Some services are slowly developing post quantum resistant protocols for their services like Signal or Tutanota. When will this be a thing for the web?

Wouldn't HTTPS automatically support it once TLS does?

It depends if the new encryption methods are compatible with the key exchange mechanism.

Considering this proposal is used for the key exchange, they definitely need to update both the client side and server side part to be able to make use of it. That's the kind of thing that may take years but luckily it can fall back to older methods.

It also needs to be thoroughly vetted so that's why it's a hybrid approach. If the quantum resistant algorithm turns out to have problems (like some others have), they're still protected by the traditional part like they would have been, with no leaking of all the data.

Luckily the majority of websites and Internet traffic go to the three cloud companies
