Es wird bestes Demowetter geben. Die Sonne wird scheinen, die Temperaturen liegen aber um den Gefrierpunkt. Zieht euch daher warm an.
Nach der Auftaktkundgebung ziehen wir 2 km durch die Elberfelder Innenstadt zurück zum Hauptbahnhof zur Abschlusskundgebung.
So, I'm interested how the implementation of "Perfect Forward Secrecy" in Signal looks like, like does every messages has a different encryption key? or does it change over time like #whatsapp does? I tried to find any official documention of this, sadly did not find anything.
Thats why I'm asking, does anyone of you know smth about this and maybe can provide a link to a official source?
This is the encryption that they developed. Whatsapp and OMEMO (XMPP) use it as well. It has forward secrecy because if an attacker has the key for a message they can’t calculate the key for the key for the next message etc.
essentially, yes. There are two levels of encryption keys and they “ratchet” along (change). Only the lower level is used to encrypt the text so it’s much harder to figure out the other one.
Since Ig we all know this message which appears when the “keys” ig, changed
I don’t know if I fully understand you here.
To my understanding whatsapp does it like this too. The key changing must be the high level key, since the message means that it’s an unknown key (thus not yet trusted). From new install or new device.
Diffie-Hellman is only a key exchange protocol and does not provide forward secrecy. Imagine that my and your client figure out our shared secred (key) with DH, then encrypt our chat with that. If someone breaks only a bit of our traffic, then they can read newer messages as well.
Forward secrecy means that at any point messages are encrypted with keys that aren’t reused forever, which means if an attacker can intercept traffic and read a bit, or crack the encryption, that they don’t automatically get access to our future conversation as well.
Hallo miteinander, eigentlich sollte es ja gut funktionieren im Fediverse auf andere instances zuzugreifen. Ich hab einfach keine lust mehr auf Reddit und deshalb würde ich lieber hier unterwegs sein. Ich habe mir kbin.social als Startpunkt ausgesucht weil ich gutes gehört habe aber irgendwie schaffe ich es nicht wirklich auf andere Communities zuzugreifen. Ich habe jetzt de_EDV rausgesucht um zu testen ob ich überhaupt mit anderen interagieren kann. Würde es sich lohnen mir lieber einen feddit.de Account zu machen ind Ann man diesen Post überhaupt sehen?
Nein es ist egal wo dein Account ist. Solange der server einigermassen gut moderiert ist (also kein Zuhause fuer Spammer oder so), dann solltest du freie Bahn haben :)
Aw man, here we go again! Everything I post seems to end up on the top of Fedia's front page! I've got a lot of work to do before all 400+ posts from the original /r/FloatingIsFun are reposted here. @Jerry I hope I'm not messing things up too much.

@selfhosted Stick with Mastadon account or move over to Lemmy instance?
I'm currently self hosting my own mastadon instance, and noticed I can use the same account to post to Lemmy as well using mentions and the fediverse.
Is anybody else using mastadon to post to their lemmy instances? Would it make more sense to host a lemmy instance instead if I intent to post to lemmy more often than mastadon? Let me know your thoughts.
