Luke

Version: 1.3.0 (New Hope: 20160815)

Authors: Alexander Færøy (ahf@0x90.dk).

Luke is an Erlang NIF for the post-quantum key exchange: A New Hope.

For more information about A New Hope, including the paper itself, see github.com/tpoeppelmann/newhope and cryptojedi.org.

Luke also ships with optional support for the Tor implementation of A New Hope. Use the luke_tor module instead of luke if you have a need for that.

Example Usage

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.
