If you read the recent _Against XMPP+OMEMO_ article, it might be interesting to come back and read its comment section there as well as the following article:

#XMPP #OMEMO #E2EE #Signal

Der Messenger #Telegram ist für eine sichere Kommunikation nicht geeignet - standardmäßig sind die Nachrichten nicht einmal Ende-zu-Ende verschlüsselt. Besser geeignet sind #Signal oder #Threema. Übrigens: Elon Musk ist das Paradebeispiel eines Trolls. Einfach ignorieren. 😉

Can anymany tell me how I'm "supposed" to use end-to-end encryption with XMPP?

As far as I can tell there are three totally different ways to do E2EE:

a)OTR : "[xmpp.org/extensions/xep-0364.h…](Not intended to be a current standard), or technical specification, as better (albeit, newer and less well tested) methods of end-to-end encryption exist for XMPP. "

b)OpenPGP: There are at least two different XEPs about it. XEP-0027 is obsolete, while XEP-0373 is "experimental" but hasn't been updated in almost three years.

c)OMEMO: "Experimental" and hasn't been updated in over two years.

Is there a way to do E2EE in XMPP which is neither deprecated nor experimental? What's the "Current stable" way to do it?

@protonmail The problem is more like "fiddling with the contents" or doing anything in transit.

Cuz I do #E2EE the way it's meant to be done aka. #SelfCustody of #Keys and not some #MITM'ing "Appliance"...

If you do 1 thing today, use @Tutanota and forward your #gmail and #hotmail to your new inbox. Take back your mailbox!

For your second thing, switch to an encrypted messenger like #Signal and get your friends and family on it. It's so easy.

Today, two open letters from academics on the scientific arguments against the current #CSS (client side scanning) initiatives have been released:

* The first (in English, internationally coordinated) one is online at tinyurl.com/CSAScientistsLette… and still open for additional signatures.

* The second (in German, by #Austrian academics) one is online at ins.jku.at/chatcontrol/ and explicitly includes law experts in addition to the arguments from a security, privacy, and AI perspective.

This debate is expected to gain new steam with #Spain taking over the EU council presidency, given recently leaked statements like "Ideally, in our view, it would be desirable to legislatively prevent EU-based service providers from implementing end-to-end encryption" (wired.co.uk/article/europe-bre…).

Please boost on any channels you deem adequate. The discussion is still open, and we have little time to bring it to a more rational level.
