AES 加密 PHP 和 JAVA 互通

PHP代码:

 <?php
 class Security {
     public static function encrypt($input, $key) {
     $size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB);
     $input = Security::pkcs5_pad($input, $size);
     $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_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;
     }

     private static function pkcs5_pad ($text, $blocksize) {
         $pad = $blocksize - (strlen($text) % $blocksize);
         return $text . str_repeat(chr($pad), $pad);
     }

     public static function decrypt($sStr, $sKey) {
         $decrypted= mcrypt_decrypt(
         MCRYPT_RIJNDAEL_128,
         $sKey,
         base64_decode($sStr),
         MCRYPT_MODE_ECB
     );

         $dec_s = strlen($decrypted);
         $padding = ord($decrypted[$dec_s-1]);
         $decrypted = substr($decrypted, 0, -$padding);
         return $decrypted;
     }
 }

 $key = "1234567891234567";
 $data = "example";

 $value = Security::encrypt($data , $key );
 echo $value.'<br/>';
 echo Security::decrypt($value, $key );
