Based on the title, I read this article thinking I was going to read a 'master vulnerability' or weakness of some sort in all major crypto implementations.

I was ready to say 'well actually - as long as you have perfect forward secrecy and maybe a double rachet you can make it virtually impossible to break the encryption at scale blah blah blah', like a good little armchair crypto parrot would.

But instead, I learned a little something new about how cryptography studies work. Thank you HN!
