So, I have a Threema license, but from what I’ve seen its encryption isn’t post-quantum. Signal’s encryption seems the strongest. I host my own matrix server.
Also, I kind of don’t care where the servers are or which provider it is. Everything is encrypted anyway.
OK, and how is that different from the other chats?
You do know that at least Signal and Matrix use pretty much the same crypto, right?
And Matrix can be self-hosted, so I don’t need to worry about what they can see anyway.
On this point alone Matrix appears more secure than Signal…
And Threema is Switzerland-based, so by default it’s more trustful than a USA-based company.
The metadata is really important especially if you or anyone you talk to ends up being targeted. 95% of intelligence work is mapping out adversaries’ communications networks…if you have that, you don’t need to decrypt the contents because you already know who is talking to who. The federation of metadata alone is reason to avoid matrix for anything important.
Thank you for being one person in this thread that actually read and understood my comment.
A bunch of comments repeating “Signal is the most secure because I said so” was not helpful.
I just saw your reply to me and was about to say the same thing, but they worded it perfectly. And I did mention metadata as a key point in my original post.
