Yes

Here: https://github.com/dino/dino/tree/feature/omemo1

nice, that means the libsignal-protocol-c fork is functional as well?

gkdr avatar Dec 02 '20 22:12 gkdr

@gkdr: First, I can not confirm that current libomemo supports a perfect OMEMO 0.3.0, only you can confirm it.

About OMEMO 0.4.0+, I am not sure that the omemo1 branch of Dino is up-to-date. It is important to create a new libomemo branch for OMEMO 0.4.0+ or better, I think, a new repo, for example "libomemo-v2" or other...

@mar-v-in: Please talk with @gkdr.

Thanks in advance.

libomemo-c should work, but afaik it was not thoroughly tested with for compatibility any other implementation yet. When operating based on libomemo-c, you can implement omemo 0.3.0 and 0.4.0+ at the same time so that your client remains fully backwards-compatible. This is what is implemented in omemo1 branch, but again, nothing of this was thoroughly tested and you'd be the first client to implement this in production.

oh, nice, thanks for that! the changes look like i can probably plug it into my signal-protocol-client-code with little adaptations. i can also start implementing the pure xml stuff here, but will think about how to include the forked signal protocol since it's now part of the omemo spec.

Is this fixed now (after 6f153c086b1b5618fca347f420fe50a8f73e14d5 and further changes last year)?

@hades: Sorry for the delay, it does not support OMEMO 0.8.3, it is only 0.3.0.

And "XEP-0454: OMEMO Media sharing" is missing too:

  • https://xmpp.org/extensions/xep-0454.html

Maybe some guys can look it?
