//首先將字串轉換為位元組數組,這與編碼有關
     string str=textBox1.Text;
   
      byte[]   bytes = Encoding.ASCII.GetBytes(str);
   
    //選擇簽名方式,如:RSA和DSA
  
   DSACryptoServiceProvider dsac = new DSACryptoServiceProvider();
      byte[]  sign = dsac.SignData( bytes );

   ASCIIEncoding encoding = new ASCIIEncoding( );
   textBox2.Text  = encoding.GetString( bytes );
   ASCIIEncoding encoding2 = new ASCIIEncoding( );
   textBox3.Text  = encoding.GetString( sign );
   
   //sign 便是出來的簽名結果
  
   //進行認證
    DSACryptoServiceProvider dsac2 = new DSACryptoServiceProvider();

    dsac2.FromXmlString(dsac.ToXmlString(false));

  
    bool ver = dsac2.VerifyData( bytes  ,sign);

     if(ver)
