"the best an attacker can do is traffic analysis and denial of service...? "
That's already a lot. If the evil secret police knows when and with whom you texted, then they don't even need to know the text of the messages, to link you to the opposition. And then just extract you and then the password with force to get the rest.

- hutzlibu 4y agoIt is, but encryption is still useful, as not everyone on this planet is in reach of evil secret police and their goons and wrenches are limited.
- e12e 4y agoIt certainly is a lot. It's enough for a drone strike. But almost by definition, if you have a back-end, there will be meta-data. There's been a few attempts at getting around it, with "one-to-many" (eg opaque PGP posts to Usenet groups), Mixmasters (remailers) or onion routing. None are AFAIK truly practical with a state-level adversary. e2ee is a good start, that doesn't mean you don't need to analyse the risks.
