I am very interested in this, too.

I'm also very interested. That's really a great feature.

would fit perfectly with the Conversations Android App, which also supports omemo

GreenLunar · 2016-08-06T15:09:44Z

See also OMEMO.js at cryptocat/cryptocat#178

herbsmn · 2016-09-09T03:37:54Z

What are the blockers you have that are preventing implimentation of OMEMO?

jcbrand · 2016-09-09T07:11:08Z

@herbsmn I currently don't have the time for it.

The XEP is now release http://xmpp.org/extensions/xep-0384.html

jcbrand · 2017-02-14T11:46:33Z

There is a pending GSOC Proposal for this feature.

ignatdoc · 2017-05-24T18:17:33Z

Maybe someone want to implement OMEMO support for bounty ? We can discuss )

jcbrand · 2017-06-27T11:24:05Z

Unfortunately converse.js didn't get any GSOC students this year.

There were three applications, but none of them made the cut. The decision was made by the XSF foundation and myself. What also played a role was that I wasn't able to find a backup mentor to help me this year.

This means that there's nobody working on OMEMO currently.

@ignatdoc Why don't you simply post a bounty on bountysource? The link is in the ticket description. The money doesn't get subtracted unless and until this ticket gets closed.

This applies to anyone else who wants to see this ticket move forward.

plambe · 2018-03-20T15:16:23Z

jsxc has a new OMEMO plugin:
https://github.com/jsxc/jsxc-plugin-omemo

I hope this helps since it's written in javascript.

Mrfuyu · 2018-03-27T19:27:59Z

Conversations now is encrypting with OMEMO by default, what can break communication. Would be nice to have this now also in Converse.js !

When receiving a PreKeySignalMessage, then a prekey has been chosen and should now be removed from the list of available prekeys in the bundle, so that a different device doesn't choose it as well. AFAICT, libsignal removes the prekey, so it's then up to us to regenerate it and republish our bundle. updates #497

OMEMO support has been added. Tested with Conversations.

muppeth · 2018-09-01T00:10:05Z

how do you enable it?

jcbrand · 2018-09-02T21:46:28Z

how do you enable it?

libsignal needs to be loaded and available. Then you will see a lock icon in the chat toolbar.

genofire · 2018-09-08T02:32:00Z

okay got it, just do a wget "https://raw.githubusercontent.com/signalapp/libsignal-protocol-javascript/master/dist/libsignal-protocol.js" and include it by adding <script src="/static/libsignal-protocol.js"></script> in html file. ;)

Is there any way of qrcode to scan for Conversations and co?

MatthiasKauer · 2018-09-20T02:14:02Z

I wanted to try OMEMO from https://inverse.chat/ or https://conversejs.org/.
I can't find the "lock" you mention above there, however.
Looking at the page source, I find:
<script src="3rdparty/libsignal-protocol-javascript/dist/libsignal-protocol.js"></script>
Unfortunately, that file gives me a 404.
Is there a problem with that link or am I just missing something?

jcbrand · 2018-09-20T07:27:21Z

@MatthiasKauer Should be fixed now, thanks for reporting.

MaggusK · 2018-10-23T08:22:37Z

@MatthiasKauer Should be fixed now, thanks for reporting.

sounds easy, but sorry, I could not find any lock icon, neither at https://inverse.chat/ nor at https://conversejs.org/ although libsignal is included and available.
(I use firefox 60.1.0esr (64-bit) on RHEL 6.10)

MatthiasKauer · 2018-10-23T08:57:35Z

It's fixed as far as I can tell. I happily used inverse.chat yesterday.

@MatthiasKauer:
I'm really pleased for you. Could you please tell me how to use omemo on this sites? As you can see on the screenshot there is nothing like a lock icon :(

MaggusK · 2018-10-23T10:22:27Z

obviously OMEMO encryption is only supported for XMPP IDs of the same server. I created a new conversejs ID and with this encryption works on conversejs.org. But also the conversejs ID does not work on inverse.chat as all my other IDs don't.
Is there anybody who can explain this?

jcbrand · 2018-10-23T10:37:54Z

obviously OMEMO encryption is only supported for XMPP IDs of the same server.

No, this is not true. OMEMO encryption is client-based and largely independent of the server (as long as it is modern enough to implement PEP).

I created a new conversejs ID and with this encryption works on conversejs.org. But also the conversejs ID does not work on inverse.chat as all my other IDs don't.

Both users need to use an OMEMO compliant client. What did the other user use?

MaggusK · 2018-10-23T10:46:34Z

Both users need to use an OMEMO compliant client. What did the other user use?

I always chat with the same other jabber.de user that is using conversations. If I log in with my new conversejs.org ID it works.
So, is there an explanation, why, if I log in with my jabber.de ID I can not send encypted messages to the same user with the same client?
I also tried to logout / login again, even to remove / add contact again.

As you can see on the screenshot above it also doesn't decrypt the received OMEMO encrypted messages from conversations.

jcbrand · 2018-10-23T11:00:00Z

@MaggusK I don't know. Maybe you have old cached JavaScript files? Clear your cache and then check again.

MaggusK · 2018-10-23T12:16:20Z

@jcbrand : I found out, there is also a jabber webchat at https://chat.jabber.de/ (using conversejs).
If I login with my jabber.de ID I can see the lock icon there, but an error occurs while sending a message: "Sorry, could not send the message due to an error. bundle is undefined". Unencryptet messages can be delivered. What ever this could be?! Seems there is a problem with the jabber ID.
Maybe this is also the reason, why the file adding icon isn't appearing.

NicoHood · 2018-12-01T08:23:57Z

How do I enable omemo in converse? Every message is unencrypted for me.

Edit: I used an untrusted device as option. But with a trusted device it still does not work in a group channel. Why?

licaon-kter · 2018-12-01T08:29:09Z

@NicoHood Not for groups yet.

Just 1:1 for now.

NicoHood · 2018-12-01T12:07:38Z

But then this list ist wrong:

orbitz · 2019-06-08T21:55:37Z

Is there any plan for converse.js to support group chat and OMEMO?

Neustradamus · 2019-12-11T09:46:25Z

@jcbrand: OMEMO works in groups if all users have OMEMO keys of all users in the group.

Can you look it?
