Java（Android）aes-128-cbc解密爲明文不一致性

Question

我在Java（Android）中使用aes-128-cbc將明文加密爲密文。我能夠在PHP中將這個密文解密爲相應的明文，但不能在Java本身中解密。

用於加密的Java代碼是如下，

String iv = "0000000000000000"; //Ignore security concerns 
IvParameterSpec ivspec; 
ivspec = new IvParameterSpec(iv.getBytes()); 

String plaintext = "Top Secret Data"; 
byte[] encrypted = null; 

Cipher cipher; 
cipher = Cipher.getInstance("AES/CBC/NoPadding"); 
cipher.init(Cipher.ENCRYPT_MODE, seckey, ivspec); 
encrypted = cipher.doFinal(padString(plaintext).getBytes()); 

ciphertext = Base64.encodeToString(encrypted, Base64.DEFAULT); 

Log.i("Encrypted Base64 Data", ciphertext); 

相應PHP代碼，其能夠解密此成功地是如下，

public function decrypt($data) 
{ 
    $key = $_SESSION['sessionkey']; 
    $iv = "0000000000000000"; 
    $data = base64_decode($data); 

    $encobj = mcrypt_module_open('rijndael-128', '', 'cbc', $iv); 
    mcrypt_generic_init($encobj, $key, $iv); 
    $decrypted = mdecrypt_generic($encobj, $data); 

    mcrypt_generic_deinit($encobj); 
    mcrypt_module_close($encobj); 

    return utf8_encode(trim($decrypted)); 
} 

用於解密的有問題的Java代碼，其反轉到錯誤的明文如下

String iv = "0000000000000000"; 
IvParameterSpec ivspec; 
ivspec = new IvParameterSpec(iv.getBytes()); 

byte[] decrypted = null; 

Cipher cipher; 
cipher = Cipher.getInstance("AES/CBC/NoPadding"); 
cipher.init(Cipher.DECRYPT_MODE, seckey, ivspec); 
decrypted = cipher.doFinal(Base64.decode(ciphertext, Base64.DEFAULT)); 
Log.i("Decrypted Data",decrypted.toString()); 

我會讚賞如果有人能指出Java解密代碼出了什麼問題，就吃了它。

嘗試此

Cipher cipher; 
    cipher = Cipher.getInstance("AES/CBC/NoPadding"); 
    cipher.init(Cipher.DECRYPT_MODE, seckey, ivspec); 
    decrypted = cipher.doFinal(Base64.decode(ciphertext, Base64.DEFAULT)); //byte[] 
    String result = new String(decrypted); 
    Log.i("Decrypted Data",result);
