ASP.NET中用MD5和SHA1算法加密

2010-08-28 10:46:13來源:西部e網作者:

  你的主頁或者你管理的網站有各種密碼需要保護,把密碼直接放在數據庫或者文件中存在不少安全隱患,所以密碼加密后存儲是最常見的做法。在ASP.NET中實現加密非常容易。.NET SDK中提供了CookieAuthentication類,其中的HashPasswordForStoringInConfigFile方法可直接使用MD5和SHA1算法。例子如下:

  file: encrypting.aspx

<%@ Page language="c#" Codebehind="encrypting.cs" AutoEventWireup="false" Inherits="encrypting.encrypting" %>
<html><head>
<meta name="GENERATOR" Content="Microsoft Visual Studio 7.0">
<meta name="CODE_LANGUAGE" Content="C#"></head>
<body>

<form method="post" runat="server">


<asp:TextBox id=TextBox1 runat="server"></asp:TextBox>
<asp:Button id=Button1 runat="server" Text="encrypting"></asp:Button>
Encrypting Password(MD5):
<asp:Label id=MD5 runat="server"></asp:Label>
</form>

</body></html>

file:encrypting.cs

namespace encrypting
{
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.Web.Security;
/// <summary>
/// Summary description for encrypting.
/// </summary>
public class encrypting : System.Web.UI.Page
{
 protected System.Web.UI.WebControls.Label MD5;
 protected System.Web.UI.WebControls.Button Button1;
 protected System.Web.UI.WebControls.TextBox TextBox1;

 public encrypting()
 {
  Page.Init += new System.EventHandler(Page_Init);
 }
 protected void Page_Load(object sender, EventArgs e)
 {
  if (!IsPostBack)
  {
   //
   // Evals true first time browser hits the page
   //
  }
 }
 protected void Page_Init(object sender, EventArgs e)
 {
  //
  // CODEGEN: This call is required by the ASP+ Windows Form Designer.
  //
  InitializeComponent();
 }
 /// <summary>
 /// Required method for Designer support - do not modify
 /// the contents of this method with the code editor.
 /// </summary>
 private void InitializeComponent()
 {
  Button1.Click += new System.EventHandler (this.Button1_Click);
  this.Load += new System.EventHandler (this.Page_Load);
 }
 public void Button1_Click (object sender, System.EventArgs e)
 {
  MD5.Text = CookieAuthentication.HashPasswordForStoringInConfigFile(TextBox1.Text,"MD5");
  //SHA1 use CookieAuthentication.HashPasswordForStoringInConfigFile(TextBox1.Text,"SHA1");
 }
}
}

  注意:類CookieAuthentication的namespace是System.Web.Security。
