C#中用MD5实现数据加密

using System.Security.Cryptography;
using System.Text;
  private void button1_Click(object sender, System.EventArgs e)
  {
   byte[] bt=UTF8Encoding.UTF8.GetBytes(textBox1.Text );//UTF8需要对Text的引用
   MD5CryptoServiceProvider objMD5;
   objMD5=new MD5CryptoServiceProvider ();
   byte[] output=objMD5.ComputeHash (bt);
   textBox2.Text =BitConverter.ToString (output); 
  }
