    There's probably at least 100 people who could code both Diffie-Hellman and ChaCha20 from memory. That's all you need for nation-state proof end-to-end private messaging. Banning it, or mandating backdoors in cryptography, are pointless when the bad guys can do that anyway.

        I can do multiplicative group DH and ChaCha20-Poly1305 from memory. I feel less confident about ECDH, but maybe with practice.

        FFDH with a 4096-bit group is probably more secure than ECDH anyway, if you worry about Post-Quantum risks.

        The only way to stop a bad guy with crypto is a good guy with crypto.

        Diffie Hellman was a part of our syllabus at University of Pune. So expect ~5000 students who can code it by heart 😂

        the point is that, to the nation-state, the civilian population is also the enemy

        the crazy bizzaro-world thing to me is that the Republicans used to warn about government "big brother" type overreach like this... now they're the main culprits.

        Which do you think is more likely? 1/ Nobody in the government understood that 2/ Surveiling only "bad guys" isn't the goal
