EllswiftExchange

Example:

    privkeyBytes := []byte{...}
    pubkeyOurs := []byte{...}
    pubkeyTheirs := []byte{...}

    ex, err := NewEllswiftExchangeFromKeys(secp256k1.PrivKeyFromBytes(privkeyBytes), pubkeyOurs)
    if err != nil {
        return err
    }

    sharedSecret, err := ex.ComputeSharedSecret(pubkeyTheirs, tst.isInit)
    if err != nil {
        return err
    }

    // sharedSecret is the shared secret used for encrypting the session
