@Test
public void javaDecryptWithSecretKey() throws Exception {

    String contents = TestConstants.TEST_ENCRYPTED_RESOURCE;
    byte[] keyBytes = TestConstants.TEST_ENCRYPTION_KEY.getBytes();
    String[] parts = contents.split(":");

    byte[] initVector = Base64.decodeBase64(parts[0].getBytes());
    byte[] decodedValueBytes = Base64.decodeBase64(parts[1].getBytes());

    SecretKey originalKey = new SecretKeySpec(decodedKeyBytes, 0, decodedKeyBytes.length, "AES");
    Cipher cipher = Cipher.getInstance(originalKey.getAlgorithm() + "/CBC/PKCS5Padding");
    cipher.init(Cipher.DECRYPT_MODE, originalKey, new IvParameterSpec(initVector));
    byte[] decryptedBytes = cipher.doFinal(decodedValueBytes);

    assertEquals(TestConstants.TEST_DECRYPT, new String(decryptedBytes));
