How Twitter could (somewhat) fix their encrypted DMs
As I wrote in my last post, Twitter's new encrypted DM infrastructure is pretty awful. But the amount of work required to make it somewhat better isn't large.
When Juicebox is used with HSMs, it supports encrypting the communication between the client and the backend. This is handled by generating a unique keypair for each HSM. The public key is provided to the client, while the private key remains within the HSM. Even if you can see the traffic sent to the HSM, it's encrypted using the Noise protocol and so the user's encrypted secret data can't be retrieved.
But this is only useful if you know that the public key corresponds to a private key in the HSM! Right now there's no way to know this, but there's worse - the client doesn't have the public key built into it, it's supplied as a response to an API request made to Twitter's servers. Even
