<a name="Example_Usage">Example Usage</a>

1. Alice generates a new keypair and sends her public key to Bob.

#{ secret := AliceSecretKey, public := AlicePublicKey } = luke:keypair().

2. Bob uses Alice's public key to compute the shared secret and a public key that he then sends back to Alice.

#{ shared := BobSharedSecret, public := BobPublicKey } = luke:sharedb(AlicePublicKey).

3. Alice computes the shared secret using her own secret key and Bob's public key.

AliceSharedSecret = luke:shareda(AliceSecretKey, BobPublicKey).

4. You can now verify that the shared secret is the same.

AliceSharedSecret =:= BobSharedSecret.
