小程序如何进行AES加密？要求：AES加密Key、IV(加密偏移量)都是tyte[]数组。下面是一段安卓代码，我需要将此代码翻译成js引用到我的小程序里面去使用。我试过网上的一些小程序AES加密的方法，key和iv都是字符串，不是tyte[]数组，怎么处理？private static final byte[] IV = new byte[]{65, 20, -91, 123, -102, 126, 105, -28, -15, 13, 51, 32, 53, 45, -97, -40};

private static final byte[] KEY = new byte[]{-49, 59, -97, -82, 5, -125, -92, -15, -7, -4, 95, -87, 85, -47, -34, -10};

private void test(String originStr){
    try {
        byte[] encrypt = encrypt(IV, KEY, originStr.getBytes("utf-8"));
        String base64 = Base64.encodeToString(encrypt, Base64.NO_WRAP);
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < base64.length(); i++) {
            char c = base64.charAt(i);
            switch (c) {
                case '=':
                    sb.append('二');
                    break;
                case '+':
                    sb.append('十');
                    break;
                case '/':
                    sb.append('丿');
                    break;
                default:
                    sb.append(c);
                    break;
            }
        }
        String dstStr = sb.toString();
        Log.d(TAG, String.format("originStr: %s, dstStr: %s", originStr, dstStr));
    } catch (Exception e) {
        Log.e(TAG, e.getMessage(), e);
    }
}

public static byte[] encrypt(byte[] iv, byte[] key, byte[] input) throws NoSuchPaddingException, NoSuchAlgorithmException, BadPaddingException, IllegalBlockSizeException, InvalidAlgorithmParameterException, InvalidKeyException {
    SecretKeySpec secretKeySpec = new SecretKeySpec(key, "AES");
    Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
    IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);
    cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, ivParameterSpec);
    return cipher.doFinal(input);
}
