这个方法可以将用户提供的字符变成乱码，然后存储起来，甚至可以 存储在cookies中。
hashpasswordforstoringinconfigfile方法使用起来很简单，它支持"sha1"和"md5"加密算法。
下面的代码简单的演示了关于其用法：
<%@ page language="c#" %>
<%@ import namespace="system.web.security" %>
<html>
<head>
<script language="c#" runat="server">
public void encryptstring(object sender, eventargs e)
{
sha1.text = formsauthentication.hashpasswordforstoringinconfigfile(txtpassword.text,"sha1");
md5.text =formsauthentication.hashpasswordforstoringinconfigfile(txtpassword.text, "md5") ;
}
</script>
</head>
<body>
<form runat="server" id="form1">
<p>
<b>original clear text password: </b>
<br/>
<asp:textbox id="txtpassword" runat="server" />
<asp:button runat="server" text="encrypt string" onclick="encryptstring" id="button1" />
</p>
<p>
<b>encrypted password in sha1: </b>
<asp:label id="sha1" runat="server" />
</p>
<p>
<b>encrypted password in md5: </b>
<asp:label id="md5" runat="server" />
</p>
</form>
</body>
</html>
正如你所看到的这样简单易用。我们可以把这段加密程序封装在一个函数里便于重复的使用。代码如下：
public string encryptpassword(string passwordstring,string passwordformat )
{
if (passwordformat="sha1")
{
encryptpassword=formsauthortication.hashpasswordforstoringinconfigfile(passwordstring ,"sha1");
}
elseif (passwordformat="md5")
{
encryptpassword=formsauthortication.hashpasswordforstoringinconfigfile(passwordstring ,"md5");
}
else
{
encryptpassword="";
}
}
md5的一些应用
string paykey = getpaykey(webdataparse.tryintparse(partner, 0));
string signmsgval = partner + out_orderid + userid + serverid + total_fee + notify_url + paykey;
signmsgval = system.web.security.formsauthentication.hashpasswordforstoringinconfigfile(signmsgval, "md5").toupper();
if (signmsgval == signmsg)
return true;
