  1. function WADecrypt($src, $key){
      $pkey = $key;
      while (strlen($pkey)<16)
        $pkey .= '0';
      $data = explode('|',$src);
      $iv = $data[0];
      $enc = base64_decode($data[1]);
      $dec = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $pkey, $enc, MCRYPT_MODE_CBC, $iv);
      $block = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, 'cbc');
      $pad = ord($dec[($len = strlen($dec)) - 1]);
      return substr($dec, 0, strlen($dec) - $pad);
    }
