我正在对我的文件实施加密/解密。代码如下。我找不到问题。我有什么想念的吗？我需要实现128位AES加密。有什么问题吗？结果以错误结束

 "javax.crypto.BadPaddingException: error:1e06b065:Cipher functions:EVP_DecryptFinal_ex:BAD_DECRYPT"

请帮我。

private static byte[] encodeFile(byte[] yourKey, byte[] fileData)
        throws Exception {
    byte[] encrypted = null;
    SecretKeySpec skeySpec = new SecretKeySpec(yourKey, 0, yourKey.length, "AES");
    Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7PADDING");
    cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
    encrypted = cipher.doFinal(fileData);
    return encrypted;
}

private static byte[] generateKey() throws NoSuchAlgorithmException {
    byte[] keyStart = "This is my key".getBytes();
    String id = "dummypass";
    int iterationCount = 1000;
    int saltLength = 32;
    int keyLength = 128;
    SecureRandom random = new SecureRandom();
    byte[] salt = Arrays.copyOf(keyStart,saltLength);
    random.nextBytes(salt);
    KeySpec …
