23/**
24 * When a user first initializes TextSecure, a few secrets
25 * are generated. These are:
26 *
27 * 1) A 128bit symmetric encryption key.
28 * 2) A 160bit symmetric MAC key.
29 * 3) An ECC keypair.
30 *
31 * The first two, along with the ECC keypair's private key, are
32 * then encrypted on disk using PBE.
33 *
34 * This class represents the ECC keypair.
