ASP.NET中使用MD5和SHA1算法加密 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　你的主页或者你管理的网站有各种密码需要保护把密码直接放在数据库或者文件中存在不少安全隐患所以密码加密后存储是最常见的做法在ASP NET中实现加密非常容易

　　 NET SDK中提供了CookieAuthentication类其中的HashPasswordForStoringInConfigFile方法可直接使用MD 和SHA 算法例子如下　　file: encrypting aspx＜%@ Page language= c# Codebehind= encrypting cs AutoEventWireup= false Inherits= encrypting encrypting %＞＜＞＜head＞＜meta name= GENERATOR Content= Microsoft Visual Studio ＞＜meta name= CODE_LANGUAGE Content= C# ＞＜/head＞＜body＞＜form method= post runat= server ＞＜asp:TextBox id=TextBox runat= server ＞＜/asp:TextBox＞＜asp:Button id=Button runat= server Text= encrypting ＞＜/asp:Button＞Encrypting Password(MD ):＜asp:Label id=MD runat= server ＞＜/asp:Label＞＜/form＞＜/body＞＜/＞file:encrypting csnamespace encryptingusing 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 MD ;　protected System Web UI WebControls Button Button ;　protected System Web UI WebControls TextBox TextBox ;　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()　　　Button Click += new System EventHandler (this Button _Click);　　this Load += new System EventHandler (this Page_Load);　　public void Button _Click (object sender System EventArgs e)　　　MD Text = CookieAuthentication HashPasswordForStoringInConfigFile(TextBox Text MD );　　//SHA use CookieAuthentication HashPasswordForStoringInConfigFile(TextBox Text SHA );
