title: Generating AES key after ECDH
body: <p>I am using ECDH to have a shared secret between Alice and Bob one running on Android and the other on embedded. My understanding is that the best practice is that both sides generate an AES key to encrypt messages. Can someone send some example on how both sides Alice and Bob generate the same AES key after they have agreed on a shared secret by using ECDH?</p>
