你
主页或者你管理网站WebSite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做法
在ASP.NET中实现加密非常容易.NET SDK中提供了CookieAuthentication类其中HashPasswordForStoringInConfigFile思路方法可直接使用MD5和SHA1算法例子如下:<br>file: encrypting.aspx<br>
<%@ Page language="c#" Codebehind="encrypting.cs" AutoEventWireup="false" Inherits="encrypting.encrypting" %><br>
<html><head><br>
