PHP des加密输入怎么才能和JAVA的des输出一至呢
Java加密代码

Java code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->    /**     * 传输的关键数据加密     * @param keyData 需加密值     * @param timestamp  时间戳     * @param dataSecret  密钥     * @return String 加密数据     */    public static String encryptKeyData(String keyData, Long timestamp, String dataSecret) {        DateFormat df = new SimpleDateFormat(Constants.DATE_TIME_FORMAT);        df.setTimeZone(TimeZone.getTimeZone(Constants.DATE_TIMEZONE));        keyData = df.format(new Date(timestamp)) + "aop" + keyData;        return desEncryptToBase64(keyData, dataSecret.getBytes());    }


PHP加密代码

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->    function encrypt($input)     {                $size = mcrypt_get_block_size('des', 'ecb');                  $input = $this->pkcs5_pad($input, $size);                  $key = $this->key;                 $td = mcrypt_module_open('des', '', 'ecb', '');               $iv = @mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);              @mcrypt_generic_init($td, $key, $iv);                 $data = mcrypt_generic($td, $input);                  mcrypt_generic_deinit($td);              mcrypt_module_close($td);                 $data = base64_encode($data);                 return $data;         }     function pkcs5_pad ($text, $blocksize) {                  $pad = $blocksize - (strlen($text) % $blocksize);                 return $text . str_repeat(chr($pad), $pad);       }  


每次加密出来的内容都是不一样的,头疼,必须是PHP配合JAVA的算法

网上不是蛮多这方面的你看看是否有帮助?

function encrypt($str, $key)

{

$block = mcrypt_get_block_size('des', 'ecb');

$pad = $block - (strlen($str) % $block);

$str .= str_repeat(chr($pad), $pad);

  

return mcrypt_encrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_ECB);

}

  

function decrypt($str, $key)

{

$str = mcrypt_decrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_ECB);

  

$block = mcrypt_get_block_size('des', 'ecb');

$pad = ord($str[($len = strlen($str)) - 1]);

return substr($str, 0, strlen($str) - $pad);

}

  

?>

以前也遇到过类似的加解密问题,不知道是两种语言对数据的处理方式不一样还是其它什么原因,后来实在没辙了,用javabridge解决的
------解决方案--------------------
没有看到 php 中对应
 keyData = df.format(new Date(timestamp)) + "aop" + keyData;
的部分

感觉两者的算法不一致

------解决方案--------------------
最好把java代码贴全咯。copy过来就能运行那种,咱是phper
