### Question:
PBE { public static byte[] initSalt() { byte[] salt = new byte[8]; Random random = new Random(); random.nextBytes(salt); return salt; }  static byte[] encrypt(byte[] data, byte[] key, byte[] salt); static byte[] decrypt(byte[] data, byte[] key, byte[] salt); static Key generateRandomKey(byte[] key); static AlgorithmParameterSpec getAlgorithmParameterSpec(byte[] salt); static byte[] initSalt();  }### Answer:
@Test public void testInitSalt() { assertNotNull(PBE.initSalt()); }
