Re: [webauthn] Can the private keys be used for other cryptographic operations? (#1595)

@certainlyNotHeisenberg ECDH is essentially a pseudo-random function from the perspective of either participant (assuming a fixed key for the other party, you pass some input and receive a random-looking value determined by the input), so I think this should cover anything you could do with ECDH where you control only one of the keys.
