MD5加密

strPwd = txtPwd.Text;
strPwd = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strPwd,"MD5");

這樣就可以將你的密碼進行MD5加密了

  public string GetMD5(string sDataIn)
  {
   string Result;
   MD5CryptoServiceProvider md5=new MD5CryptoServiceProvider();
   byte[]bytValue,bytHash;;
   bytValue = System.Text.Encoding.UTF8.GetBytes(sDataIn);
   bytHash = md5.ComputeHash(bytValue);
   md5.Clear();
   string sTemp="";
   for(int i=0;i<bytHash.Length;i++)
   {
    sTemp+=bytHash[i].ToString("X")..PadLeft(2,'0');
   }
   Result = sTemp.ToLower();
   return Result.Substring(8,16);
  }
