The same way you establish the encryption key. Instead of setting up
a shared 256-bit key fer encryption, you set up a shared 512-bit key
and use half of it for encryption and the other for authentication.
There are other ways to do it, too, but this is the simplest, safest
and most obvious one.

Come on, it's not like *this* is anything people hadn't completely
figured out decades ago.
