Delta Chat may be criticized for not being the most secure messenger in some sense or not the most feature rich. When it comes to interoperability, however, our efforts and collaborations are the biggest game in town, no? The two biggest sets of internet standards revolve and operate at massive scale around E-Mail and the Web. Our approach fully engages and takes up these extremely impactful sets of standards, and reliably rewires them into a modern UI #deltachat #webxdc #chatmail #xkcd927

Did you know that Delta Chat is the only mature, cross-platform secure messaging app that does not use or need a key server?

Signal, Matrix, Proton, Whatsapp all effectively operate key servers that reveal the cryptographic identity (a very strong identifier) behind an address.

Delta Chat uses decentralized specs and protocols that reveal your cryptographic identity only to those you choose to interact with. Nothing can be publically queried.

@delta is it supported to self-host an email server for Delta Chat and have functional push notifications with the iOS app?

Delta Chat is an in-between project: often ignored as a messenger by e-mail companies/experts and then ignored by messenger companies/experts because of its use and interoperability with e-mail. As Heinz von Foerster once said: "If you are doing something genuinely new then don't ask the experts. If you do something that has already been done, then, by all means, ask the experts." FWIW many experts have verified Delta Chat's security mechanics https://delta.chat/en/help#security-audits :)

The "webxdc evolve" project is now official and was just announced from one of our early followers and advisers, @ansuz , but it's not just a boilerplate announcement! Ansuz dives deep starting from his yearslong cryptpad maintainership history, his early involvement in #webxdc up to the present and future .... Very good reading if you want to understand some.foundational considerations around evolving an end-to-end encrypted, decentralized web app platform ...

Seems the french surveillance practises (Hadopi) identifying people behind IP addresses have been legalized by a top EU court. Fwiw #chatmail servers remove any IP address traces after two days and collect no personal data whatsoever. Maybe it's time for a french themed chatmail server similar to the de,pl,us ones? https://delta.chat/en/chatmail

A wild community experiment that can not but fail? Probably but whatever, welcome to massive multi-device usage of #deltachat on #chatmail :) it's an account not shared between your own devices but between all devices who can import the backup file that is currently circulating .... Bringing you an anonymous e2ee encrypted forum without individual user identities, with autodeletion from server after a week .... also adressable wirh e2ee messaging .... #DepartmentOfCrazy

For those who like to focus on #security an honest question: which other messenger has, like #deltachat in the last 13 months, received and addressed two independent security audits and one security analysis, all three from renowned auditors and researchers?

Apart from the default #chatmail server advertised on our onboarding page there are at least three other stable open-signup servers whose operators cooperate to ensure stability, see this new page covering background such as funding, trust etc https://delta.chat/en/chatmail

Messaging transports better be dumb and do the bare minimum to get the job done for end-to-end encrypting apps. Compared to #matrix homeservers #chatmail servers are two orders of magnitude more dumb, consume two orders of magnitude less resources and are blazing fast and don't require extra (central?!) identity and integration servers. With delta all intelligence, including general purpose https://webxdc.org/apps and protection against compromised networks and servers, lives on the end device.

"but e-mail !1!!!" Is probably still a number one objection from experts and power users who refuse to fathom that e-mail protocols are a viable option for instant messaging even if it demonstrably works, is fast and secure :) We'd be happy if someone engaged in a proper comparison with xmpp and matrix specs and impls, really the only three messenging protocols deployed and implemented at scale. (Can't compare that with Signal or WhatsApp which don't have wire specs!). https://github.com/deltachat/deltachat-core-rust/blob/main/standards.md

How many people do you know that have lost their messaging history on Whatsapp or Signal, photos etc during mobile phone transitions or breakage or through other shenenigans?

With #deltachat you can:

• export "everything" to a file and import it on any of the many different devices

• or just setup a second device through a QR code scan -- which was happily discovered here after an accidental factory reset https://libranet.de/display/0b6b25a8-2066-0695-ca24-081964494389

The last 1.44 release round did not only contain a lot of UI/UX milestones but also 20 security fixes based on a deep analysis from Yuanming Song and colleagues of the Applied Cryptography group at ETH Zuerich https://delta.chat/en/2024-03-25-crypto-analysis-securejoin

Hi folks at @briar @delta and @Jami .
I need your help and hints, please.

Can I (easily) embed one of your communication protocols in a React Native + TypeScript app?

I'm creating an app (TKCompanionApp at @fdroidorg) that is currently as strong in privacy as possible (no permissions at all, not even Internet!), but I would like to allow users to directly share data and I'm wondering which is the simplest way to do so, respecting their privacy.

The default setup of #chatmail is for open signups (anyone can get an address) but some operators implement a private signup protocol and that's fine and easy enough to do because https://github.com/deltachat/chatmail/ is a small machine.

Chatmail addresses should be abundant and safe to use for anyone , and cheap to operate with basic skills .... A few thousand chatmail routers might already cover adresses for 10 billion people, with less resource/energy usage than a single VC funded LLM startup :)

#deltachat just got four major usability improvements as the 1.44 releases are rolling out
💗 Reactions on all platforms
💗 iOS Push notifications
💗 Multi-account desktop sidebar
💗 share invite links via other messengers. Enjoy :)

Given the experiences of the last decade it's healthy to distrust #decentralized tech if

• it's mainly developed by a centralized power structure
• the involved technology is very complex
• there is coin or VC funding involved

#deltachat has 1/100th, if even that, of what other popular messenging projects have in terms of moneys. But our distributed top-notch expertise in UI, crypto, networking tech and our federated collaborative practises across these concerns, try to make up for it ...

News from the machine room: the pure #rust end-to-end encryption engine, "rpgp", saw quite some work and a new release in recent weeks and now @hko released a higher level "rpgpie" interface for application developers ( see https://fosstodon.org/@hko/111997998005869515 ) which also powers running the IETF #OpenPGP #interoperability test suite quite successfully .... Delta Chat's security-audited encryption engine is in fact used from several other projects and in other contexts these days and we are happy about it!

In whichever area of #deltachat related developments you look, you will find different people and communities -- even if there are several individuals who appear in multiple contexts as key contributors or drivers. There is no single person who gets to decide about everything even if we do have lead roles for particular aspects. Our experimental community approaches respect Convays Law: https://en.wikipedia.org/wiki/Conway%27s_law -- meaning: our #decentralization tech will be only as good as our social practises

Testing #DeltaChat, pretty cool!

delta, 3 months ago to random

Was an eventful and enjoyable #offdem24 and #fossdem24 .... Ranging from intermingling with people operating security-sensitiv helplines using #chatmail to discussing email standards like the evolving openpgp cryptorefresh ... And then several more underground happenings which might lead to even more surprises than are already developing .... with many of us agreeinf and appreciating that we are rather engaged with lots interesting communities and folks rather than corporate structures.
