I am still not convinced that akcipher is good match for key exchange methods. I think we should try to introduce a new abstraction here. Overloading set_pub_key() with DH params and using decrypt() for private/public key pair generation seems not a good fit. It does not really match. And as I said before, we know for certain that ECDH has to happen as well. So we need to forward look into making that fit as well.
