I wonder if we can make a chat app that doesn't use encryption but hides your messages inside random words. The solution should be saved locally on your device.

Encryption is defined as "the process of converting information or data into a code, especially to prevent unauthorized access."

What you describe is the same thing just not cryptographic.

Installed as a signed app...?

How would chat control even work, with federated and decentralized networks? This is the reason you should not use signal. Moxie wants everyone to be in a closed loop, tightly controlled by his decisions. Matrix ftw!

Moxie hasn't worked at Signal for a while now

Format-Transforming Encryption (FTE) is what you're looking for--it ensures the resulting message isn't vulnerable to cryptanalysis techniques while enabling encoding of a message in arbitrary formats [0], including a blog post or text message. The authors of the source use it specifically to hide messages in semantically-correct network protocol packets, but it applies just as well to text.

No one should remove from us the right to privacy in chat rooms. Otherwise, PGP might become cool again, or I bet that there will be new ways to chat without mass surveillance.

> Otherwise, PGP might become cool People need convenient access to PGP. If their App Store removes all PGP apps then they might have to upload their privatekey to a PWA. And then no one's any better off. If the everyman is forced to choose between being surveilled or using PGP, I reckon I know what he'd choose regardless.

There's no reason email clients can't make PGP keys easy, proton actually makes it quite easy to add a PGP key for an email address.

> Under the guise of protecting children, the latest Chat Control proposals would require mass scanning of every message, photo, and video on a person’s device, assessing these via a government-mandated database or AI model to determine whether they are permissible content or not. This is pretty terrifying, although not unexpected. Given Germany's aggressive crackdown on speech I wouldn't feel too optimistic. If the…

German speaking here: People here in Germany do not want to think about just how bad our constitution really is designed. We only get free speech lte, There's no fruit of the poisonous tree doctrine leading to constant prosecutorial overreach and illegal searches[0] that are later ruled illegal but with on effect and our public prosecutors are so much lacking in independence that they aren't allowed to issue european arrest warrants [1]. But I've heard people tell me with complete conviction how great our constitution is. I can't even bother arguing about it anymore.
