   //           優點為可以由多個處理器來平行處理ㄧ個很大的資料。缺點為如果資料
   //           的內容有重複出現的部分,而且重複資料的長度剛好與加密區塊等長,
   //           則這些重複出現的部分經過加密後會出現相同的結果。
   //  PKCS5Padding: 如果要加密的資料不是8個(如DES加密演算法)或
   //           16個(如AES加密演算法)位元組的整數倍,則必須在欲加密資料的
   //           尾端加入若干個位元組來湊成整數倍。PKCS5Padding是一種
   //           補足不足位元組的方法。
