sure I didn't" :-) If this happens, it's presumably either Gabble's fault, or one of the user's other resources, not anything the user themselves typed.
"Internal error: transmitted an unreadable..." instead, maybe?

After fixing the obvious things, it would also be good to get someone who understands the OTR protocol and/or libotr to review this (particularly the things I raised in Comment #59 and Comment #62).

I *think* (need to double check) that in that case you'll still be sending encrypted messages but the other side won't be able to decrypt them and will display a message "The encrypted message received from %s is unreadable, as you are not currently communicating privately.".

I think it can only increase unless the local user did something. Like it can go from PRIVATE to UNVERIFIED if user types "/otr untrust". It currently cannot go back to NOT_PRIVATE because I don't support ending the otr session, but could add a "/otr end" for that. pidgin can do that.

It would make sense to get an OTR expert to confirm that how we're handling this is secure.

Ah, that's a good point. Please document that transition (although it can only happen because the user did something odd - but that odd thing might make sense as an "undo" mechanism).
I suppose this means that Securable.Verified can turn off as a result of an "undo" button, too...

Please don't. In Pidgin, maybe that feature is OK, because typically only one UI handles a window (Pidgin's D-Bus API aside). In Telepathy, where more than one UI can be interested in a channel, that feature would be an unlikely security flaw: if I type "the secret password is weasel" and for some reason another process turns off OTR just as I hit Enter, that's Bad™.
If the remote peer can turn off OTR, then that elevates that situation to a remotely exploitable security flaw, but AIUI the design of OTR doesn't allow that to happen.

All hex is UTF-8, because hex is a subset of ASCII, and ASCII is a subset of UTF-8... or do you mean binary?
If the machine-readable fingerprint is like "adc83b19e79349
As for the human-readable version, do I infer correctly that it is not just hex, but instead an OTR-specific encoding that is easier to transcribe or more dense or something?

That's OK, but only if MANUAL specifically means "do not initiate *or accept* OTR sessions without user input".

I don't like private APIs. They have a nasty habit of becoming de facto public APIs as soon as you commit them (and we only recently managed to get rid of Renaming being a private API, despite it not having changed for 5 years).
We have API versioning now, so if it's good enough to merge, it's good enough for the spec.

Are you saying that in this message
<message>
<body>
</message>
the recipient is expected to decrypt 123123123 and treat the result as plain text, but in this message
<message>
<html xmlns='http://
<body xmlns='http://
?
</body>
</html>
the recipient is expected to decrypt 456456456 and treat the result as HTML? Or what?
There must be a rule you can use to determine whether the decrypted content is text/plain or text/html. "Text that may contain HTML" is not a well-formed concept - either the message "<" is a 4 character reply to "remind me how you escape < in HTML?", or it's a single U+003C LESS-THAN SIGN character. It can't be both.
It is entirely possible that the rule is "do whatever Pidgin does", which in practice probably means it's always treated as HTML - that's what my review comments assume.

I don't end the otr session yet (adding a patch now to do that). pending messages are already decrypted so user won't know if they were sent privately or not. Indeed adding the fingerprint in the message parts can be helpful. otoh I would consider this future enhancement, when a new chat window arrives if there is no message telling its private the user should just assume it's not. He can always start a new otr session and ask to repeat to be sure. IMO that's corner case so it's not that bad if user needs to ask repeating.

I actually added Stop method (/otr stop in empathy) because when the other side (pidgin) stop the OTR session we have to let user disconnect as well to continue in plaintext, otherwise he can't send messages anymore. Or do you think user should close the chat window and open it again in that case? Having that stop method is useful for testing as well :)
IMO those methods must always be called on explicit user action, if you have bad apps running on your bus session, you lost already.

Remote end can stop otr and you won't be able to send messages anymore until you stop/start it locally again.

It looks like "82AAB578 4FB98B0B AECD3BA4 6083CFE2 E152AD73" so that's actually simple hex with spacing. The formatting can easily be re-implemented client-side, but it's cheap enough to just provide it over dbus.

