重写PHP Rijndael算法到Java（安卓）重写、算法、Rijndael、PHP

我需要连接在Java中codeA字符串和PHP的地方，结果一定是一样的。

I need to encode a string in Java and php where the result must be the same.

在以下条件下给出：

算法：RIJNDAEL算法-128 键：5P443m2Q1R9A7f5r3e1z08642 模式：ECB 初始化向量：N / A（由于我们使用的是欧洲央行，IV的被忽略）

字符串连接code：201412181656005P443m2Q1R9A7f5r3e1z08642

 <?php
        class Cipher
        {
            private $securekey, $iv;

            function __construct($textkey)
            {
                $this->securekey = $textkey;
                $this->iv = mcrypt_create_iv(32);
            }

            function encryptR($input)
            {
                $enc = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $this->securekey, $input, MCRYPT_MODE_ECB, $this->iv);
                return base64_encode($enc);
            }

            function decryptR($input)
            {
                return trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $this->securekey, base64_decode($input), MCRYPT_MODE_ECB, $this->iv));
            }
        }

        $raw_text = '201412181656005P443m2Q1R9A7f5r3e1z08642';
        $secretKey = '5P443m2Q1R9A7f5r3e1z08642';

        $cipher = new Cipher($secretKey);
        $encrypted = $cipher->encryptR($raw_text);     
?>
