Cyph was founded by two former SpaceX engineers to meet their own high standards of what chat should be: completely private and delightfully dope. Try out a chat I created via: https://cyph.im/st1OJhH#j1a3uyD

@bramk Nice, thanks for the post! That chat will only work for the first person who clicks it, by the way (by design), but hope the rest of you like our 404 page!

@bramk Yep, no group chat for now, but we should have that out by early next year.

I spy a Christopher Walken cameo (that landing page is kind of intense). The site lacks any details on the encryption or how it works. Strange for a service that's entirely dedicated to privacy and security.

@rrhoover Yep, that's Walken; @thebeefytaco got a little carried away with the video lol. Details are coming soon! This version of the landing page was pretty rushed, but we figured we'd just get it out there and worry about the content after the fact since our actual product is pretty good now. Basically, though, we're using OTR and authenticating with a randomly generated shared secret that we put in the URL fragment (visible only to the client), which means that our threat model for a server-side mitm is essentially that an attacker would need to compromise both the Cyph backend *and* the users' SMS/email/etc. (This ignores the possibility of an attacker who's hacked our backend brazenly pushing malicious code out to the frontend, but we have a solution for this problem in the works.)

hmmmmm interesting little quirk. don't know if it was intentional but is it possible that the reason behind using cyph.im for the chat links versus the .com is to foresee an event where the government takes over the .com but can't for the .im?

@taylorhou Hmm, that's an interesting point. I hadn't thought of that (.im just seemed shorter and more convenient), but that's definitely possibly a good reason to keep using the .im domain!