I was wrong indeed. When other end stops the session TrustLevel goes to FINISHED (added a patch to make that happen) and you are not able to send messages anymore, you get an error message back. I think it publish the private key indeed.

2) Find a solution if we don't want the other end to be able to initiate an OTR session without approving it first.
3) Fix string spelling. Maybe you can patch them yourself, as I'm not native? :)

Looking into it. The more important direction (don't send plain text where HTML is expected, so that parts of messages that happen to look <a bit like html tags> aren't silently ignored) is easy, it just needs g_markup_
The other direction (don't send HTML where plain text is expected) is more difficult, but libxml should be able to do it; and if we don't, the failure mode is that a user sees HTML markup instead of plain text, which isn't *so* bad.

I think a CM parameter is the only way to do this. It'll work for MC-stored accounts (which includes all Haze accounts and all "unbranded" accounts like generic Jabber/IRC, even if GOA is used), and for UOA-stored accounts.
I agree that GOA's account parameter storage limitations mean it won't work for GOA-stored Google Talk or Facebook accounts, or GOA-stored Windows Live accounts in the unlikely event that Microsoft bring back their XMPP bridge. If you want communications privacy, Google and Facebook are probably not the ideal option anyway... and that GOA issue is not something that Telepathy can fix in any case.

Security issue: it isn't at all clear to me what "trust" means here. In something like GPG or SSL, the trusted assertion is "the key whose fingerprint is ...63c7cc90 is controlled by 'Simon McVittie <email address hidden>'" or "the key whose fingerprint is ... is controlled by the administrators of bugs.freedeskto
Concretely, suppose I talk to <email address hidden> and you present key ID 12345678 [1]. I verify out-of-band that that is really your key ID (perhaps by phoning you or receiving GPG-signed email) and mark it as trusted. Next, I talk to <email address hidden> who presents key ID fedcba98, and again, I mark it as trusted. Now Guillaume hijacks your XMPP account, and when I next try to talk to you, Guillaume presents key ID fedcba98. I have "trusted" that key, so my UI doesn't indicate that anything is wrong - but it isn't your key, it's Guillaume's!
How does OTR typically deal with this situation? Do OTR users memorize key IDs and ignore the JIDs and contact names presented by the UI, or does the Pidgin OTR plugin store pairs (JID, key ID) and warn the user if an unexpected pairing is found, or does "trust" here mean "I trust this person not to impersonate any of my other contacts"?
[1] in real life the key ID would be longer than that, but you get the idea

I'm not particularly happy about this type duplicating the information: whenever there's duplication, there's the possibility that the duplicates don't agree. I can see why you did it, though - the OTR library doesn't seem to have a function to convert a human-readable digest back into binary (although we could easily write one), so you currently need the binary digest in order to set trust.
If possible I'd prefer to stick to one encoding or the other, consistently - either always a string (which I think is what I'd prefer), or always a byte-array. At the moment we only put the string form in message headers, not the byte-array.
I'm tempted to implement a function to turn the string into binary (decode hex, ignore whitespace, report an error unless it has exactly 40 hex digits) and just use strings throughout.

Non-blocker but still desirable. Given what I said in Comment #78, I think we can set Encrypted when OTR is active, but we can't set Verified in any case, because the thing that Securable says we Verified (that the key with which we're encrypting belongs to the contact identified by the Channel's Target_ID) does not seem to be what OTR actually verifies.

On closer inspection of libotr, it seems we are indeed binding a (remote username, local account name, protocol) tuple to a fingerprint; the API just doesn't make that obvious.

peers cannot fake. Because Empathy doesn't support HTML messages yet,
distinctive formatting would be enough.
* string-only handling of fingerprints (emit strings to D-Bus,

Nice to have, but not blockers:

The '/otr start' command was displaying "OTR:$blob" in empathy-chat.
I did manage to start a session using Xavier's branch but noticed the following bug:

- In Pidgin using the OTR menu pick "End private conversation"
- Try sending a message from Empathy. The message doesn't reach Pidgin and this error is displayed: "Your message was not sent because <email address hidden> closed their connection. Either close your private connection, or refresh it."

