博客提及在webconfig的system.web节点下添加内容，涉及machineKey生成的算法，与信息技术中后端开发的配置相关。

在webconfig中system.web节点下添加：

<system.web>

    <machineKey validationKey="3FF1E929BC0534950B0920A7B59FA698BD02DFE8" decryptionKey="280450BB36319B474C996B506A95AEDF9B51211B1D2B7A77" decryption="3DES" validation="SHA1"/>

</system.web>

machineKey生成的算法:


<script language="c#" runat="server">

	#region Page_Load

	private void Page_Load(object sender, System.EventArgs e)
	{
		if (!Page.IsPostBack)
		{

			var validationKey = CreateKey(20);

			var decryptionKey = CreateKey(24);

			Response.Write("validationKey:"+validationKey);
			Response.Write("<br>");
			Response.Write("decryptionKey:"+decryptionKey);
		}
	}

	#endregion


	 protected string CreateKey(int len)
	 {

			byte[] bytes = new byte[len];

			new System.Security.Cryptography.RNGCryptoServiceProvider().GetBytes(bytes);

			  StringBuilder sb = new StringBuilder();

			  for(int i = 0; i < bytes.Length; i++)

			  {   

				   sb.Append(string.Format("{0:X2}",bytes[i]));

			  }

			  return sb.ToString();

	 }
	

</script>
