@delta Reminds me of SimpleX, if you can add quantum-resistant encryption and easy multi profile management and throwaway (incognito) profiles like simplex then the privacy and anonymity features would probably be on par and I'd consider switching to get away from the far right dev team.

I'm glad to hear that I will have to take a closer look. Classical encryption is still a deal breaker though because of Store Now Decrypt Later attacks, SimpleX uses the double ratchet algorithm developed by signal, maybe DeltaChat could too idk if that's helpful.

@ambiguous_yelp @rakoo @delta PQC is obviously desirable for a privacy-centric messaging service but running one of shor's algorithms for breaking RSA and ECC is still a way away. for an n-bit RSA key, you'd need 3n qubits. RSA keys are 2048-4096 bits (hopefully the latter). the current largest circuit-based quantum computer is ~1200 qubits AFAIK. that is 10x less than you'd need to break a recommended size RSA key.

even then, as far as i can tell, current PQC is mostly a guess as to what quantum computers will not have algorithms in class BQP to break them.

if your threat model truly is nation states who are actively recording your communications with near-future access to that amount of error-corrected quantum compute then sure. but for someone more concerned with big companies invading their privacy, platforms without PQC do their job perfectly well (as long as their cryptosystem provides perfect forward secrecy, IND-CPA, IND-CCA1/2, though i'm not a cryptographer so don't quote me on that).

As an anarchist I think that we should all consider the state an adversary because the state is a threat to everyone's liberty and survival: they protect ecosphere destroying businesses and risk global extinction on the only planet known to host life.

When someone acts to rescue non-human creatures being tortured and murdered its that state that will come and lock up the rescuer

Qubit count seems to be exponential[1] I think its reasonable to expect quantum supremacy possibly within the next 10y

@ambiguous_yelp if a quantum-capable nation state is targeting you, PQC is the least of your concerns. it is, imo, a nice-to-have with the current state of things.

as for qubits, it is hard to tell how they're growing at this point. it is purely speculative and i reckon the public perception of growth may be influenced by marketing.

PQC would be ideal, and it isn't all too hard to use an existing implementation. but the fact that a messaging service doesn't have it isn't at the top of the list for required features to protect your privacy against big corps.

@novet

Afaict simplex has all the same privacy and anonymity benefits as deltachat, and it might even have more features: simplex has calls, live-text, file transfer, voice messages, out of the box tor integration with client settings and onion address support, tag-sorting for chats, GUI theme customization and export including custom photo backgrounds.

Given that both simplex and deltachat have very similar threat models and architecture its difficult to see why anyone would choose to use deltachat over simplex when simplex has quantum resistance and deltachat does not