Fwiw, I think I've seen the same message in pidgin when chatting with an adium user who closed the conversation window or something like that.

It's not a bug, it's a feature. User must acknoledge that he's not in private chat anymore by typing "/otr stop" or "/otr start".

You need to set "enable-otr=true" in your CM parameters, otherwise OTR is disabled in Simon's branch. There is magic mc-tool command for that, did not try yet.

#237 |
(In reply to comment #87)
> Why is the patch protocol-specific?
Telepathy does not have any central point where OTR can be done for all protocols and all UIs simultaneously. We can either do it once per protocol backend, or once per UI. Once per UI would break the ability to log OTR messages or have them appear correctly in more than one UI (e.g. both Empathy and GNOME Shell). Every attempt at implementing OTR in Telepathy has had the plan to do it once per protocol backend; this implementation is no different. In practice, like most new features, everyone prototyped it in the XMPP protocol backend first, because that's the one that works best.
I think the approach that is most likely to yield results in a finite time is to get the XMPP implementation high-quality and mergeable first, then expand to the other protocols; then any implementation mistakes in the first implementation will hopefully not be repeated, and the rest will be a simple matter of "pretty much what Gabble did". Using a library for common code, or adding functionality to libotr, would be fine too, but that's an implementation detail.
Anyone interested in this could add similar glue to telepathy-haze to cover the various proprietary protocols (AOL, etc.). It might have seemed more natural to go for -haze first, but -haze uses libpurple, which is not really designed for things that aren't shaped like Pidgin, so it can be awkward to get right and doesn't make a great place for prototyping. The missing protocol backends after that would be telepathy-salut for link-local XMPP, telepathy-idle for IRC, and telepathy-rakia for SIP. I think it'd make sense to do -haze and maybe -salut. I'm not sure -idle or -rakia is necessarily worthwhile, but if people do use OTR on those protocols in practice, sure, why not.
(In reply to comment #87)
> Would it be possible to use the same code for the new gnome-chat application
> which will likely replace Empathy?
The majority of the glue between Telepathy and libotr (as exemplified here by patches to Gabble), and the design: yes, it lives in the protocol backend(s).
The UI: no, the UI code in Empathy is specific to Empathy. gnome-chat would need to provide a way to enable/disable OTR and mark fingerprints as trusted, and to be properly secure, it would need to display the notifications from libotr in a way that cannot be spoofed by contacts.

Hi
I am currently working on OTR support for KDE Telepathy. There are some
features we would like to have:
- otr policy settings
- a way to generate a new private key for account
- possibility to manage known fingerprints (trust/distrust)
- two additional ways of peer authentication (shared secret and
question-answer)
Realization of the first three points would require adding a new interface
to gabble. I imagine it as an extension of connection interface providing
settings individually for every account. Would using gdbus codegen just
like in case of the currently implemented otr channel be acceptable here? I
suppose that adding these features would mean some major changes in the
current implementation which is completely closed in the channel interface.
There are also things that need to be fixed as stated above:

You could make it go "next to" the Connection just like Xavier's code produces an object "next to" the Channel, yes.
(Unfortunately, the fact that, in general, telepathy-glib uses the deprecated dbus-glib instead of GDBus is not going to get fixed, unless someone with a lot more time available than me picks it up. See the various "Telepathy 1.0" bugs for details.)

Making behind-the-scenes C function calls between the Connection and Channel objects is fine.

Yes, I think that would be better than hoping they will be fixed later.
I consider those fixes to be merge blockers for these branches, because I don't want to add an interop and security feature that, on closer inspection, turns out to be non-interoperable or insecure :-)

Seeing as the compile process isn't well documented, it's very confusing for newcomers. If you'll also note, someone else asked if you could provide some build instructions on your blog post to help compile it.

