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]);
