NEW: XEP-0518 (Payment Required)

by Daniel Gultsch

Version 0.1.0 of XEP-0518 (Payment Required) has been released. Abstract: This specification defines an XMPP protocol extension that enables services to require payment before granting access to a resource. It provides a payment-system-neutral invoice format built on payment URIs (such as the RFC 8905 payto scheme), supporting multiple concurrent payment options, from bank transfers to transfers over distributed ledgers or instant-settlement networks, and integrates with the existing CAPTCHA challenge mechanism defined in XEP-0158. Changelog: Accepted as Experimental by council vote on 2026-07-07 (XEP Editor (dg)) URL: https://xmpp.org/extensions/xep-0518.html Note: The information in the XEP list at https://xmpp.org/extensions/ is updated by a separate automated process and may be stale at the time this email is sent. The XEP documents linked herein are up-to- date.

UPDATED: XEP-0515 (TLS Channel-Binding Downgrade Protection)

by Daniel Gultsch

Version 0.1.1 of XEP-0515 (TLS Channel-Binding Downgrade Protection) has been released. Abstract: This specification provides a way to secure the SASL and SASL2 SCRAM handshakes against channel-binding downgrades through TLS version downgrades. Changelog: Fixed typo in Bind 2 namespace (XEP Editor (dg)) URL: https://xmpp.org/extensions/xep-0515.html Note: The information in the XEP list at https://xmpp.org/extensions/ is updated by a separate automated process and may be stale at the time this email is sent.

UPDATED: XEP-0066 (Out of Band Data)

by Daniel Gultsch

Version 1.6 of XEP-0066 (Out of Band Data) has been released. Abstract: This specification defines two XMPP protocol extensions for communicating URIs, one for use in XMPP message stanzas and the other for use in a structured request-response interaction via XMPP IQ stanzas. Among other things, this enables one entity to inform another entity about a file that is available at an HTTP URL. Changelog: Twenty years later, strike section 6's SI suggestion (dwd) URL: https://xmpp.org/extensions/xep-0066.html Note: The information in the XEP list at https://xmpp.org/extensions/ is updated by a separate automated process and may be stale at the time this email is sent.

29th XMPP Summit

by Daniel Gultsch

Good morning the 29th XMPP Summit is fast approaching. It is our first attempt at an online only Summit and will be held on Friday 4 September and Saturday 5 September 2026. If you intent to attend please add yourself to the participants list¹. Adding yourself might also motivate others to participate itself. Please find the time to do so even if there is no "limited seating" or other constraints. We are also looking for topic suggestions. We will maintain the unconference style of offline summits (meaning participants can bring their own topics) but for time constraints we will do the topic suggestions and topic sorting ahead of time. Meaning what usually happens on the white board in the first hour of a traditional summit will now happen on list. Please go ahead and propose topics and include a short pitch. Additionally please add the topic to the wiki.² (If you someone only suggests it here I’ll try my best to add it to the wiki myself.) I will close the topic suggestion round on Thursday 27th so we will have about a week to vote on the topics. (which will determine the order of the four topics we'll be discussing during the Summit) cheers Daniel ¹: https://wiki.xmpp.org/web/Conferences/Summit_29#Participants ²: https://wiki.xmpp.org/web/Conferences/Summit_29#Proposed_Topics

DC EDIC

by Matija Šuklje

Dear all, I’m a little bit involved with the DC EDIC (Digital Commons European Digital Infrastructure Consortium) and it seems like it could be interesting for the wider XMPP community. From its mission: > DC-EDIC develops, maintains, and scales digital commons for Europe, pooling > resources across member states to reduce technological dependency. <https://digital-commons-edic.eu/> The about page summarizes it pretty well and in short too, so I won’t copy- paste it here. They are setting up an EU STF similar to (and together with) the German Sovereign Tech Fund/Agency to sponsor development and maintenance of important software. While the first project is planned to be about a “collaborative workspace flagship”, communication and messaging is already explicitly part of that. In my opinion, DC EDIC could prove to be a big vector for getting FOSS, interoperability and (open-)standard-based formats and protocols into (European) public administrations and also to get funding for it. There are things both in the mission and the future project criteria that I feel resonate with the XMPP ecosystem very well and IMHO it would be a damn waste not to keep an eye on it and reach out. For example, there is currently a _call for experts_ out, where not just countries in DC EDIC, but also FOSS communities may suggest topic experts. I suggest the XSF puts forward someone there: <https://digital-commons-edic.eu/news/2026-07-01-advisory-board-call-for-exp…> kind regards, Matija -- gsm: tel:+386.41.849.552 www: https://matija.suklje.name xmpp: hook(a)campfire.wheremymonkeyis.at matrix: @hook:kompot.si

Post-quantum security of OMEMO

by Chris Tsichrinis

Hello everyone, I keep reading about recent developments in the quantum computing field, with whatever this may mean for classic asymmetric encryption/key exchange algorithms. More specifically, it appears that both Google (Quantum frontiers may be closer than they appear <https://blog.google/innovation-and-ai/technology/safety-security/cryptograp…>) and Cloudflare (Cloudflare targets 2029 for full post-quantum security <https://blog.cloudflare.com/post-quantum-roadmap/>) have targeted 2029 for post-quantum migration. Both of these blog posts made me ponder about the post-quantum security of the OMEMO. I am not an expert on the field of asymmetric cryptography, but per XEP-0384 <https://xmpp.org/extensions/xep-0384.html>, OMEMO uses the X3DH key agreement protocol for key exchange and the Double Ratchet Algorithm for message encryption and decryption. From what I can grasp, Signal has developed the PQXDH key agreement protocol as a post-quantum secure variant of X3DH, while Double Rachet also seems to provide no post-quantum protection <https://signal.org/docs/specifications/doubleratchet/#harvest-now-decrypt-l…>. With that being said, I'd like to ask if there are any plans to update the relevant OMEMO standard in the future to make OMEMO post-quantum-proof and if not, whether OMEMO's post-quantum security is considered trivial or not. Thanks in advance