You probably want python2. Build just fine on ubuntu 15.04, it just has a warning for a deprecated gnutls function, but you can ignore that with --disable-Werror (or make a fix).
sudo apt-get build-dep telepathy-gabble
./autogen.sh --disable-Werror
make
make install

I can confirm it compiles after fixing the depreciated function and forcing the Makefile to use python2.7 followed by making it read-only (keeps trying to put 3.4 in there).
So after I ran the make install I started up empathy, but was unable to use "/otr start". It claims command is not found.
I then read this:
> You need to set "enable-otr=true" in your CM parameters, otherwise OTR is disabled
No idea what a CM parameter is or where to set it, so I ran grep on all the files. Nothing says "enable-otr".
Can someone clarify where to put that line?

In regards to my previous comment. I discovered enable-otr is in /src/connection.c, once you get the right branch...
git clone git://people.
git checkout untested-otr
I also tried setting the default "FALSE" option to "TRUE". Still OTR doesn't work for me, perhaps empathy also needs to be patched (instead of just gabble). However Xaivers empathy branch no longer runs properly on my system due to changes in gtk, so I am unable to test the older version.
So, that's as far as I made it.

Anyone still working on getting this into released empathy ?
Thanks,

No idea - I've long migrated to software which cares enough about security not to have critical bugs opened for 5 years.

@Xavier: Can't you provide us, at very least, a small tutorial showing how to compile this with the latest empathy build? Because it doesn't work.
If not - I donated years ago for this to be implemented, so I'll want my money back. :P

"it doesn't work" is too vague plus Bugzilla is not a support forum for general software development question. There are many pages out there which explain how to compile software... Thanks for your understanding.

I would like to point everyone to this bug that I just opened
https:/
It seems there is a better alternative to OTR now, called OMEMO. Maybe the focus should be on implementing that, rather than OTR.

#259 |
I don't think that OTR and OMEMO are mutually exclusive in any way. Besides, looking at the bug age it doesn't seems like there are much of efforts which could be "focused" anyway.

Worth mentioning that Xavier Claessens's never implemented patch is now likely vulnerable anyway...
https:/
Upstream libotr has already addressed the vulnerability, so any attempts at this should be sure to implement the latest version without the memory bug.
@Andre Klapper: All I asked for was a quick tutorial on how to build it. However, as the years have continued to go by, I am now uninterested and have stopped using most GNOME telecommunication products completely due to lack of documentation and security. ¯\_(ツ)_/¯

1) GNOME is a destkop has nothing to do with communication, you can install any application under gnome
2) GNOME is open-source software not a product
From dictionary
product - "an article or substance that is manufactured or refined for sale"
3) There is plenty of documentation
4) Major part of open-source software is a contribution developed by people in their spare time
5) I believe it's of very minor importance what you use or not, or do in your life for the people signed up for this bug issue
Maybe no one wanted to spend time on this feature for a good reason.

KDE Telepathy has an implementation of OTR, There's a proxy component that handles adding/removing the encryption before passing it to the chat window.
It's in https:/
There's also some UI level code in https:/
A quick skim of the #includes suggests otr-proxy mostly just depends on TelepathyQt and not strongly on other KDE telepathy components.

Mostly no one wanted to spend time on this because development on Telepathy stalled in 2014. It was largely being maintained by Collabora, and their funding dried up.
I do have the ability to merge code to telepathy, but I don't have time to work on a feature this complex.
Someone else will need to volunteer to implement this.

Could someone explain how OTR request is duplicate of OMEMO request?
As far as I am aware, Empathy supports multiple instant messaging protocols which all support OTR as it's not tied to any specific protocol. On the other hand OMEMO is XMPP-only and not yet formalized XMPP extension, so by considering this as a duplicate I believe users of those other protocols are left without option for end-to-end encryption.

Yeah, encryption is a must for me, too. This the only reason using Pidgin instead of telepathy for me.
