[Goffi]

Great, congratulation for this amazing work. Is there any web page with this announce that we can link ?

>urn:xmpp:omemo:2 namespace [3].

>small protocol flow details of the OMEMO specification are handled by
>python-omemo as well.
>
>
>Key properties of the library:
>
>- Seamless support for both versions of the OMEMO specification at the
>same time. The library transparently handles compatibility between the
>two versions, i.e. identity keys, device ids and trust are shared
>appropriately. The protocol version to encrypt a message with can either
>be selected explicitly, or given as a priority, to e.g. use the new
>OMEMO if available, and fall back to the old OMEMO if not.
>
>- Handles bundle and device list, making sure the published data is
>always in sync with the local data.
>
>- Handles small protocol flow details, like sending automated empty
>messages in response to a key exchange or to prevent staleness.
>
>- Provides an easy way to integrate any sort of trust system - be it
>simple manual trust, BTBV, TOFU or something more complex.
>
>- Thin and straight-forward public API - OMEMO doesn't have to be
>complicated :)
>
>- Optionally reads/verifies and builds ElementTree XML structures for
>you, so that you can keep your codebase even thinner.
>
>- Clean, modern, fully-typed Python 3 with thorough API documentation.
>
>- Very easy to get started with - provide a simple key-value storage,
>implement some methods to upload/download bundles and device lists from
>PEP, and you're pretty much set!
>
>
>This library aims to enable client developers to equip their clients
>with OMEMO support without understanding all of the nasty cryptography
>or protocol flow details. Please give it a look, send me feedback and
>consider it for your Python-based client :)
