If an attacker decrypts one of your message, they can decrypt all your messages if you don’t have Perfect Forward Secrecy so it’s very important. With PFS, if the attacker decrypts one message, only this one will be decrypted
In case Signal doesn’t work or my contracts didn’t receive the message I use XMPP with OMEMO encryption (I have a simple Prosody server on my home server) and DeltaChat (everybody has an e-mail address)
DeltaChat is only to tell people "hey I sent you a message, answer! 🙂
When I have no WIFI or Internet access I still have Briar but I use it rarely
What’s PFS?

Thank you! Signal does have PFS, right?

Yes, the Signal protocol uses the Double Ratchet algorithm to provide PFS. Over all it is the best messenger app there is currently in terms of privacy -> https://soatok.blog/2024/07/31/what-does-it-mean-to-be-a-signal-competitor/
Even if Signal cannot access anything you share on it, it has major flaws for me:
By the way my nickname is Saejima, a friend of Onizuka and Danma lol 😂
Thx. What do you use instead of Signal then? Threema maybe?
Ah LOL didn’t notice the name. Nice one.

Wow that’s overkill. Thanks
