### Question:
AesKeyHelper { public static String createRandomBase64Key() throws SakuliCipherException { try { return new BASE64Encoder().encode(createRandomKey().getEncoded()); } catch (Exception e) { throw new SakuliCipherException(e, "Unexpected error during converting of AES key to Base64"); } }  static SecretKey createRandomKey(); static String createRandomBase64Key(); static void printRandomBase64Key(); static SecretKey readBase64Keay(String base64Key); static final int KEYSIZE; static final String ALGORITHM; }### Answer:
@Test public void testCreateRandomBase64Key() throws Exception { Assert.assertNotEquals(AesKeyHelper.createRandomKey().getEncoded(), AesKeyHelper.createRandomKey().getEncoded()); Assert.assertNotEquals(AesKeyHelper.createRandomBase64Key(), AesKeyHelper.createRandomBase64Key()); }
