The only one, that is maintained and developed is probably #Emacs-#Jabber:

codeberg.org/emacs-jabber/emac

It's fun, but I don't use it, because it's missing most modern #XMPP features, such as MAM, #OMEMO, message replies, message reactions…

If I knew a little bit more of #Elisp — and had more time at hand…

Summary card of repository emacs-jabber/emacs-jabber
Codeberg.orgemacs-jabberJabber/XMPP client for Emacs (fork of https://github.com/legoscia/emacs-jabber.git)

There are no known security issues with "Siacs OMEMO" / OMEMO v0.3¹ despite of what some very loud Signal fans would like you to believe. It has been audited by a third party² who took a longer look at it than all of the Signal fans combined.

Yes, #OMEMO v0.7+ (or TWOMEMO 😜) is a cleaner spec with more features (most notably Stanza Content Encryption). That’s why we wrote it. I’m a co-author. That doesn’t mean v0.3 is insecure.

@signalapp no it's not.

Being a #centralized, #SingleVendor & #SingleProvider solution subject to #CloudAct makes you inherently vulnerable by your own choice and thus trivial to shutdown compared to real #E2EE with #SelfCustody of all the keys and true #decentralization as well as #SelfHosting (i.e. #PGP/MIME [see @delta / #deltaChat et. al.] and #XMPP+#OMEMO [see @monocles / #monoclesChat et. al.]!)

And don't even get me started on you collecting #PII (espechally #PhoneNumbers) for no valid reason, (thus violating #GDPR & #BDSG)...

But yeah, I'll be patient to shout "#ToldYaSo" to your annoying cult of fanboys!

@Andromxda @mollyim no it's not bs and fanboying @signalapp isn't going to change that.

If #Signal was secure it would be the #1 comms tool of organized crime...

Real professionals use #SelfHosting capable, fully #FLOSS'd solutions like #PGP/MIME & #XMPP+#OMEMO.

It's just me reading the room: Cuz #ComSec isn't done woth "JuSt UsE sIgNaL!" and everyone who claims so without pointing out #OpSec, #InfoSec & #ITsec is BSing hard.

  • The cold hard truth is that #TechLiteracy is irreplaceable and the only solution to it is to actually teach normies how to "get gud" with stuff like PGP.

Fortunatelty, @thunderbird and @tails_live / @tails / #Tails and many other tools make that easier than ever before.

@walkinglampshade @jrredho @fj It's basic #InfoSec, really:

Thus #Signal fails at protevting #Journalists and theor sources because they do have that data and can be #subopena'd for it if they don't already provide #BulkSurveillance & #LawfulInterception #API|s to comply with #CloudAct. (Or are you guys so naive and believe @Mer__edith will risk dying of old age in jail for non-paying users?)

  • This entire "thread vector" just doesn't exist with #XMPP+#OMEMO nor #PGP/MIME!

And if you believe "this won't ne used/abused me because I'm from 'Murica!" and point at #ANØM as an example, then you really ignored all tze #Cyberfacism since 9/11…

@froge @fj I'm not replacing @signalapp with "random tools" but good options.

Like @delta & @thunderbird as well as @monocles / #monoclesChat & @gajim which work flawlessly over @torproject / #Tor using @tails / @tails_live / #Tails and @guardianproject / #Orbot respectably.

Considering the costs of even acquiring and upkeeping an #anonymous #SIM, I'd rather pay €2 p.m. for #XMPP+#OMEMO and #PGP/MIME-supported #eMail with the option of self-custody than $2,50+ p.m. just to keep a phone number.

Or is anyone here expecting @Mer__edith to risk jail for life amd not comply with #CloudAct?

It stenches like #ANØM, because NOTHING IS FOR FREE and running a #VCmoneyBurningParty is expensive...

Infosec.SpaceKevin Karhan :verified: (@kkarhan@infosec.space)@osman@hachyderm.io If your #OpSec, #InfoSec, #ComSec and/or #ITsec relies on @signalapp@mastodon.world and/or @Mer__edith@mastodon.world [risking jail *or worse*](https://web.archive.org/web/20210908180219/https://twitter.com/thegrugq/status/1085614812581715968), you fucked up! - If #Signal was secure, it would've been shutdown like #EncroChat & #SkyECC. Seriously, to me #Signal stenches #Honeypot like #ANØM & #CryptoAG. - All Signal fans do is #FUD #PGP/MIME and#XMPP+#OMEMO which are truly #decentralized and allow real #SelfHosting as well as #SelfCustody for complete control of all the data and keys... That's why I get people setup with it!

Очередной скандал из ничего, не имевший бы оснований, если бы не прибегнули к откровенному вранью. Как всегда о злой и страшной России, якобы имеющей доступ к данным мессенджера #Signal

советник главы Белого дома по национальной безопасности Майкл Уолтц случайно добавил в закрытый чат, созданный в мессенджере Signal, редактора издания The Atlantic Джеффри Голдберга. В чате обсуждались вопросы, связанные с началом военной операции США против йеменских хуситов, используемое вооружение и прочая информация под грифом «совершенно секретно». В переписке участвовали министр обороны Пит Хегсет, директор ЦРУ, глава Национального разведывательного управления и другие высокопоставленные представители силовых структур.

Вот это враньё, на котором вертится весь скандал:

Несмотря на то что Signal использует двойное шифрование и считается одним из наиболее защищенных мессенджеров, давно известно, что спецслужбы многих стран, включая Россию, имеют доступ к его данным.

Не говоря уже о том, что Signal почему-то именуется «коммерческим мессенджером».

Именно криптосхема, протокол #e2ee, из Signal Messenger используется в #Viber, #WhatsApp, #Skype, #GoogleDUO и ряде других системах гарантируя «сквозное шифрование».
Включая тот самый #OMEMO для #XMPP/#Jabber, что пришёл на смену #OTR.

А сам по себе Signal Messenger считается не только каноничной реализацией этого протокола. Но и другого подхода — когда сервер не обладает метаданными кто же именно и кому пишет.
Т.е. когда владельцы сервиса не знают какие именно пользователи между собой в 3 часа ночи обмениваются сообщениями и с какой интенсивностью.

Этот подход называется sealed sender И многократно проверен на корректность академическим сообществом, ровно так же как была проверена криптосхема (протокол) Signal.

@fj I still think @signalapp has fundamental flaws like demanding #PII (#PhoneNumbers can't be obtained anonymously around the globe and are trivial to track down to devices and thus users), being subject to #CloudAct as an unnecessary & 100% avoidable risk as well as #Shitcoin-#Scam shilling (#MobileCoin) and it's #proprietary, #SingleVendor & #SingleProvider nature that makes it inferior to real #E2EE with #SelfCustody like #PGP/MIME & #XMPP+#OMEMO!

@osman If your #OpSec, #InfoSec, #ComSec and/or #ITsec relies on @signalapp and/or @Mer__edith risking jail or worse, you fucked up!

Seriously, to me #Signal stenches #Honeypot like #ANØM & #CryptoAG.
