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

Re: [jdev] Announcing the release of python-omemo, with support for the new SCE-based OMEMO
Awesome work Tim! Congratulations on the release! Paul Am 11.11.22 um 15:49 schrieb Tim Henkes: After years of development I am stoked to announce the release of python-omemo - An open Python implementation of the OMEMO Multi-End Message and Object Encryption protocol! python-omemo [1] is an OMEMO implementation written from scratch with support for both the currently widespread eu.siacs.conversations.axolotl version of OMEMO [2] and the newest, SCE-based version under the urn:xmpp:omemo:2 namespace [3]. Notably, python-omemo is an implementation of the OMEMO _protocol_ and not just the cryptographic primitives, which means that many of the 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 :) [1]: https://github.com/Syndace/python-omemo [2]: https://xmpp.org/extensions/attic/xep-0384-0.3.0.html [3]: https://xmpp.org/extensions/xep-0384.html ___ JDev mailing list Info: https://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: jdev-unsubscr...@jabber.org ___ ___ JDev mailing list Info: https://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: jdev-unsubscr...@jabber.org ___
