PHP des加密输入怎么才能和JAVA的des输出一至呢

Java加密代码

	/**
	 * 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

	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？

<?php



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);

}



?>

这些我都试过了，出来的结果还是不一样

[coder]

用相同的第三方加密程序不就行了

[代码如诗]

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

[xuzuning]

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

最好把java代码贴全咯。copy过来就能运行那种，咱是phper
