格转换的一些代码

D5CryptoServiceProvider MD5CSP = new MD5CryptoServiceProvider();
   byte[] MD5Source = System.Text.Encoding.UTF8.GetBytes(Sourcein);
   byte[] MD5Out = MD5CSP.ComputeHash(MD5Source);
   return Convert.ToBase64String(MD5Out);

System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(temp_str, "MD5");//MD5加密
